The mass of 0.125 mol of nitrogen is <br> A 224g<br> B 1.75g<br> C 3.50g<br> D 112g
Vikentia [17]

Answer:C - 3.50g

Explanation:

To solve this problem, nitrogen is a gas and it's always two atoms of it in every reaction.

Using the formula

n = m/ Mm

n - number of mole

m - number of mass

Mm - number of molar mass

n = 0.125 mole

The molar mass of N2 = 14.0067 * 2 = 28.0134g/mol

(N - 14.0067 )

n = mass / molar mass

0.125 mol = mass / 28.0134g/mol

Mass = 0.125 * 28.0134

= 3.501675

= 3.50g

The diagram shows the potential energy changes for a reaction pathway. (10 points)
expeople1 [14]

Answer:

the diagram illustrates an exothermic reaction , because if you look at the graph it starts low than goes high than fall not to far from the top , you can determine how the total change an endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.
