3. All of us drink water. Water is made up of two elements of nature i.e. Hydrogen and 1M
Oxygen. When two parts of Hydrogen combine with one part of Oxygen, we get
water, chemically also written as HշO. Now answer the following questions based
on the details given above.
(a) What is the ratio between the number of parts of Oxygen to Hydrogen?
(b) What is the ratio between the number of parts of Oxygen to the total parts of
Hydrogen and Oxygen added together?
Answers
Answer:
(a) 1:2
(b) 1:3
Answer:
a) approximately 16:1
The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately 16:1. If we have 2 atoms of each element, the ratio of their masses is approximately 32:2, which reduces to 16:1—the same ratio.
b) The answer is multiple proportion.
When two elements combine to from two or more than two compounds, the weights of one of the element which combine with a fixed weight of the other, bear a simple whole number ratio is the law of multiple proportion and the given example supports the law.
c) If hydrogen and oxygen are mixed together at room temperature, nothing happens. ... Some oxygen and hydrogen atoms combine to form water molecules, releasing a large amount of energy. This energy speeds up more molecules, breaking more bonds and allowing more atoms to react, resulting in the explosion.
