1. Energy as particles can't move without kinetic (movement) energy
2. I think it's Diffusion and Active Transport
Answer:
C) an increase in rate of reaction because reactant molecules collide with greater energy
Explanation:
Temperature is one of the factors that affect the rate of a reaction. The rate of a reaction increases with an increase in temperature and vice versa. When the temperature of a reaction increases, the kinetic energy of the reactant molecules increases causing them to react at a faster rate.
The reactant molecules respond to an increase in temperature by colliding at a faster rate due to an increased kinetic energy between the reactant molecules.
I cant really help you but here is a few articles that may help you.

NH4^+ + OH^- ==> NH3 + H2O
<span>Set up an ICE chart. </span>
<span>initial: </span>
<span>NH4^+ = mL x M = 100 x 0.1 = 10 millimoles </span>
<span>NH3 = mL x M = 80 x 0.20 = 16 millimoles. </span>
<span>change: </span>
<span>we add 0.2 g NaOH which is 0.2/40 = 0.005 moles or 5 millimoles. </span>
<span>NH3 = +5 millimoles </span>
<span>NH4^+ = -5 millimoles </span>
<span>equilibrium: </span>
<span>NH3 = 16 + 5 = 21 millimoles. </span>
<span>NH4^+ = 10 - 5 = 5 millimoles. </span>
<span>You may substitute millimoles in place of concn (since millimoles/mL = molarity and the mL (180 mL) appears in both numerator and denominator) OR you can divide millimoles/180 mL to arrive at concn for both base and acid and substitute those numbers. Plug those into the HH equation and solve for pH. </span>
<span>For part d, just set up the HH equation and pH = pKa + log (base/acid). The question is asking you to calculate pH if base and acid were equal. So plug in the same number (any number you choose) for base and acid and calculate. Note that the log of 1 = 0</span>
Answer : The change in energy of an atom is,
Solution : Given,
Wavelength of the photon =
Formula used :
where,
E = energy of an atom
h = Planck’s constant =
c = speed of light =
= wavelength of photon
Now put all the given values in the above formula, we get the energy of an atom.
Therefore, the change in energy of an atom is,
