K + S = K2S
Potassium reacts with sulfur to produce potassium sulfide
Chlorine-35 and 37 both have the same number of protons. Chlorine-37 has two more neutrons.
hope this helps!

The CaCO3 produced if 47.5 moles of NH3 produced is calculated as follows
CaCN2 +3H2O = CaCO3 + 2NH3
by use of mole ratio between CaCO3 to NH3 which is 1:2 the moles of CaCO3 is therefore = 47.5 /2= 23.75 moles
mass of CaCO3 is therefore = moles x molar mass
= 23.75 moles x 100g/mol= 2375 grams which is approximate 2380 grams(answer 6)
H is 4*10^6 M , OH is 2.5*10^-9 M
