Answer:

pH = 10.113

Explanation:

Here, we can find pOH first:

pOH = -log([OH^-]) = 3.886.

Then, we can find pH which is 14 - pOH. We then get the answer above.

Consider the reaction, 2 D(g) + 3 E(g) + F(g) => 2 G(g) + H(g) When D is decreasing at 0.15 mol/Ls, how quickly is E decreasi

Answer:

0.023 mol/(L*s).

Explanation:

Equation of the reaction:

2 D(g) + 3 E(g) + F(g) => 2 G(g) + H(g)

Using stoichiometry, 2 moles of D reacts with 3 moles of E and 1 mole of F to give the above products.

1 mole of D will react with 3/2 moles of E.

Delta[D]/delta t = 0.15 mol/L.s

Delta[E]/delta t = (3/2) * 0.15 =

= 0.023 mol/(L*s).

Determine the molecular geometry about the left carbon atom in ch3co2ch3.
Elanso [62]

Molecular geometry about the left carbon atom in CH₃CO₂CH₃ is tetrahedral.

The geometry around left carbon that is CH₃ is tetrahedral.

As the hybridization around left carbon is sp³ that shows its geometry should be tetrahedral and as there are 4 ligands around carbon and there is no lone pair present so the geometry is tetrahedral. So, the molecular geometry about the left carbon atom in CH₃CO₂CH₃ is tetrahedral.
