Write a chemical equation for the neutralization of acetic acid with aqueous sodium hydroxide to give aqueous sodium acetate plus water.

Here who have to write the equation for the reaction of hydrochloric acid with magnesium hydroxide. And then we have to balance the equation. Hcl hydrochloric acid, yeah, sweet magnesium hydroxide, right? And this acid and base rehabs and produces salt which is magnesium chloride and water. Now we have to balance this equation. The product side to see L. A. Town. So less place to hair. Now reactant side has two hydrogen atoms here and two hydrogen atoms here, altogether four hydrogen atoms. So let's put to hair. Now oxygen atoms here, two oxygen atoms and the reactant side has two oxygen atoms, one mg Vietnam, one mg aton. So the reaction is balanced. So the balance reaction between hydrochloric acid and magnesium hydroxide is to a sale plus M g o h. Or twice produces mg cl two plus two H two.

So in this video, we're gonna talk about Question 36 from chapter 20 which asks us to write a balanced equation describing the reaction of aluminum metal with concentrated alias sodium hydroxide. So when aluminum reacts with hydroxide ions, it actually forms rather than an ionic compound. A complex I arm, um, where we have a ll a wage for, um, And since we know that aluminum always takes the plus three oxidation state are a wage four gives us a minus one charge overall. And then this, um, this negatively charged an eye on will form an ionic compound with our sodium ion. So that will be one of our products. Um, so let's right out the full reaction on balance, it, um So we have a lunar plus sodium hydroxide. And then, since our sodium hydroxide is a curious, um, we know that we also have Htoo, and then the product we're gonna form is our sodium aluminum. You Oh, h four. All right, so there we go. Um, so we need to balance this. Um, So for starters, we have an even number of hydrogen atoms and our products, but on our reactions, we have two hydrogen atoms from water and just one hydrogen atom from our sodium hydroxide. So we haven't even number of, um, we haven't even number hydrogen atoms and our products, but an odd number of hydrogen atoms and our reactant. So if we're gonna have any hope of balancing this, what we need is a coefficient of two in front of our compound that's making our number of hydrogen atoms on our products on Odd. So we're gonna put a two in front of our sodium hydroxide, Um, and then because we have to sodium atoms on the in our reactions, we also need to sodium atoms in our products. So are complex. Eye on on the right hand side also gets a coefficient of two, which gives us two little bottoms and our products eso We also need to aluminum atoms in our reactant. So we get a coefficient of two. Here is Well, um, so now, at this point, we have to sodium atoms to aluminum atoms on, and then we have, um, we have three oxygen atoms on the left, but four oxidant adams on the right eso again. We have an odd number of a certain Adam on the left hand side and an even number on the right. So we're gonna need a coefficient of two. So the molecule that's making our number of oxygen atoms and our reactant odd is the water molecule. So we're gonna take two of those since, um, that will make us have an even number of oxygen atoms. So now we have four oxygen atoms on the left hand side and four oxygen atoms on the right hand side. What about our hydrogen atoms? That's the only thing we haven't totally balanced yet. So so far, we have two hydrogen atoms from our sodium hydroxide plus four hydrogen atoms from our water that gives us six hydrogen atoms are reactant. Um, And then on the right hand side, those or hydroxide ion, give us four hydrogen atoms. So we have to pure hydrogen atoms in our products than inner reactant. So thio balance that we're going to add hydrogen gas H two. So now we're equation was balanced. So the balanced equation is to a l plus two in a oh age plus two h +20 forms to in a l a L O h four plus h two

Cancer problem. 30. Chapter 19 asks to rate a balanced equation Screaming the reaction off aluminum metal with concentrated a curious So you hydroxide. So, um, do this reaction. We have aluminum mental, so that's so unfazed. And they have sodium hydroxide concentrated, and this is a quicks. So looking at be set up for this reaction waken See that this is gonna be a simple single displacement reaction. So we're going to have the n a replace. I mean, aluminum is going to replace the sodium here, so yeah, I was gonna go with that. So what we're gonna have here for action is e l No age, but we know that a l is three plus and no inches one minus. So that means we're gonna have to have three four inches. So we have a m o h. Three, and then we'll are sodium Mr Left over. So what happened to their sodium is just gonna be displaced, and that's to keep the balance of the reaction. So, um, as for the faces of these two things, if they look at the Celje bility charge, you will see that if you look at his eligibility triangle, find out. This is indeed a soul. It's still and then any is on its own. So this is gonna be a solid as well. So, actually, um, So this would be or a single displacement reaction, and now we just want to see if it's balanced. So we have one a moment of over him. We have one aluminum here, so that's fine. And then we have one Any human and we have one any here. So that's one thing. But here we have three, um, hydroxy groups and over here with them one. So we're gonna do is we're gonna have to make this if three. So that's three that now we have three and a over here. We and they have one over here, so we'll also have to make ah three right here. So overall are balanced. Reaction would be AM so plus three and a O. H increase. And that use Hey. Oh, college. Three of those 30 agent. And then we have plus three and A to keep the equation balance now. So this is our final balanced operation. Have this single displacement reaction. Um, but actually, if you look at the activity rules, you'll find out that this reaction does not actually occur. So the answer is actually no reaction. Yeah,

