The catalyst would increase the rate of the forward reaction...
And increase the rate of the backward to the same extent thus not affecting equilibrium.
The number of particles that are in 12.7 moles of compound that Jessica had is 7.65 x10^24 particles of compound ( answer E)
<u><em>Calculation</em></u>
<u><em> </em></u>The number of particles are calculated using the Avogadro's Principle constant.
- that is according to Avogadro's 1 moles = 6.02 x10^23 particles
what about 12.7 moles of compound= ? particles\
by use of cross multiplication
- number of particles of compound= [12.7 moles x (6.02 x 10^23)] / 1 mole = 7.65 x 10^24 particles of compound ( answer E)
N.b moles and moles cancels each other
Answer: 1:The bowling ball have more gravitational potential energy as it sit on top of the building
Explanation:
Answer: pH = 2.68
Explanation: pH = - log[H3O^+] .
HCl reacts with water : HCl + H2O -> Cl^- + H3O^+
So [H3O^+] = c(HCl) = 0.0021 M
pH = - log(0.0021) = 2.68
