why is the reaction between potassium (k) and chlorine (cl) considered an oxidation-reduction reaction?

k(s) + cl2(g) → 2kcl(s)

chlorine reduces in size when it reacts with potassium.
chlorine takes electrons from potassium in the reaction.
potassium reduces in strength when it bonds with chlorine.
potassium takes chlorine's place in the reaction.

For the following, determine the type of reaction and then give products.

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.

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
