<u>Answer:</u> The correct answer is Option c.

<u>Explanation:</u>

To calculate the percentage composition of an element in a compound, we use the formula:

\text{Mass percent of element}=\frac{\text{Mass of element in compound}}{\text{Mass of the compound}}\times 100

We are given:

Molar mass of N_2O = 44.013 g/mol

Mass of nitrogen in compound = [2\times 14.0067]=28.0134g/mol

Mass of oxygen in compound = 15.999 g/mol

By putting and calculating the mass percentages of nitrogen and oxygen, we get:

\text{Mass percent of nitrogen}=\frac{28.0134g/mol}{44.013g/mol}\times 100=63.64\%

\text{Mass percent of oxygen}=\frac{15.999g/mol}{44.013g/mol}\times 100=36.36\%

Hence, the correct answer is Option c.

During the phase change from solid ice to liquid water, which bonds/forces are being weakened?
kvasek [131]
INTERmolecular forces (such as dipoles and London dispersion forces).

The actually compound isn't changing (it's still H2O in solid or liquid form), so INTRAmolecular bonds aren't being affected. It's just the strength of attraction between separate molecules that is weakening.

If an atom of the following element had a neutral charge, how many electrons would it have?
Yakvenalex [24]

Answer:

31

Explanation:

In order for an atom to have a neutral charge, it needs to have the same number of protons and electrons. You can see by the illustration that the atomic number is 31, so this element has 31 protons. Knowing that, we also know that it must have 31 electrons to be neutral.
