Write the molecular formula for a compound with the possible elements C, H, N and O that exhibits a molecular ion at M
liberstina [14]

Answer:

= \mathbf{C_3H_6O}

Explanation:

From the given information, since the molecular mass of the ion M+ is not given;

Let's assume M+ = 58.0423

So, by applying the 13th rule;

we will need to divide the mass by 13, after dividing it;

The quotient n = no. of carbon; &

The addition of the quotient (n) with the remainder r =  no. of hydrogen.

So;

\dfrac{58}{13}= 4 \ remainder \ 6

So;

C_nH_{n+r} = C_4H_{4+6}

= C_4H_{10}

From the given information; we have oxygen present, so since the mass of oxygen = 16, we put oxygen in the molecular formula by removing CH_4. Also, since the mass is an even number then Nitrogen is 0.

So, we have:

= \mathbf{C_3H_6O}

What accounts for the majority of all air pollution? Is that source increasing or decreasing overall?
lianna [129]
Hi there!

One of the main causes of air pollution is smoking.

Smoking affects not only humans, but pets and animals as well. Animals can get cancer too!

Another big cause of pollution is cars. Gasoline of course comes out into the air after it is used. It also affects animals.

A lot of people know that we should change this, but hardly anyone is really doing anything to try and stop it.

I know this is a short answer, but I hope it helps!

Yes, Ionic bonds do not share electrons. Polar covalent bonds share electrons they just share them unevenly due to the polarity.
