Answer: polymers

A polymer are large molecules made up of repeating units, referred to as monomers.

Explanation:

Polymers are macromolecule with large size and high molecular mass. They consists of several repeating units of simpler molecules known as monomers.

Examples of polymers found in plants are

- starch composed of several glucose units linked by glycosidic bonds

- cellulose composed of several repeating glucose units linked by glycosidic bonds as well

An example of polymers found in animals is

- glycogen composed of several units of glucose monomers linked by glycosidic bonds

Answer:

Polymers

Explanation:

Polymers are compounds comprising of Long chain of monomer units produced naturally or artificially .

Polymers are very important in everyday life. Polymers are used in producing automobile parts, healthcare machines, nylons, plastics etc.

Polymers also make up some components of living organisms such as starch , cellulose which are found in plants and are excellent sources of energy.

2 of the important properties of gases. SaveStylesFormat Instructions

lyudmila [28]

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internalcombustion engine provides a good example of the ease with which gases can be compressed.

14. Describe the phase change during: Melting: Boiling: Condensing: Freezing

Sergio [31]

Answer:

Explanation:

Melting: it is a phase change from solid to liquid. It is usually attained when a substance reaches it melting point as heat is supplied to it. The vibrating particles break loose and begins to move like a liquid. Melting of iron is an example.

Boiling; is a phase change from liquid to gases. When substances reaches their boiling points when heat is supplied they begin to boil and form gases. An example is the boiling of water. Boiling usually occurs when the vapor pressure is equal to the atmospheric pressure around.

Condensing: is a phase change from gas to liquid. When gases are cooled they condense back to liquid. Example is rain clouds.

Freezing: is a phase change from liquid to solid.

What is the empirical formula of a compound containing 90 grams carbon, 11 grams hydrogen, and 35 grams nitrogen? (5 points)

algol13

Answer:

1) C₃H₄N

Explanation:

The empirical formula of a compound is the formula that gives the positive integer ratio of the atoms of the elements in the compound in the simplest form

The mass of carbon in the compound = 90 grams

The molar mass of carbon = 12.011 g/mol

The number of moles of carbon = 90 g/(12.011 g/mol) ≈ 7.4931313 moles

The mass of hydrogen in the compound = 11 grams

The molar mass of hydrogen = 1.00794 g/mol

The number of moles of carbon = 11 g/(1.00794 g/mol) ≈ 10.913348 moles

The mass of nitrogen in the compound = 35 grams

The molar mass of nitrogen = 14.0067 g/mol

The number of moles of carbon = 35 g/(14.0067 g/mol) ≈ 2.49880414 moles

Dividing by the smallest mole ratio gives;

The proportion of carbon, C = 7.4931313/2.49880414 = 2.9987 ≈ 3

The proportion of nitrogen, N = 10.913348 /2.49880414 = 4.367 ≈ 4

The proportion of nitrogen, N = 2.49880414 /2.49880414 = 1

Therefore, the empirical formula of the compound is C₃H₄N.
