Question

hydrogen and oxygen combine in the ratio of 1:8 by mass to form water. what mass of water would be required to react completely with 4g of hydrogen gas and 34g of oxygen gas?

Answer 1

Answer:

Kindly follow me

Explanation:

Answer: It is given that the ratio of hydrogen and oxygen by mass to form water is 1:8. Then, the mass of oxygen gas required to react completely with 1g of hydrogen gas is 8g. Therefore, the mass of oxygen gas required to react completely with 3g of hydrogen gas is 8 × 3g = 24 g

Answer 2

Answer:

H2 : O2

1 :8

Explanation:

one gram of hydrogen require - 8 g of O2

so ,4g of hydrogen - 4×8

= 32g of O2

so total water formed is 32+4 = 36g
