The answer if calculated correctly, is 12.

The answer should be 12 since 4 x 3 = 12

This is because ammonia is NH^3 and if it has a number before it you multiply it with the rest of the chemical equation.

I hope this helps

Diamond has a density of 3.513 g/cm³. The mass of diamonds is often measured in "carats," where 1 carat equals 0.200
Gennadij [26K]

The volume of a 1.86-carat diamond in cubic centimeters is 0.106 cm³

Given,

The density of a diamond is  3.513 g/cm³.

We have to find out the volume of a 1.86-carat diamond in cubic centimeters.

Convert the units of the diamond from carat to grams, we have:

(1.86 carats) x (0.200 g / 1 carat) = 0.372 g

The volume of the diamond is obtained by dividing the mass by the density, therefore using the formula, we get

                            v = m / d

                            v = 0.372 g / (3.51 g/cm³) = 0.1059 cm³

                       or, v = 0.106 cm³ (approx)

Therefore, the volume of a 1.86-carat diamond is approximately 0.106 cm³.

When you combine chocolate powder and milk, the result is best describe as?
NeX [460]
Answer:

The answer to your question would be substance, but chocolate power mixed into milk would be more of a suspension.

Explanation:

Neither chocolate powder nor milk are elements. They are both complex molecules. Their mixture will not result in the formation of a compound since no chemical reaction will take place.

The molecules of the chocolate powder will simply intermingle with the fatty molecules of the milk to form the substance.

When thoroughly mixed the solution will become homogeneous so there will be no lumps of chocolate power visible. But after time, the chocolate will become visible at the bottom of the clear container in which we asked you to prepare the mixture.

HOPE THIS HELPS :)
