I analyze one atom of carbon in a rock and then one atom of carbon from one of my skin cells. Explain the differences I might se
fgiga [73]

Answer:

Explanation:

The two carbon atoms would be different. These different carbon isotopes are called isotopes. Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass number due to the difference in the number of neutrons in their various nuclei.

Carbon for example has 3 known isotopes which are:

                    ¹²₆C         ¹³₆C         ¹⁴₆C

These isotopes have different places in nature where they can be found. Some can occur together naturally.

Isotopes have the same chemical properties because they share similar electronic configuration.

Using the balanced equation N2+O2=2NO, how many grams of NO can be produced when 25.0 grams of N react?
Oxana [17]

Answer:

53.55gNO

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is possible for us to calculate the produced grams of nitrogen monoxide by starting with 25.0 g of nitrogen via their 1:2 mole ratio and the molar masses of 30.1 g/mol and 28.02 g/mol, respectively and by some stoichiometry:

=25.0gN_2*\frac{1molN_2}{28.02gN_2}*\frac{2molNO}{1molN_2}*\frac{30.01 gNO}{1molNO}\\\\=53.55gNO

Best regards!
