I think it shows how the temperature of a substance changes when heated
<u>Answer:</u> The percentage yield of 
is 90.26%.
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of 
= 80 g
Molar mass of = 100 g/mol
Plugging values in equation 1:
For the given chemical equation:
By the stoichiometry of the reaction:
If 1 mole of produces 1 mole of
So, 0.8 moles of will produce = 
of
Molar mass of = 44 g/mol
Plugging values in equation 1:
The percent yield of a reaction is calculated by using an equation:
......(2)
Given values:
Actual value of = 35.2 g
Theoretical value of 
= 39 g
Plugging values in equation 2:
Hence, the percentage yield of is 90.26%.
It occurs when nucleus has too many protons or too many neutrons that can be transformed into the other. With beta minus decay, neutron decays can turn into a proton, an electron, and an antineutrino.
Non metals and metollids in periodic tables are the same how this helps ;)
Using the ideal gas equation pV = nRT, where R is the ideal gas constant, we can show that p=nRT/V. Since n, R and T are all constants, p2/p1 = V1/V2 where p1 and p2 are the start and final pressures respectively and V1 and V2 are the start and final volumes respectively. For if p1 = 3*p2, the pressure would have fallen to one third of its original value, and it follows that V2 = 3*V1. Therefore, for the pressure to fall to a third of its original value, the volume must increase by a factor of 3.
