What is the formula and name of a hydrate that is 85.3$\%$
barium chloride and 14.7$\%$ water?

In problem. 53 water molecules per formula unit. What is the name of hatred and what is its formula? So this question is taken from the topic. Chemical nomenclature. So first, we're 80 formula. So, like, this is the formula. So in this case, this is known as Berry um per chlorate rehydrate. So the name off this compound is very, um para gloried. Try hydrate. Okay, so in this case, basically this very, um existing two plus charge. And this is cl or for minus. So this is known as the park low rate I own. And this three water molecules. So that is why we can use tri hydrate. So, for the water, we use dehydrate. And for three, we use it. Try. So this makes the formula B a c l o for toy story three h 20 which is known as variant per chlorate. Try hatred. And and this is the formula that is B A C l. Or for twice not three h two. And this is the formula. So in this case, there are this. We can see three water molecules are attached with this. Ah, this very, um parte gloried. So which makes the Formula Billion Park. Laura, try hatred. So this is our final formula. So this is the formula, and this is the name.

So in this exercise we have to write the name from the formula or the formula from the name off each of these hydrated Ione compounds. Now you can refer back to how to ride that any compound formula. But in this case, we're just practicing how to name or interpret how thiss is a hydrate. So for the first one we have here, Coble to Foss Faso cobbled is a two plus and still there's a little bit more to the side. So we have called two plus from the shar from the Roman numbers. And then we have fourth faint. And then this is three miners the east, this way, just to cross section the charges. So these two plus will be for the phosphate. And then this tree miners will be for the copper Couples now are in the three here. And then, since this is a poll, atomic won and we have two of them. You should put them in a parenthesis and other too. Now, the rest of the formerly says the hydrate. So Sarah Dodds octa is from eight. So they're eight hydrogen molecules or water, ma Nichols. So this is the first one The second one is beryllium chloride. So we have here the beryllium at home on clothes line. Ah, beryllium is church too. So we don't have to add anything as off from a numbers, uh, or illness this use the writing shunt. Is that a lot? So many moons. And then we have chloride. We also have two water model molecule. So to determine or display the two we used the the eye or the Greek, Um, the six and then hydrate. Two thousand names of the Brazilian pro died. Next we have Grumman three for three now from Ume you have here chromium is three plus because of the from a number. So this is three close Foster A is a small atomic I am for Well, she's three minors now. They're the same charge, so we just need one of each. So this is from the force He had a thought on. These has a three which mean they're three water molecules. H two o. Now we hear we have let him And this is night, right? This is Apple Atomic Eye on channel two. Um, so we have here. Right? So we have a lead fumes? Yeah, And then this is night, right? And all, too. Then we have one more water molecules, so it doesn't need a perfect. It's just hydrate. And that's that. Bethany, lead your nitrate nitrite, hide my treat.

Barium, bromide, barium. We recall having a two plus charge being in Group two A and bromide having a one minus charge. So we need to bro means or bromides for everyone. Barium So we'll take the massive one barium to time. Samassa Breault main to get to 97.14 a m u. The next one It's die nitrogen tri oxide. So to nitrogen ins three Oxygen's take the mass of two times nitrogen plus three times the mass of oxygen to get a formula mass of 76.1 AM you next one is copper one sulfate. So copper has a plus. One charge sulfate we've memorized has a to minus charge. So we need to coppers for every sulfate. So we'll take two times the mass of copper plus the massive sulfur plus four times the mass of oxygen to get a formula mass of to 23.15 a. M u. The last one is hydro, bro. Make acid. The bro Mick came from bromide and bromide has a one minus charge. So we just need one hydrogen with the plus one charge. So we take the massive one hydrogen and one bro mean and we get a formula massive 80.91 a. M. U

Throughout the chemical formulas for each of the following first we have calcium nitrate. Mhm. Mhm. Just the chemical formula C. A. And all three in brackets too. And barium chloride. She was the chemical for me and I PAC. L. two and ammonium phosphates. Yeah. Bring the chemical formula. and in two or 3 the oh four What are the names and charges of all irons present? So for calcium nitrate the two plus just the calcium iron. Mhm. Hello three latest which is the nitrate. Hi Inn. For barium chloride we have varying two plus. Just leave very um iron. Mhm. And cl minus which is the chloride. Fine for ammonium plus feet you have 10 H four plus just the ammonium iron and P. 04 3-. Which is the phosphate. Oh yeah.
