Answer:
1.608
Explanation:
According to Graham's effusion law, the rate of effusion (r) of a gas in inversely proportional to the root square of its molar mass (M). The ratio rNH₃ to rCO₂ is:
If CO₂ and NH₃ are allowed to effuse through a porous membrane under identical conditions, the rate of effusion for NH₃ will be 1.608 times that of CO₂.
Answer:
A rock is a naturally occurring solid mixture of one or more minerals or organic matter.
Explanation:
A mineral is naturally formed, inorganic, solid, with a fixed chemical composition, and crystalline structure. A rock at the surface of the Earth would need to be weathered down into sediments.

Answer:
A) The mass would be the same.
Explanation:
Since there is no loss of any particle to vapor during the phase change process from solid to liquid, the mass of the before and after the process will remain the same.
- In this way, the law of conservation of mass is obeyed.
- Mass is the amount of matter contained in a substance.
- Since there is no room for escape or matter loss, the mass will remain the same.
