Answer:
Macromolecule: polymer
Repeating units: monomer
Simple molecule: monomer
Covalent bonds: both
Explanation:
A macromolecule is a very large molecule commonly created by the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more.
A monomer is a molecule that can be reacted together with other monomer molecules to form a larger polymer chain.
Polymers include bounds between nonmetal atoms, therefore, they are joint by covalent bonds
The correct option is A)
They overlap to form a pi bond

The answer is:
The rate constant K2 = 1.9 x 10^-4 1/s
The explanation:
According to Arrhenius equation:
ln(k₁/k₂) = Ea/R (1/T₂ - 1/T₁)
when K is the rate constant
and Ea is the activation energy
R is the ideal gas constant
T1 & T2 is a temperature at kelvin
when we have:
Ea = 272 KJ = 272000 J
R is the ideal gas constant 8.3145 J/Kmol
K1 = 2.3 x 10^-5 1/s K2 = ?? that is we need to calculate
T1 = 718 K T2 =753 K
So by substitution:
ln(k₁/k₂) = Ea/R (1/T₂ - 1/T₁)
㏑(2.3X10^-5/K2) = [272000/8.314](1/753-1/718)
∴ K2 = 1.9 x 10^-4 1/s
A neutron has a charge of 0, as it is neutral.
