To solve such this we must know the concept of chemical reaction and dehydration reaction. Therefore, dehydration means to remove water from a compound.
<h3>
What is chemical reaction? </h3>
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Dehydration is a chemical process in which removal of water molecules from a compound take place using suitable reagent. The best reagent for dehydration can be any reagent that is water loving.
Therefore, dehydration means to remove water.

According to avogadro constant, the number of units in one mole of any substance contain 6.022 x10 ^23 atoms
therefore the number of o atoms in one mole of CuSO4 = 6.022 x 10 ^ 23
Answer:
Everyone, this is Ricky. And today we're working on Problem 51 from Chapter 22 and we're gonna determine the number of UNP. Aired electrons for the complex island of CEO seal for minus two I first up, let's determine the charge of art metal ion. So cue is our charge plus four minus one, which is a charge of each chloride ion. The overall charge of minus two Hugh is equal to plus two. I hope this will help
Answer:
28.1
Explanation:
Divide the percentage abundances by 100:
92.2% ÷ 100 = 0.922
4.7% ÷ 100 = 0.047
3.1% ÷ 100 = 0.031
multiply them by their corresponding mass number:
0.922×28 = 25.816
0.047×29 = 1.363
0.031×30 = 0.93
add them all together to get your final answer:
25.816 + 1.363 + 0.93 = 28.109
to one decimal place:
28.1
I hope that helps!!!
Answer:
10.49
Explanation:
3MgO + 2Fe — Fe2O3 + 3Mg
n(Fe2O3) = m/M
=15/159.69
=0.9393199324mol
1 Mol of Fe2O3 = 2 moles of Fe
Therefore n(Fe) =2 * 0.9393199324
=0.1878639865mol
m(Fe) = n*m.m
= 0.1878639865 * 55.8
=10.4828g
