Answer:

8

Explanation:

From the question given above, the following data were obtained:

Empirical formula = C₅H₇

Molecular weight = 537 amu.

Number of empirical unit (n) =?

We can obtain the number of empirical units in the actual molecular formula by doing the following:

[C₅H₇]n = 537

[(12×5) + (1×7)]n = 537

[60 + 7]n = 537

67n = 537

Divide both side by 67

n = 537/67

n = 8

Thus, there are 8 empirical units in the molecular formula

Luis is helping his parents paint a border around the walls of a room. He uses a stencil to repeat the same design on each wall
iren [92.7K]

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).
