Question

Nitrogen gas reacts with hydrogen gas to produce ammonia gas. How many grams of hydrogen are needed to
react with 100 g of nitrogen to produce 121 g of ammonia?

Answer 1

Answer:

21.35g of hydrogen

Explanation:

from balanced chemical equation 6g of hydrogen react with 28g of nitrogen to produce 34 g of ammonia.so if this is true how many gram of hydrogen react with 100 gram nitrogen to produce 121 g of ammonia

by cris cross multiplication

6g of H2=34g of ammonia

xg of H2=121g of ammonia

so x 121g×6g÷34g

720g of H2÷34

= 21.35g of H2
