False.
Protons have a charge of +1 and neutrons are neutral.
This would be true if neutrons was replaced with electrons.
Answer:
Its Experimental

the others don't make sense
Answer:
the number of neutrons and protons in an atom
HA in the graph represents a weak acid.
<h3>Explanation</h3>
Is HA an acid or a base?
Apply the Arrhenius Theory of Acids and Bases.
- Acids ionize in water to produce (or equivalently ) and a conjugate ion.
- Bases ionize in water to produce and a conjugate ion.
The equation in the picture shows that HA ionizes in water to produce ions. By the Arrhenius Theory of acids and bases, HA is an acid.
Is HA a weak acid or a strong acid?
Both weak and strong Arrhenius acids ionize in water to produce (or equivalently ) and a conjugate ion. However,
- Strong acids ionize completely. There would be nearly no acid left in the solution. Expect arrows ⇒ in only one direction in the equation.
- Weak acids also ionize, but only partially. There would be plenty of acid left in the solution. Expect two-sided arrows like ⇔ and two-sided harpoons like in the equation.
As seen in the bar chart, there are plenty of HA left after ionization. HA ionizes only partially. Also, the equation shows a two-sided arrow. As a result, HA is a weak acid.
