Answer: Protons

WHY?
Changing electrons will only result in the same element having different charges and hence, changing it's chemical properties.

Changing neutrons will not change an element but it will result in an isotope forming instead. (Isotopes are elements of the same type with different neutron numbers.)

However, changing the proton number would immediately change the nucleus composition, resulting in a change in element with a negative charge as there are more electrons than protons. This results in a expansion in valance electrons's distance from the nucleus. This results in a change in chemical properties of the element.

Therefore, a change in Protons is the answer.

Masteriza [31]

Answer:

B. There is a very large percentage of C-12.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to realize that, since the average atomic mass is 12.01 amu, then the C-12, with an atomic mass of 12.000 am prevails over C-13 with an atomic mass of 13.003 amu as long as the average is nearer to the former.

In such a way, the answer will be B. There is a very large percentage of C-12.

Regards!

How many moles are there in 814.504 g of H2O?
earnstyle [38]
First you need to calculate the molar mass of H2O. To do that, look at the periodic table and add up the AMUs (atomic mass units) 

H = 1.01
O = 16.0 

1.01 • 2 + 16.0 = 18.02 

Next, use stoichiometry to convert grams into moles. To do that, divide 814.504g by the number of grams in one mole of H2O.

814.504 ÷ 18.02 = 45.2 moles 

There are 45.2 moles in 814.504 grams of H2O.
