Question

30g of wood burns with 16g of oxygen. What would be the total mass of gases and the
ash?

Please answer. Best answer will be brainlist and a thanks and excellent rating from me. And also 30 points please answer

Answer 1

Answer:

total mass will be 2400g

Explanation:

C+O2→CO2

3g    8g         11g

Total mass of reactants = mass of carbon + mass of oxygen =3+8=11g

Total mass of reactants = Total mass of products

Hence, the law of conservation of mass is proved.

Further, it also shows carbon dioxide contains carbon and oxygen in a fixed ratio by mass, which is 3:8.

Thus it also proves the law of constant proportions. 3 g of carbon must also combine with 8 g of oxygen only.

This means that (50−8)=42g of oxygen will remain unreacted.

Answer 2

Answer:

total mass will be 46g

Explanation:

30g+16g = 46g

hope it helps
