Answer:
The answer to your question is: They are stronger than those in water.
Explanation:
When a substance is heated, heat is breaking forces among molecules like hydrogen bonds, london forces, van der waals forces, etc, if a substance has a lot of these forces, the boiling point will be higher because more forces must be broken.Then, glycerol must have stronger forces than those of water.
<em>Answer:</em>
- The molarity of ammonia will be 2.88 M.
<em>Chemical equation</em>
HCl + NH3 ------> NH4Cl
First of calculate the moles of HCl
mole of HCl = Molarity × Vol (L)
mole of HCl = 0.800× 0.018 = 0.014 mole
As the in balance chemical, moles of HCl and NH3 areequal
so
moles of NH3= 0.014
Molarity of NH3 = moles ÷ V(L) = 0.014/0.005 = 2.88 M
<em>Result</em>:
- The molarity of ammonia will be 2.88 M.
D: The atomic mass number
D. Electrons
Atoms can share their electrons in order to create bonds with other atoms
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
