1 mole of phosphoric acid (H3PO4) and 1.75 moles of NaOH are added to the one liter water. Calculate the pH.

Chemistry

Marina CMI [18]3 years ago
6 0
Moles of H⁺ released by each mole of acid = 3
Moles of H⁺ released = 3

Moles of OH⁻ released = 1.75

Moles of H⁺ remaining = 3 - 1.75 = 1.25 mol/dm³

pH = -log[H⁺]
pH = -log(1.25)
pH = -0.1

Calculate (a) the number of moles of hydrogen required to react with 0.0969 moles of nitrogen, and (b) the number of moles of am
Bumek [7]

Answer:

The answer to your question is:

Explanation:

Data

moles H=?

moles of N = 0.0969

moles of NH₃=?

                            N₂ (g)  + 3 H₂ (g)  ⇒   2NH₃ (g)

Process

1.- Set a rule of three to calculate the moles of hydrogen

                         1 mol of nitrogen  -------------   3 moles of hydrogen

                         0.0969 moles of N ----------     x

                         x = (0.0969 x 3) / 1

                         x = 0.2907 moles of hydrogen          

2.- Set a rule of three to calculate the moles of ammonia

                        1 mol of nitrogen --------------  2 moles of ammonia

                        0.0969 mol of N --------------   x

                        x = (0.0969 x 2) / 1

                        x = 0.1938 moles of ammonia

Explain why it is harder to remove an inner shell electrons than a valence electron from an atom
VMariaS [17]
<span> It makes sense that an inner shell electron would be tougher to remove than a valence electron because the inner shell electron is closer to the positive nucleus of the atom. Seeing as an electron caries a negative charge it would be too attracted to the positive core to leave readily. Also, the inner shell electrons are constantly repelling electrons outside of it's energy level (however the reason these electrons outside innershell energy levels don't simply fly away is the charge of the positive core overcomes the smaller charges of the comparably negligible inner shell electrons, but that repulsion is still there so keep that in mind) </span>
