Answer:
1. they all can be emitted from the nucleus of an atom
2. they have different energies
3. the atom's mass number decreases by 4
4. False
5. have an atomic number greater than 83
6. both choices b and c
7. reduce the overall environmental impact of the waste by consolidating it
8. 2
Explanation:
1. The particles are all sub-nuclei particles
2. The penetrative power comes from different energies. These are known as ionizing energies. Gamma rays are more ionizing than alpha, followed lastly by beta particles
3. The alpha decay decreases the mass by 4. This is because the alpha particle consists of protons 2 and 2 neutrons.
4. The energy is given by the relationship: where m = mass of particle, c is the speed of light.
5. the mass increase is significant, hence a mass greater than 83
6 both b and c will work
7. this reduces the residual radiation
8. the equation needs to be balanced, hence the missing number is 2

Answer:
Explanation:
Let´s consider the following reaction:
CO + Cl₂ ⇒ COCl₂
The general rate law is:
where,
r is the rate of the reaction
k is the rate constant
[CO] and [Cl₂] are the molar concentrations of each reactant
m and n are the reaction orders for each reactant
Since the reaction is first order in CO, m = 1. The overall order is the sum of all the individual orders. In this case, the overall order m + n = 2. Then,
m + n = 2
n = 2 - m = 2 - 1 = 1
The reaction is first order in Cl₂.
The rate law is:
