Answer:

Limited

Explanation:

Once it is used once, it is not reusable. Also, there's a possibility to use ALL the coal there is. That's why it's an unrenewable source, unlike the sun, wind, or water that never ends. Those are renewable

What happens to the chemical identity of a substance during a physical change?
klio [65]
Nothing happens because a physical change only changes the appearance of the substance, whereas a chemical change transforms the substance into something completely different.
i.e. (chemical change) wood + fire = ash
(physical change) wood + axe = smaller pieces of wood

When we react a weak acid with a strong base of equal amounts and concentration, the component of the reaction that will have th
andriy [413]

Answer:

d. the conjugate base of the weak acid

Explanation:

The strong base (BOH) is completely dissociated in water:

BOH → B⁺ + OH⁻

The resulting conjugate acid (OH⁻) is a weak acid, so it remains in solution as OH⁻ ions.

By other hand, the weak acid (HA) is only slightly dissociated in water:

HA ⇄ H⁺ + A⁻

The resulting conjugate base (A⁻) is a weak base. Thus, it reacts with H⁺ ions from water to form HA, increasing the concentration of OH⁻ ions in the solution.

Therefore, the resulting solution will have a pH > 7 (basic).
