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
Answer:
2.4506 x 
Explanation:
move decimal point to the right 1 time : 24506
24506 becomes 2.4506
count how many numbers after decimal point and that becomes b
b = 4
Answer : The number of moles of
gas added must be, 1.59 moles.
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
The given equilibrium reaction is,

Initial conc. 2.86 x 0 0
At eqm. (2.86-1.30) (x-1.30) 1.30 1.30
The expression of
will be,
![K_{eq}=\frac{[SO_3][NO]}{[SO_2]NO_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BSO_3%5D%5BNO%5D%7D%7B%5BSO_2%5DNO_2%5D%7D)
Now put all the given values in this expression, we get:


Thus, the number of moles of
gas added must be, 1.59 moles.