So in Problem 79. Read the question for each reaction described the concentration off sodium hydroxide. So this is the formula of sodium hydroxide any wedge can we found from reacting it with oxalic acid so exotic as it is etched toe to toe for? So we find out the product form from thes reluctance and in the product from the one off the product is sold, so this type of reaction is known as the neutralization reaction. So this reaction is called neutralization reaction, and in the neutralization reaction, the accident based combined to form salt and water. So in the neutralization, we can see that when an acid is added toe an equal amount off base, then each hydrogen iron. Facts with the hydroxide ein toe form a molecular water so the acid and base neutralize each other in a neutralization reaction, and and any compound formed is salt. So this is the reaction off neutralization. So if we consider an example like checks, if it is an acid and basis like MM or edge. So this is in a quest. So the product from From this reaction is sold, which is MX along with H two or so we can consider an example like if HCL is an acid and any which is based and the product form from destruction assault, which is NSCN along with water so coming toe this reaction when any which is reacts with the oxalic acid. So this is the base, and this is the acid. So when these react so the neutralization reaction can take place in this case. So the product from from this reaction is sodium oxalate, which is a NATO see toe, so four and H toe so we can balance this occasion. So this is the two NH, and this is three to each toe. So this type of reaction is also known as the double displacement reaction. So the reaction is also known as double a replacement reaction. So this type of reaction it's also known as double replacement or double displacement reaction and the general equation. The general okay, equation off the double replacement reaction is double replacement reaction is like X plus B y. That can form a Y plus BX because if it is positive and excess negative and B is positive and why is negative so this positive and negative combine each other so that can form a Y plus BX. So basically, the two compounds exchange I owns to produce two new compounds and Qatar in part exchange with the Annan part. So while letting the formula, we read the guardian part first and then the so this type of reaction is also known as the double replacement or double displacement reaction. Okay, so So in this case, when this sodium hydroxide is react with the oxalic acid so we can see that this is the oxalic acid like H toe see toe all four and the sodium hydroxide is like any Ohh. So So basically, this can form the oxalate. I am like we can write details. This can form obsolete and like, see toe offer to minus. And this is known as the obsolete iron. And this is like in a co solution and a positive and H minus. And this is the two h positive. So if we combined with to an image so that conform to any place and this is two of which minus, so we can write in this way, so that means we can see that this negative obsolete. I am combined with the sodium so that can form thesis odium obsolete, which is a need toe See toe all four and along with h toe. So this is the equation so we can write. Finally, the balanced equation like this is Theus, it h two c toe offer, which is known as oxalic acid. So when it reacts with the base, so this is to N a O. H. So the product from from this reaction is salt, which is and need toe see toe offer, which is known as the sodium oxalate and edge, toe and edge toe. So this type of reaction is known as the neutralization reaction or the double replacement reaction, and in this reaction, this ended toe see toe. All four is known as thes sodium oxalate, so this is known as the sodium oxalate, and the C 204 to minus is known as the obsolete ion. So this reaction is known as the neutralization reaction. This reaction is known as neutralization reaction because acid and base combined to form salt and water, and this reaction is also known as the double replacement reaction. So this reaction is also known as the double replacement or double displacement reaction

Often when an earthquake shifts a segment of the ocean floor, a relatively small amplitude wave of very long wavelength is produced. Such waves go unnoticed as they move across the open ocean; only when they approach the shore do they become dangerous (a tsunami or "tidal wave"). Determine the wave speed if the wavelength, $\lambda,$ is $6000 \mathrm{ft}$ and the ocean depth is $15,000 \mathrm{ft}$.
