Question

34 grams of H2O decompose to give _______grams of hydrogen and________grams of Oxygen.​

Answer 1

Answer:

6.8 g of h2 and 27.2 g of o2

Explanation:

2h2 + o2 ---> 2h2o

(n) 4 mols 16 mols 20 mols

(g) 4g 16g 20g

if 20g h2o decomposes to give 16g o2

then 1g h2o will decompose to give 16/20 g of o2

then 34g h2o will decompose to give (16/20)×34 = 136/5 = 27.2g of h2

similarly,

if 20g h2o decomposes to give 4g h2

then 1g h2o will decompose to give 4/20 g of o2

then 34g h2o will decompose to give (4/20)×34 = 34/5 = 6.8g of o2
