About the following systems below:I gold II mineral water III water + oil IV atmospheric airIt is correct to say that:O a III and IV are heterogeneous. 0 b. II and ...

Classify each of these with regard to the type of matter (element, compound, heterogeneous mixture, or homogeneous mixture). Explain your choice in each case. (a) A cup of coffee (b) $\mathrm{A}$ soft drink such as a Coke or Pepsi (c) A piece of Dry Ice (a solid form of carbon dioxide)

So say a pure drinking water if you're bringing water, could be if a classified ad components which is, uh, in May, Opt ways consists of ah, hydrogen and oxygen be the south the water, which is solution. So it's definitely ah, a solution. Which sounds could, you know, I could have complete solving water So it's all for my uniform composition. You're on the phone composition. So it's a homogeneous home. Uh, genius. Yeah, Mixture. And the Haley. Um So hey, Liam is adamant Is on in contains one adamant Hey, beom and, uh, say wasa Well, this is ah, uh, tricky. So if you don't considers ah, plan tens and other dissolved of particles to seawater could betray as a similar as a Saudi Saudi water. But it's okay content to stay south. So is, ah, solution. So it's a homogeneous Ah, yee's air. So it's, uh, home years because, uh, uh has uniformed composition of our the gases like oxygen, nitrogen, all these uniforms composed in there. So it's Ah, home genius. Make sure Oh, sorry. It seems that home genius there. No iam Sorry

In this problem, we are given five substances on. We have to classify these as elements. Are compound orders homogeneous? Make sure I always had to. Genius picture. Before we answer this problem, let us first understand about element Compound Homogeneous. Make sure, and a heterogeneous mixture element is a substance made up off only one type of Addams, while a compound is a substance made up off more than one type of atoms. Homogeneous mixture is a mixture with uniformed composition. Trot while heterogeneous mixture is a mixture that is very in composition in different parts. Now let's take each off the substance is given and classify. These first one is a pure drinking water. This is a compound. It is a compartment off hydrogen and oxygen so but be gives salty water. Salty water is, ah, homogeneous mixture. Support see is helium. Helium is an element. It is made of off helium atoms in somebody were given seawater. Seawater is a heterogeneous mixture. It is heterogeneous mixture because apart from sand and water, which might have a uniformed composition tour, they send another impurities in seawater, which make it a heterogeneous mixture. If somebody were given here, Here is a homogeneous mixture with the reform composition throat

Before identifying each of these as an element compound. Homogeneous mixture. Heterogeneous mixture, Let's define these terms. An element is matter that is composed of only one type of atom where atoms are defined based upon the number of protons they have elements are found in the periodic table. A compound contains more than one type of atom. That is chemical that are chemically bonded to each other. So they contain multiple elements found on the periodic table. Chemically bonded. Homogeneous mixture is a type of matter that contains a mixture of elements and compounds uniformly at the ionic, atomic and molecular level where there are no regions of differing properties. Heterogeneous mixture is the same thing, a mixture of elements and or compounds, but they're not mixed uniformly at the molecular level. Therefore there are regions of varying properties. So a silver in get in get refers to a pure amount of silver. So silver ink, it would be an element. Silver is found on the periodic table, silver or any time we're talking about, or it's being mined from the ground. The ground is dirty. The ground contains a mixture of whole bunch of things and we can look at it and we can see regions of differing properties, different colors and so forth. So this is a heterogeneous mixture. Silver oxide is a compound that contains the element silver and oxygen, and then silver alloy would be a mixture of silver with some other type of metal uniformly mixed at the atomic level. So this is a homogeneous mixture.

First, let's talk about the difference between a pure substance, um, homogenous mixture and a hetero mixture header. Jesus mixture. So pure sessions is only one thing. Whatever the thing is, water would, um Woods. Not a good example. Put one compound table, salt, some one compound her element. Just one thing, um, hum, homogeneous is looks the same, but we have multiple things and that this would be like Kool Aid. I have coffee sitting on my table right now. The coffee looks the same throughout, um, So, uh, after it's been open door before it's been opened. I'm not after you shaked it in. Everything costs everywhere with your Mentos. That actually would be a good head row, so good hetero would be so it looks different. So what? Getting mentors and soda or my favorite heterogeneous make sure is a chocolate chip cookie. You can see the chocolate chips in it. So we're gonna use these kind of quick definitions here to classify some substances. So a is air. Air is a mixture of lots of things. It's not just oxygen, but it looks the same throughout. So that is homogeneous. You, um, aerosol. So this would be something that is kind of sprayed out of a can like an aerosol can. So inside, um, it's probably hetero, but once you squeeze it it out, it's a modernist thio. Keep those particles, um, out of consistent spray pattern. They have to put some things under pressure, and, um so it it is a homogenous mixture. Soil is hetero. That is a mixture, and you can see the different parts of soil, whether it be, um, the potting soil that you buy that has those white little things in it. Or if you could just go outside, you'll see in the soil that there's rocks. There's worms, there's bits of detritus, bits of decaying things. So that's hetero. Um, de is water. Water only has h 20 compounds in it, so that is pure. He is sediment. Um, which sediment is hetero again? It's similar to soil. You can see all the pieces, Um, in the F is muddy water again hetero. Um, because you have water, you have mud. You have the thing. Other things that could possibly be in the muddy water like leaves so you can see all of the pieces that's hetero
