Amino acid <span> is not an example of a polymer.its an monomer whereas
polymer is made up of repeating subunit and is a large molecule and chemical bond exist
so i think option C is correct for the first
2-
</span>A carbon atom is able to form four single covalent bonds because <span> it has four valence electrons in its outermost energy level or outermost shell so to complete its octate it forms four singl covalent bond
</span>3-<span>An organic compound that contains a carbonyl group with a hydroxyl group attached to it is an example of carboxylic acid
4-</span><span> All of the following release carbon into the atmosphere except the
</span><span>sedimentation of dead organisms.so in my opinion its the correct one
</span>5-Alcohols <span> has a hydroxyl group -O-H attached to a carbon atom
so i conclude option A is correct for last one

hope it helps</span>

The chemical equation is unbalanced and synthesized.

<h3></h3><h3>What is a chemical equation?</h3>

A chemical equation is described as the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.

In a chemical equation, the reactant entities are given on the left-hand side and the product entities is shown on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that indicates towards the products to show the direction of the reaction.

We can conclude that in the chemical equation shown is unbalanced because both amounts of the individual elements and compounds do not reflect on the reactant and product side.

The complete question is below:

After learning about the law of conservation of mass, Sammy became interested in balancing equations. He knew that the symbol for aluminum was Al and silver tarnish was Ag2S. He also knew that mixing the two chemicals yielded pure silver, or Ag, in an aluminum sulfide solution. Here is the equation showing this reaction:

3 Ag2S + 2 Al → 6 Ag + Al2S3

This equation is (synthesis / unbalanced / replacement / balanced), and it represents a(n) (unbalanced / balanced / synthesized / replaced) chemical reaction.

answer choices:

synthesis; balanced

balanced; replacement

unbalanced; synthesized

balanced; balanced

1. Addition of which of the following will increase the solubility of CaCO3 in water? Consider the equilibrium process:

kolbaska11 [484]

Answer: HCl

Explanation:

calcium carbonate dissolves in HCl acid producing CO 2 gas. It will not dissolve in pure water. The Ksp for calcium carbonate in water is 3.4 x 10-9 moldm-3 which is very low. What takes place here is actually a chemical reaction:

CaCO 3 (s) + 2HCl(aq) → CaCl 2 (aq) + H 2CO 3(aq)

This reaction accounts for the solubility of the Calcium carbonate in HCl and not in pure water.
