would be required to react completely with 3 g of hydrogen gas?​

Answer 1

Answer:

24 g

Explanation:

Hydrogen and oxygen combine in the ratio of 1 : 8 by mass to form water. What mass of oxygen gas would be required to react completely with 3 g of hydrogen gas? Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.

Answer 2

Hello Mate!

Question :-

• Hydrogen and oxygen combine in the ratio of 1 : 8 by mass to form water. What mass of oxygen gas would be required to react completely with 3 g of hydrogen gas?

Solution :-

Law of constant proportions' states that composition of a compound is always fixed.

Applying this

∵ 1 g of hydrogen gas combines with oxygen = 8 g

∴ 3 g of hydrogen gas will combine with oxygen = 8 x 3 = 24 g Ans.
