Answer:

pH = 11.7

Explanation:

<u>Given:</u>

[OH-] = 0.00500 M

<u>To determine:</u>

pH of the solution

<u>Explanation:</u>

pH refers to the H+ ion concentration in a given solution whereas pOH indicates the OH- ion concentration.

pH and pOH are related by the following equation:

pH + pOH = 14 ------(1)

Here:

pH = -log[H+]\\\\pOH = -log[OH-]

When OH- = 0.00500 M

pOH = -log(0.00500) = 2.30\\

Based on equation(1):

pH = 14 - pOH = 14 -2.30=11.7

Natasha2012 [34]

The type of nuclear decay in which Oxygen decays to form nitrogen is beta plus decay.

<h3>What is a beta plus decay?</h3>

A beta plus decay is a type of decay in which a proton in an element disintegrates to produce a neutron resulting in a decrease in the atomic number of the radioactive element.

In the given equation below:

  • ^{15}_{7}O \rightarrow ^{15}_{7}N + ^{0}_{1}e

Oxygen decays to form nitrogen due to a decrease in atomic number.

This is an example of beta plus decay.

In conclusion, oxygen decays to form nitrogen beta plus decay.

What would be the molarity of a solution in which 0.56 mole of NaCl is dissolved in enough water to make 2.7 L of solution?
yan [13]

Answer:

Molarity = 0.21 M

Explanation:

Moles <em>solute </em>(mol) = Volume <em>solution</em> (L) x Molarity <em>solution </em>(M)

0.56 mol NaCl = 2.7 L x M

M = 0.2074074074
