Acc. to Law of Conservation of Mass
Mass of reactants=Mass of Products
Let mass of Oxygen be x.
So,
50.6+x=452
x=452-50.6
=401.4 g
There are several ways to give an object potential energy. One can move the object against the force of gravity to increase. One can also stretch an object out or put pressure on it.

Transparency (also called pellucidity or diaphaneity) in the field of optics is the physical property of allowing light to pass through the material without significant light dispersion.
Explanation:
A property which does not bring any change in chemical composition of a substance is known as physical property.
For example, blood is more viscous than water, its pH is slightly alkaline, its temperature is about
(
) .
On the other hand, a property which changes chemical composition of a substance is known as a chemical property.
For example, precipitation, reactivity, toxicity etc are chemical property.
Sometimes, the change in color of a substance can also occur due to a chemical change.
Thus, we can conclude that following are the physical characteristics of blood.
- it is more viscous than water.
- its temperature is about
(
).
- the pH is slightly alkaline.
- it is about 8% of one’s total body weight.
