The molarity = 0.454 M
<h3>Further solution</h3>
Given
Volume = 3 L of solution
mass = 140 g of NaBr
Required
The molarity
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
mol of NaBr :
= mass : MW
= 140 g : 102,894 g/mol
= 1.361
Molarity :
= 1.361 mol : 3 L
= 0.454 M
Answer is: more H⁺ ions than OH⁻ ions.
<span>An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or
protons.
For example, hydrochloric acid dissociate in aqueous
solution to form hydrogen ions (H</span>⁺)
and chloride anion (Cl⁻):<span>
HCl(aq) → H</span>⁺(aq) + Cl⁻<span>(aq).

An Arrhenius base is a
substance that dissociates in water to form hydroxide ions (OH⁻<span>).
For example lithium hydroxide is an Arrhenius base:</span>
LiOH(aq) → Li⁺(aq) + OH⁻(aq).
Answer:
J electrons
Explanation:
Electrons are the negatively charged subatomic particles that surrounds the nucleus of an atom.
- Electrons occupy the bulk volume of an atom.
- These particle was discovered by J.J Thomson
- They found orbiting the extra-nuclear space of every atom.
- The nucleus is made up of protons and neutrons.
