Answer:
.122 mols of KCl
Explanation:
<u>Read the explanation </u><u><em>while</em></u><u> looking at the picture.</u>
We star with 15g because it's wat they give us:
<u>15g of KCIO3 will cancel out with 123g of KCIO3</u> (molar mass)
~Grams of KCIO3 are canceled out.~
<u>That 123g of KCIO3 is the same as 1 mol of KCIO3</u>
Then we use mole to mole ratio:
<u>1 mol of KCIO3 equals 2 mols of KCIO3</u> -- 2 moles from the equation
The <u>2 mols of KCIO3 is equal to 2 mols of KCl</u> (from equation)
Multiply the numbers on top. Multiply the numbers on the bottom. Then divide. You get:
This sounds confusing. But the picture below is the format.
The SAME COLOR are the ones that cancel out.
Answer:
The solubility curve helps us to predict which substance will crystallize out first from a solution containing two or more solutes. The solubility curve helps us to compare the solubilities of different substances at the same temperature.
Aluminium is overall more reactive because it can loose electrons easier and therefore in a displacement reaction can force electrons upon less reactive metals such as chromium
I'll get back to you on it.
Answer:
the heat required to raise the temperature of the unit mass of a given substance by a given amount
