When an ionic compound dissolves in water, the ions are held to the water molecule due to
a. an ionic bond.
b. a covalent bond.
c. an attractive force.

Write a net ionic equation to show that hydrofluoric acid, behaves as an acid in water.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
