PLEASE HELP WITH CHEM !! Calculate the [OH-] of each of the following solutions given the [H+]. AND Classify each of the solutions in the question above as either acid, base, or neutral. AND FIND THE PH

Answers

pH, pOH, [H+], and [OH-] are all interrelated. For simplicity, we assume that we're working with aqueous solutions at 25 °C.

The following mathematical relations are relevant here:

pH = -log[H⁺]pOH = -log[OH⁻][H⁺] = 10^-pH[OH⁻] = 10^-pOHpH + pOH = 14[H⁺] × [OH⁻] = 10^-14

A pH of 7 is neutral; a pH less than 7 is acidic; and a pH greater than 7 is basic.

---

We are given four solutions of varying [H⁺], and we want to find the pH and the [OH⁻]. The pH will tell us whether the solution is neutral, an acid, or a base.

Finding the [OH⁻]

Using the relationship [H⁺] × [OH⁻] = 10^-14, we can calculate the [OH⁻] of each solution by dividing 10^-14 by the given [H⁺]:

[OH⁻] = 10^-14/(3.3 × 10^-5) = 3.0 × 10^-10

[OH⁻] = 10^-14/(4.0 × 10^-8) = 2.5 × 10^-7

[OH⁻] = 10^-14/(7.2 × 10^-11) = 1.4 × 10^-4

[OH⁻] = 10^-14/(8.2 × 10^-4) = 1.2 × 10^-11

Note: While not indicated here, the units for [H⁺] and [OH⁻] are moles/liter (M).

Finding the pH

To find the pH of each solution, we take the negative logarithm of the [H⁺] with base 10, i.e., pH = -log₁₀[H⁺]:

pH = -log(3.3 × 10^-5) = 4.48

pH = -log(4.0 × 10^-8) = 7.40

pH = -log(7.2 × 10^-11) = 10.14

pH = -log(8.2 × 10^-4) = 3.09

Note that, for significant figures involving logarithms, the number of decimal places should equal the number of significant figures in the argument of our logarithm (the argument is what we're taking the -log of). Since we're taking the -log of quantities given to two significant figures, our corresponding pH values are given to two decimal places.

Acid, Base, or Neutral?

As mentioned above, a pH = 7 is neutral, a pH < 7 is acidic, and a pH > 7 is basic.

4.48 < 7, so the first solution is an acid.

7.40 > 7, so the second solution is a base.

10.14 > 7, so the third solution is a base.

3.09 < 7, so the fourth solution is an acid.

Continue reading from Ruby Bridges’s autobiography.

We drove down North Galvez Street to the point where it crosses Alvar. I remember looking out of the car as we pulled up to the Frantz school. There were barricades and people shouting and policemen everywhere. I thought maybe it was Mardi Gras, the carnival that takes place in New Orleans every year. Mardi Gras was always noisy.

As we walked through the crowd, I didn’t see any faces. I guess that’s because I wasn’t very tall and I was surrounded by the marshals. People yelled and threw things. I could see the school building, and it looked bigger and nicer than my old school. When we climbed the high steps to the front door, there were policemen in uniforms at the top. The policemen at the door and the crowd behind us made me think this was an important place.

It must be college, I thought to myself.

Savvas Realize. Investigation 8 Experiment 1

Answers

Answer:

–1065.25 KJ of energy.

Explanation:

From the question given above, the following data were obtained:

4FeO + O₂ —> 2Fe₂O₃  ΔH = –560.66 kJ

From the balanced equation above,

The formation of 2 moles of Fe₂O₃ released –560.66 kJ of energy.

Finally, we shall determine the amount of heat energy released when 3.8 moles of Fe₂O₃ are produced. This can be obtained as follow:

From the balanced equation above,

The formation of 2 moles of Fe₂O₃ released –560.66 kJ of energy.

Therefore, the formation of 3.8 moles of Fe₂O₃ will release

= (3.8 × –560.66)/2 = –1065.25 KJ of energy.

Thus, –1065.25 KJ of energy is released from the reaction.

Answers

Answer:

[H⁺] = 4.56x10⁻³ M

pH = 2.34

Explanation:

Hello there!

In this case, according to the ionization reaction of benzoic acid:

[tex]HC_6H_5CO_2+H_2O\rightleftharpoons C_6H_5CO_2^++H_3O^+[/tex]

Whereas [tex][H_3O^+]=[H^+][/tex], we can set up the equilibrium expression in terms of [tex]x[/tex] (reaction extent) to obtain:

[tex]Ka=\frac{[C_6H_5CO_2^-][H_3O^+]}{[HC_6H_5CO_2]} \\\\6.5x10^{-5}=\frac{x^2}{0.32-x}[/tex]

However, since Ka<<<1, we can neglect the [tex]x[/tex] on bottom to easily solve for it:

[tex]6.5x10^{-5}=\frac{x^2}{0.32}\\\\x=\sqrt{6.5x10^{-5}*0.32} \\\\x=4.56x10^{-3}[/tex]

Which is actually the same as [H⁺]. Finally, the pH turns out to be:

[tex]pH=-log(4.56x10^{-3})\\\\pH=2.34[/tex]

what is the limiting reactant of 20.0 moles of o2 react with 30.0 moles of h2 according to the following reaction ? 2H2 + O2 = 2H2O

Answers

Answer:

The limiting reactant is hydrogen.

Explanation:

According to the balanced equation for synthesis of water, hydrogen is used up twice as fast as oxygen -- we need two moles of H2 for every one mole of O2 when creating water.

Since we have 20 moles of oxygen, this means we would need twice as much hydrogen, or 40 moles, to use it all up. There is only 30 moles of hydrogen, which means that all the hydrogen will be used before the 20 moles of oxygen is used. Hydrogen limits production in this case.

We have that
