Answer:
Yes, it's an exothermic reaction, which means that energy is being released, thus it is a chemical reaction.
Explanation:
The chemical symbol for sodium is Na
Answer:
The molecules of ammonia will effuse 1.28 times faster than carbon monoxide.
Explanation:
The kinetic molecular theory tells us that
Vrms = √(3RT/MW) where vrms is the root mean square velocity of an ideal gas
So vrms is inversely proportional to MW and so will be the rate of effusion. Comparing ammonia and co we have:
rate (NH3)/rate(CO) = √MWCO/√MWNH3 = √28.01/√17.03 = 1.28
rate(NH3) = 1.28 rate CO
