Volume Mass Problem: Ammonia and gaseous hydrogen chloride combine to form ammonium chloride:
NH3(g) +
NH4Cl (s)
HCI (6)
What mass of Ammonium Chloride at 25.0 degrees Celcius and 760. Torr will form if you combine 4.21 L
of Ammonia with hydrogen chloride?

Calculate the mass percent of hydrogen in methyl acetate

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.
