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).

Why is it important to separate material from mixture?
Contact [7]

Answer:

Explanation:

Mixtures are impure substances with the following properties:

  • Their composition is indefinite i.e they consisit of two or more elements or compounds in any proportion by mass.
  • Their constituents retains their identity i.e physical properties are retained.
  • They can easily be seperated by physical methods into their constituents.

It is important to seperate materials from mixtures because mixtures do not undergo chemical changes when they combine. This implies that they can easily be seperated using simple seperation techniques with the constituents still retaining their properties.

How do you think this food web would be affected if the plants were eliminated
NNADVOKAT [17]
The Answer would be C. Without plants in the ecosystem, it could not feed. Plants are mainly the only producers that feed 3rd level consumers which feed 2nd level consumers which feed 1st level consumers.

Indicate whether the pair of structures shown represent stereoisomers, constitutional isomers, different conformations of the sa
aalyn [17]

The structures shown are examples of Constitutional Isomer.

In Chemistry, an isomer refers to a molecule that is similar to another but has differences. These differences can be:

  • A difference in the constitution: The molecules have the same formula but the connectivities between elements or arrangement is different.
  • Arrangement in space: The molecules have the same formula and connectivity, but they look different to do an arrangement in space of a position.

The molecules shown have the same formula because the elements in each pair are the same. However, the way these elements are connected is slightly different because the Br and the CH3 are connected to different carbons.

Based on this, the difference is the connectivity or constitution, and therefore these are constitutional isomers.

7. predict how atoms such as c, h, o, and n share electrons in a covalent bond, the role of electronegativity, and the potential
Lena [83]

The atoms C,H,O and N becomes more electronegative as the periodic table's right side and top get increasingly electronegative as you move down it. A hydrogen bond needs to share elements with hydrogen in order to exist.

As you move up and to the right of the periodic table, the electronegative properties increase. To form a hydrogen bond, elements would have to be shared with hydrogen. Each element becomes increasingly electronegative as you move further right on the periodic table, with the exception of noble gases (which aren't particularly reactive).

In order to obtain stability, atoms C, H, O, and N would therefore most likely desire to share their electrons (i.e., they are more electronegative because they wish to "hog" electrons). Due to its intermediate electronegativity, hydrogen has a mid-range potential for forming bonds with other molecules.
