The correct answer is the third option. Particulate matter is the air pollutant known to affect people with a heart disease. According to research, this pollutant is associated with an increased risk of cardiovascular diseases.
One molecule of water contains two atoms of hydrogen and one atom of oxygen, the atomicity of water is three.
2C3H8+ 702--->6CO2+8H20
FROM Equation above 2 moles of C3H8 reacted with 7 moles of oxygen to form 6 moles of c02 plus 8 molesof H2O
the moles of c3H8 reacted is = MASS/ R.F.M
THE R.F.M =48+8=44
Number of moles is hence 0.025/44=5.68x10^-4
since ratio of C3H8 to O2 is 2:7 Therefore moles of O2 reacted is 1.989 x10^-3
mass= r.f.m x number of moles
(1.989x10^-3) x 32 =0.064g
Answer:
KCI is the salt and KOH is the base
