Answer:Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.
Explanation:
Answer: Yes the absorb in the visible range.
Explanation:
The relationship between wavelength and energy of the wave follows the equation:
where,
= energy of the wave = 182 kJ/mol = 182000 J/mol
N = avogadro's number =
h = plank constant =
c = speed of light =
= wavelength of the wave = ?
Putting all the values:

The wavelength range for visible rays is 400 nm to 750 nm, thus the complex absorb in the visible range.
Answer:
In this experiment, the period of the pendulum is the dependent variable. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string.
