I don’t understand this one sorry
Answer:
Polymerization.
Explanation:
Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.
Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.
In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.
Polymerization is given by the chemical formula;
nA -----> A(n).
In this scenario, Luis uses a stencil to repeat the same design on each wall to form one long grapevine with a bunch of grapes every foot along its length.
Hence, the type of chemical reaction this best model is polymerization because it involved repeating the same design (monomers) to form a long grapevine with a bunch of grapes (polymers).
The capacity to do work is said to be energy. It is a quantitative property and conserved quantity. It can exist in different forms such mechanical energy, sound energy, chemical energy etc. According to law of conservation of energy, energy can neither be created nor be destroyed implies there is no loss of energy occurs during any process or any reaction only conversion of energy takes place.
Temperature and pressure are not forms of energy, they are physical properties.
Hence, first option (1) is the correct answer i.e. chemical, mechanical, electromagnetic are three forms of energy.
Answer: 0.123 M
Explanation:
According to the neutralization law:
where,
= molarity of 
solution = ?
= volume of solution = 15.00 ml
= molarity of 
solution = 0.100 M
= volume of solution = 18.44 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of the unknown HBr solution is 0.123 M
