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.
Answer:
True
Explanation:
The force gets weaker as you move further away from the nucleus. Therefore, the electrons in the outermost energy level have the most energy
Answer:The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
Explanation:
Answer:
1 g/cm3
Explanation:
The formula for density is mass/volume
The mass is 100 g and the volume is 100 cm3
100 g/100 cm3=1 g/cm3
