Answer:

molar mass CO = 28.01 g/mol

3.45 x 10^2 x 28.01 =9.66 x 10^3 g

mass Zn = 2.45 x 10^-2 x 65.39 g/mol=1.60 g => 1.60 x 10^0

Which pair of elements are the most different

siniylev [52]

After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. the decay that is present is gamma decay because gamma decay has photons which has no mass unlike alpha and beta decay.

Why is it possible to collect hydrogen gas over water?

maw [93]

A gas produced in a chemical reaction can be collected by water displacement. Because the gas is collected over water, it is not pure but is mixed with vapor from the evaporation of the water. Dalton's law can be used to calculate the amount of the desired gas by subtracting the contribution of the water vapor.
