An atom that has gained or lost electrons is called _____.
jek_recluse [69]
It called cation, Well, When an atom gains or loses an electron, it attains a net charge and becomes an ion. When electrons are lost, the resulting ion is called cation and when electrons are gained, the resulting ion is called an anion. So, Cations have a net positive charge, while anions have a net negative charge. it is true.

Which substance, when dissolved in water, forms a solution that conducts an electric current?
Margarita [4]
Missing question: 
<span>(1) C2H5OH (3) C12H22O11
(2) C6H12O6 (4) CH3COOH.

Answer is: 4) CH</span>₃COOH, acetic acid.
In water, acetic acid dissociates on ions, so it can conduct electricity:
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
When we put electrodes (cathode and anode) in acetic acid solution, positive and negative ions migrate to electrodes.<span>
Negative acetate ions go to positive electrode and gives electrons to electrode.
<span>Positive hydrogen ions go to negative electrode and gain electrons.</span></span>

Which of the two types of synthetic polymer is more similar chemically to biopolymers? Explain.
loris [4]

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.
