Answer:
Its when like two pure substances are like combined into one.
Explanation:
According to newtons law every action has a equal reaction therefore it will push back 200n aswell
E=mc (square) E= mass times capacity squared
Chlorine will have the slowest rate of diffusion because it has the highest relative molecular mass of 71 followed by O₂ with 32, then Neon 20 then He with 2
The rate of diffusion of a gas is inversely proportional to the square root of its relative molecular mass.
