Balanced chemical equation:
2 C2H2 + 5 O2 = 4 CO2 + 2 H2O
2 moles C2H2 ---------------- 5 moles O2
moles C2H2 ------------------ 84 moles O2
moles C2H2 = 84 * 2 / 5
molesC2H2 = 168 / 5 => 33.6 moles of C2H2
Chlorine, Anthax is a biological agent, and uranium is a radioactive agent, and dynamite is just a no. Chlorine is a chemical gas.
Endpoint . this is when the color of the indicator changes while equivalence is when added titrant is chemically equivalent completely to the analyte sample
As we know, Number of protons = Atomic Number
So,
And, Atomic mass = Number of protons + Number of Neutrons (N)
therefore ~
Number of Neutrons = 19
