Answer:
Kp = 2.2 x 10-2
Explanation:
The equation for the decomposition of NH3 is as follows:
2NH3(g) <-------------> N2(g) + 3H2(g)
Initially only NH3 present
PNH3 = 2.3 atm
at equilibroum
PH2 = 3 x PN2 = 0.69 atm;
Therefore;
PN2 = 0.69 atm/3
= 0.23 aatm
PNH3 = 2.3 - 2(0.23) = 1.84 atm
Kp = (PN2) (PH2)3 / (PNH3)2
Kp = (0.23) (0.69)3 / (1.84)2
Kp = (0.23) (0.33) / (3.39)
Kp = 0.6912 / 1.44
Kp = 0.0224
Kp = 2.2 x 10-2
Feromones, used by almost all mammals apart from humans
Answer:
Explanation:
Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers. Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms
Combustion of <span>acetylene :
</span><span>molar ma</span>ss acetylene ( C₂H₂ ) = 26.0 g/mol and CO₂ = 44.0 g/mol
<span>
2 C₂H₂ + 5 O₂ ---> 4 CO₂ + 2 H₂O
</span>
2 moles C₂H₂ --------> 4 moles CO₂
? moles C₂H₂ --------> 1.10 moles CO₂
moles C₂H₂ = 1.10 * 2 / 4
moles C₂H₂ = 0.55 moles of C₂H₂
Mass acetylene:
m = n * mm
m = 0.55 * 26.0
m = 14.3 g
