The combustion of fuels containing sulfur leads to the production of acid rain
answer
True
question
sulfur oxides form acid solutions in water.
answer
True
question
At the same temperature and pressure, 1 L of hydrogen gas and 1 L of neon gas have the same mass
answer
False. Not true because =moles doesn't mean =mass
question
equal volumes of ideal gases at the same temperature and pressure contain the same number of moles.
answer
True. According to the ideal gas law ( P V = n R T), if P, V, and T are the same for two different gases, then n (the number of moles) must be the same.

question
CO2
answer
It can be prepared by the action of acid on limestone. It is used to extinguish fires. It dissolves in water at room temperature. It sublimes rather than melts at 20 degrees C and 1 atmosphere pressure.
