The balanced chemical equation for the reaction of copper (cu) and silver nitrate (agno3) is shown below. cu + 2agno3 es002-1.jpg 2ag + cu(no3)2 how many moles of agno3 must react to form 0.854 mol ag?

Moles of that must be reacted are 0.854 moles.

Explanation:

For the given chemical reaction, the equation follows:

By Stoichiometry of the reaction:

2 moles of silver are produced when 2 moles of silver nitrate is reacted.

So, 0.854 moles of silver is formed when = of silver nitrate is reacted.

Thus, moles of that must be reacted are 0.854 moles.

b) nuclear ive learned that in a pedtrodic table

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is
