Natural polymer is more similar chemically to biopolymers.

Polymers are large molecules or high-molecular weight compounds formed from small repeating units. These repeating units are called monomer. Polymers are synthesized naturally and artificially. The number of repeating units in a chain is called the degree of polymerization.

There are two types of polymers:

1. Natural Polymers

2. Synthetic Polymers

Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules.

Synthetic polymers are the human-made polymers sometimes referred as plastics. The two major types of synthetic polymers are addition polymers and condensation polymers.

What are biopolymers?

Biopolymers polymer materials that form in living organisms. There are three main biopolymers in living systems; polysaccharides, proteins and polynucleotides (nucleic acids). The structural unit of polysaccharides is monosaccharides (sugars). When two monosaccharides join together to form a glycosidic bond, it releases a water molecule. Therefore, polysaccharides are condensation polymers. Polysaccharides play structural and functional roles in organisms. Glycogen is a storage polysaccharide, whereas cellulose is a component in the cell walls of plant cells. Glucose is the monomer for both glycogen and cellulose polymers.

Hence, we have conclude Biopolymers  are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules.

At 506 K and 2.05 atm, if 6.00 grams of H2 will reacts with excess N2 what volume in liters will be produced of NH3? (R = 0.0820
Nady [450]

Answer:

  • 90.4 liter

Explanation:

You must convert the 6.00 grams of H₂ into number of moles, and then use the stoichiometry of the reaction to find the number of moles of NH₃, which can be converted into volume using the ideal gas equation.

<u></u>

<u>1. Number of moles of H</u><u>₂</u>

  • number of moles = mass in grams / molar mass
  • molar mass of H₂ = 2.016g/mol
  • number of moles = 6.00grams / 2.016g/mol = 2.97619mol

<u></u>

<u>2. Number of moles of NH</u><u>₃</u>

<u></u>

i) Chemical equation:

  • 3H₂(g) + N₂(g) →  2NH₃(g)

ii) Mole ratio:

  • 3 mol H₂ : 2 mol NH₃

iii) Proportion:

  • x mol  NH₃ / 2.97619mol H₂ = 3 mol NH₃ / 2 mol H₂

  • x = 4.4642857mol NH₃

<u>3. Volume of NH₃</u>

  • pV = nRT
  • V = nRT/p
  • V = 4.4642857mol × 0.08206 atm·liter/(K·mol) × 506K / 2.05atm
  • V = 90.4 liter

Hydrocyanic acid is a weak acid. Therefore, the salt KCN is
Step2247 [10]
It is basic because of the fact that it has a strong base which is KOH and a weak acid HCN and the strong base causes it to remain more basic.

12 = 3X X = <br> 7X = 57 X = <br> 11X = 27.7 X =
dybincka [34]

Answer:
1. x=4
2.x=\frac{57}{7}
3.x=\frac{27.7}{11}

Explanation:

Given the following questions:

12=3x
7x=57
11x=27.7

In order to find the answers to these questions, we have to recognize that in order to isolate the variable we need to divide on both sides.

Question one:
12=3x
\frac{3x}{3} =\div3
12\div3=4
x=4

Question two:
7x=57
\frac{7x}{7} =\div7
57\div7=8.14285714=\frac{57}{7}
x=\frac{57}{7}

Question three:
11x=27.7
\frac{11x}{11} \div11
27.7\div11=2.51818182=\frac{27.7}{11}
x=\frac{27.7}{11}

Hope this helps.
