Volume of 100 drops: 0.43 dL
Explanation:
We can solve this question by applying the rule of three.
In fact, we know that:
- The volume of 1 drop of medicine is 0.43 mL, so the ratio between number of drops and volume (in mL) is 1 : 0.43
- Then we want to find the volume of 100 drops
So we can write the following equation:
where V is the volume of 100 drops.
Solving for V,
And keeping in mind that
1 dL = 100 mL
We can convert into deciliters:

E. Also the equilibrium constant should not have units.
Evaporation
Explanation:
From point C to D, this is a phase change from liquid to gas and it would be depicted by evaporation.
The water cycle presents the transformation of water from one form to another on our planet.
- From Point A to B in which water falls from clouds is a precipitation step.
- Point B to Point C is the step in which surface water runs into lakes.
- Point C to Point D where water turns to gas in the atmosphere is evaporation.
- The from point a D back to A is condensation.
