Question

144 grams of pure water composed by passing electricity 16 mass of hydrogen and 126 gram of oxygen are obtained which chemical law is illustrated by the statement

Answer 1

Answer:

Law of Constant Proportions

m = 144g(Water)

Mass of H = 16g

Mass of O = 128g

16g +128g = 144g

By the Law - Ratio of Hydrogen To Oxygen = 16:128 = 16/128 = 1/8 = 1:8(Signifies the Law)

Answer 2

Explanation:

Law of Conservation of mass is confirmed here. Law of constant proprtion. so when 16 gm of hydrogen reacted with the 128 gm of oxygen It will lead to the formation of 144 gm of H2O

but

ln your question 126 gram of oxygen is wrong so please check
