C + ZnO ➡️ Zn + CO2

How many moles of zinc will be produced when 0.13 moles ZnO react?

0.12 moles of Zn will produced

Explanation:

Given data:

Number of moles of zinc produced = ?

Number of moles of ZnO react = 0.12 mol

Solution:

Chemical equation:

C + 2ZnO    →   2Zn + CO₂

Now we will compare the moles of Zn with zinc oxide.

                ZnO        :       Zn

                   1           :        2

                 0.12       :     0.12

0.12 moles of Zn will produced.  

i think its 100

i hope this !

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

cu1.4o0.7
