Answer:
Lavoisier made an important contribution to chemistry by the law of conservation of mass
Explanation:
The law of conservation of mass tell us, that the mass doens't change in a system. You have the same mass at the begining and in the end of a reaction.
Matter is neither created, nor destroyed in a chemical reaction.
This law also states that mass of reactants is the same of products in any chemical reaction
The speed of sound at 20 oC in air is 343 m/s.
The speed of sound in helium at 20 oC is 927 m/s.
The speed of sound in natural gas (methane) at 20 oC is 446 m/s.
Explanation:
- The speed of sound depends upon the density and elasticity of gas.
- The speed of sound is the distance which is traveled per unit time by a sound wave as it goes through an elastic medium.
- The speed of sound in gas depends only on its temperature and composition.
- Also the speed of sound refers to the speed of sound waves in air.
- Air IS 343 m/s
- Helium is 927 m/s.
- Natural gas (methane) is 446 m/s.
