The neutralization reaction among all the reactions would be the one between an acid and a base to produce salt and water.
<h3>What is a neutralization reaction?</h3>
It is a reaction involving an acid and a base to produce salt and water.
From the list of reactions, the only reaction that involves acid and a base with salt and water being the products is the first reaction.
Thus, the neutralization reaction is represented by the equation:

Answer:
B
Explanation:
All organic material has carbon.
Answer: m= 0.69 m or mol/kg
Explanation: Molality is expressed as moles per unit kilograms of solvent or m= n / kg
First convert 25.0 g NaCl to moles
25.0 g NaCl x 1 mole NaCl / 58 g NaCl
= 0.43 moles NaCl
Next convert 625 g H2O to kilograms
625 g H2O x 1 kg / 1000 g H2O
= 0.625 kg H2O
Substitute the values in the formula
m = n / kg
= 0.43 mole NaCl / 0.625 kg
= 0.69 m or mole / kg
Answer:
The procedure for calculating the pH of a solution of a weak base is similar to that of the weak acid in the sample problem. However, the variable x will represent the concentration of the hydroxide ion. The pH is found by taking the negative logarithm to get the pOH, followed by subtracting from 14 to get the pH.
