Answer:
It’s true
Explanation:
If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system. ... The Law of Conservation of Mass holds true because naturally occurring elements are very stable at the conditions found on the surface of the Earth.
The law of conservation of mass states energy can’t be created or destroyed, but can be interconverted. During those processes, you are not creating new molecules, but each molecule undergoes a mechanism to be converted to another.
Throwing isn't classified as a force so I'd say C but it is a force just not a type
Answer:
It is one single unit which is repeated in a polymer
Answer:
100g/cm^3
Explanation:
density=mass/volume
convert mass in kg to g
1kg=1000g
5kg=5000g
therefore, density=5000g/50cm^3
=100g/cm^3
