Answer:

d. the conjugate base.

Explanation:

The general reaction of a weak acid, HA, with a strong base YOH, is:

HA + YOH → A⁻ + H₂O + Y⁻

<em>Where A⁻ is the conjugate base of the weak acid and Y⁻ usually is a strong electrolyte.</em>

<em />

That means after he complete reaction you don't have weak acid nor strong base, just conjugate base that will be in equilibrium with water, thus (Strong electrolyte doesn't change pH:

A⁻ + H₂O ⇄ HA + OH⁻

As the equilibrium is producing OH⁻, the pH of the solution is being affected for the conjugate base

Right option:

<h3>d. the conjugate base. </h3>

Stalactites and stalagmites form as ________ precipitates out of the water evaporating in underground caves.
Fittoniya [83]

Stalactites and stalagmites form as ________ precipitates out of the water evaporating in underground caves.

Group of answer choices

hydrochloric acid

sodium bicarbonate

calcium carbonate

sodium chloride

sodium hydroxide

Answer:

calcium carbonate

Explanation:

A stalactite is an icicle-looking mould that is formed by the precipitation of natural minerals as a result of water dripping from the ceiling, hanging from a cave.

A stalagmites in the other hand, grows upwards and is also a mound that is formed by the deposits of minerals gotten by the water dripping on the floor of a cave.

Therefore, stalactites and stalagmites form as calcium carbonate precipitates out of the water evaporating in underground caves.

We consider a spherical air bubble rising through a water tank. The pressurepinside the bubble isequal to its surrounding pressu
DENIUS [597]

The answer is a change in internal energy causes work to be done and heat to flow into the system.  

<u>Explanation:</u>

Boyle's law says, PV=RT

  • Here P represents the pressure, V represents the volume and T represents the temperature. R is a constant. The volume of an ideal gas is inversely proportional to its pressure if the temperature is constant.
  • When a bubble is present in deep water it has water pressure and atmospheric pressure. Then the Volume increases when water pressure raises which is proportional to the depth reduces.
  • But we should not finalize the volume of the bubble will be four-time as great as at the top than the bottom.  if the bottom of the lake is at four atmospheres, the temperature will not be equal to the top.
  • If the bubble travels from the bottom to the top or vice-versa, it's going to lose or gain heat in a way that must be quite hard to measure.
