Which coefficient before sodium bromide (NaBr) balances this chemical equation?

Chemistry
1 answer:
yuradex [85]3 years ago
8 0

We see that in the left-hand side of the equation, the side of the reactants, that we have 2 moles of Na and bromine is in it's diatomic form.

Therefore, we have 2 moles of each of these elements. When we combine the sodium bromide molecule in the products, we are going to want to keep these molar amounts the same. So we are going to need to put a 2 in front of the sodium bromide in order to correctly balance this equation.

So the coefficient for sodium bromide (NaBr) in this equation is 2.

At what volume of added acid is the phph calculated by working an equilibrium problem based on the initial concentration and kbk
nikdorinn [45]

In an acid-base neutralization reaction, the equilibrium reaction would be between a weak base and its conjugate strong base. So, this must be the basis of the volume of added base.

<h3>What is pH ?</h3>

pH is used to measure whether the substance is acidic, basic or neutral and the range is 0 - 14.

<h3>What is Neutralization Reaction ? </h3>

Neutralization reaction is a chemical reaction in which an acid and a base react quantitatively with together.

Neutralization reaction equation:

Acid + Base → Salt + Water

Thus from the above conclusion we can say that In an acid-base neutralization reaction, the equilibrium reaction would be between a weak base and its conjugate strong base. So, this must be the basis of the volume of added base.

What is the ph of a 3x10-8M H+ solution
Lelu [443]

Answer:

The pH of the solution is 7, 52

Explanation:

The pH gives us an idea of the acidity or alkalinity of a solution. Is calculated:

pH = -log (H +)

pH= -log ( 3x10-8)= <em>7, 52</em>
