Answer 1

Answer:

Explanation:

Ammonia-NH3

Water-H2O

Carbon dioxide-CO2

Answer 2

Answer:

Explanation:

Molecular Formula And Ratio By Mass:-

1 ) Ammonia

NH₃ is the molecula formula

14:3 is the ratio by mass

It means 1 Nitrogen atom combines with 3 Hydrogen atoms to form NH₃ or Ammonia

2 ) Water

H₂O is the molecular formula

1:8 is the ratio by mass

It means 2 Hydrogen atoms combine with 1 Oxygen atom to form H₂O or Water

3 ) Carbon dioxide

CO₂ is the molecular formula

3:8 is the ratio by mass

It means 1 Carbon combines with 2 Oxygen atoms to form CO₂ or Carbon dioxide
