Answer:

Magnesium and calcium belong to the second group i. e. alkaline earth metals. They are known as earth metals because they are extracted from the earth. They are very reactive elements. Their reactivity increases when we go from top to bottom because the outermost electrons goes farther from the nucleus i. e. atomic radius increases so less energy is needed for its removal.

A liquid dietary supplement is packaged in 10-ml dropper containers to deliver 2000 international units of vitamin d3 in each dr
RoseWind [281]

Answer : 37 drops are delivered per milliliter of the solution.

Explanation :

The problem gives us lot of extra information.

We want to find the number of drops delivered in 1 milliliter here.

We have been given that, one drop of the solution delivers 0.027 mL of solution.

Let us use this as a conversion factor, \frac{1 drop}{0.027 mL}

Let us find number of drops in 1 mL using this conversion factor.

1 mL \times \frac{1 drop}{0.027mL} = 37.0 drops

Therefore we can say that 37 drops are delivered per milliliter of the solution.
