The one property that you can always depend on to change vapor pressure is temperature. So as the water's temperature increases so does the vapor pressure. The warmer the water, the higher the vapor pressure.

Blank one: Hot water

Blank Two: Temperature

Answer: The <em>hot water</em> puddle has the highest vapor pressure because vapor pressure depends on<em> temperature.</em>

Explanation:

Vapor pressure of the liquid is defined pressure exerted by the vapors of the liquid on its liquid surface. It increases with increase in temperature and vice-versa. And it also depends upon surface area of the liquid.

A medium puddle with hot water will have maximum vapor pressure because the hot water has higher temperature from the remaining other two puddles.

Calcium must lose two electrons to get a full outer shell. what is the name of the group to which calcium belongs
11111nata11111 [884]
The answer to this question would be: alkaline earth metal

Alkali earth metal is the second column group of the periodic table. In this group, the element has 2 extra electrons in their outer cells. That is why most of this metal has 2+ charge.
Their neighbor is the alkali metal which was the first column of the periodic table. The name is similar so don't confused and mix them each other.

Suppose we have two rock samples, A and B. If rock A was subject to both physical and chemical weathering while rock B was subje
hammer [34]

Answer:

Rock A because after physical weather and chemical weathering it more likely for Rock A to experience more chemical weathering.

Explanation: Weathering: This is a geological term used to describe the various processes and Activities involved in the breaking down of rocks either through physical,mechanical,chemical etc actions into smaller particles.

ROCK A WILL HAVE MORE CHEMICAL WEATHERING BECAUSE THE PHYSICAL WEATHERING MUST HAVE BROKEN DOWN THE PARTICLES FOR EASY WATER AND OTHER SUBSTANCE NEEDED FOR EASIER CHEMICAL REACTION OR WEATHERING.

Which action would shift this reaction away from solid calcium fluoride and toward the dissolved ions? which action would shift
ANTONII [103]
Hello!

The chemical reaction for the dissolving of calcium fluoride is the following:

CaF₂(s) ⇄ Ca⁺²(aq) + 2F⁻(aq)

In this reaction, and according to Le Chatelier's principle, the action that would shift this reaction away from solid calcium fluoride and towards the dissolved ions is the removing of fluoride ions.

Le Chatelier's principle
states that in an equilibrium reaction, the system would shift in the opposite direction of the changes. If we remove fluoride ions from the system, it will shift towards the formation of more fluoride ions by dissolving more Calcium Fluoride to achieve equilibrium again.

Have a nice day!
