Answer:

Decomposition Reaction

Explanation:

You can determine the type of reaction by writing out a balanced equation.

Solid Potassium Chlorate: KClO3

Potassium Chloride: KCl

Oxygen Gas: O2

Balanced Equation: 2KClO3 -> 2KCl + 3O2

By definition, a decomposition reaction is when a single substance decomposes into two more simpler substances. AB -> A + B

Because the solid potassium chlorate is breaking into two substances, potassium chloride and oxygen gas, it is a decomposition reaction.

What are 3 sentences about the history of Egypt? Thank you for taking aside time to answer this. Please answer this as quickly a
Nataly_w [17]
1) The history of egypt is still unclear; artifacts, how the pyramids were built, gods and whatnot.
2) Egypt's history being uncovered in regards to curses and amulets is still being practiced in the country and some others because of the great influence it had.
3) Egyptians being able to construct such grand structures that still stand (pyramids) serves as evidence that proves Egypt was a very advanced civilization at the peak of their advancement.

If, in a peptide chain, there were 85 amino acids each joined by peptide bonds, how many n-terminus groups would be present?
Crank
If, in a peptide chain, there were 85 amino acids each joined by peptide bonds, there would only be 1 N-terminus group that would be present. The N-terminus group is always the start of the chain of a amino acid chain or a protein or a polypeptide. It refers to the free amine group present that is located at the end part of the chain. So, that no matter how many amino acids in a chain there would always be only one N-terminus group.

5.04 Discussion: Reaction-Rate Factors
saul85 [17]

Increasing the surface area of the reactant by pelletizing the calcium carbonate, and increasing the concentration of hydrochloric acid resulted in increase in the rate of reaction.

<h3>What is reaction rate?</h3>

Reaction rate refers to the rate at which reactant molecules are consumed or the rate at which product molecules are formed.

The factors that affect reaction rate include:

  • Temperature
  • Concentration
  • Surface area of reactants
  • Nature of reactants
  • Presence of catalysts

Given an experiment to determine effect of surface area of reactants  and concentration on reaction rate of dilute hydrochloric acid and calcium carbonate:

It was observed that increasing the surface area of the reactant by pelletizing the calcium carbonate and increasing the concentration of hydrochloric acid made the reaction proceed faster.

In conclusion, reaction rate increases with increase in surface area.
