When calcium metal (Ca) reacts with oxygen gas (O2), it produces the ionic compound calcium oxide (CaO). Write the balanced equation for this reaction. Then, explain if this process meets the requirements to be considered a redox reaction.

The balanced equation for this ionic compound is 2Ca + O2 -> 2CaO. This reaction is an oxidation-reduction reaction because the electrons are transferred between two species, and Calcium is  oxidized from the oxidation state 0  to 2+ while oxygen is reduced from oxidation state 0 to 2, -meeting the requirement to be a redox reaction.

(i just took the test and this is the answer i came up with, i hope it is helpful)

:D

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
