What would the hydroxide ion concentration be if the hydrogen ion concentration was 1 x 10-3 M?
Sonbull [250]

Answer:

1 x 10⁻¹¹ M

Explanation:

<u>(Step 1)</u>

Determine the pH.

pH = -log[H⁺]

pH = -log[1 x 10⁻³ M]

pH = 3

<u>(Step 2)</u>

Determine the pOH.

pH + pOH = 14

3 + pOH = 14

pOH = 11

<u>(Step 3)</u>

Determine the hydroxide (OH⁻) concentration.

[OH⁻] = 10^-pOH

[OH⁻] = 10⁻¹¹

[OH⁻] = 1 x 10⁻¹¹ M

Consider the following reaction. How many moles of oxygen are required to produce 2.33 moles of water? Assume that there is exce
aleksandr82 [10.1K]
The reaction between <span>C3H7SH and oxygen can be illustrated using the following balanced equation:
</span>C3H7SH (l) + 6O2 (g) --> 3 CO2 (g) + SO2 (g) + 4 H2O (g)
From the balanced equation above, 6 moles of oxygen are required to produce 4 moles of water.
Therefore, to know the number of oxygen moles needed to produce 2.33 moles of water, all you have to do is cross multiplication as follows:
number of oxygen moles = (2.33*6) / 4 = 3.495 moles
