Answer:
29.88 g/mol
Explanation:
Lithium has molar mass of 6.94 g/mol and oxygen has weight of 16 g/mol. Since there are 2 lithium, Li would be 13.88 g/mol and 13.88+16=29.88 g/mol
D is the correct answer. Chemical reaction rates won't always be constant, you can change the rate of a chemical reaction. Factors that affect chemical reaction rates would be temperature, the concentration (pressure) of the reactant, or just the general surface area (crushing a reactant would be an example). Solvent polarity can also decrease the rate of a chemical reaction. Therefore, A, B, and C are true, leaving D as the answer.
