Answer:
Explanation:
Reactants
Magnesium = 24.3 g
Hydrogen chloride= x g
Products
Hydrogen gas = 2.04 g
Magnesium chloride = 96.9 g
As the mass of the reactions is conserved we have
Mass of reactants = Mass of products
Mass of hydrogen chloride is .
Answer:
c. HF can participate in hydrogen bonding.
Explanation:
<u>The boiling points of substances often reflect the strength of the </u><u>intermolecular forces</u><u> operating among the molecules.</u>
If it takes more energy to separate molecules of HF than of the rest of the hydrogen halides because HF molecules are held together by stronger intermolecular forces, then the boiling point of HF will be higher than that of all the hydrogen halides.
A particularly strong type of intermolecular attraction is called the hydrogen bond, <em>which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond</em>, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.
the answer is D
Because x can equal any number divided by 2 +1
True because usually when you add stufff to a solution it increases
