Answer:

For isotopes, the difference between the mass number and number of neutrons is constant.

Explanation:

Isotopes are atoms with the same atomic number but different mass numbers.

Number of neutrons in an atom can be obtained by subtracting the atomic number from the mass number.

So in other words , isotopes are atoms for which the difference between the mass number and number of neutrons is constant.

For example, Hydrogen,Deuterium and Tritium are isotopes of Hydrogen in which the difference between mass number and number of neutrons is 1.

What inspired Mendeleev to create his organization for the elements
const2013 [10]

Dimitri Mendeleev was inspired primarily by the work of Antoine Lavoisier and his work on writing the first extensive list of known elements.

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).
