Jane made this picture to represent a chemical reaction: Two circles, one white and the other gray are shown on the left. A smal
7nadin3 [17]

It represents a decomposition reaction because one reactant breaks apart and forms two products.

Explanation:

The type of chemical reaction depicted by Jane represents a decomposition reaction because on reactant breaks apart and forms two products.

In this reaction XY breaks apart to form X and Y. This is a decomposition reaction.

                     XY   →   X + Y

  • Decomposition or cracking is the formation of two or more products from a single reactant.
  • The break down of a compound into individual atoms or molecules falls into this category.
  • The extreme instability of a compound drives such a reaction.
  • The products is usually stable or it can dissociate further till it is stable.

Geologist know that potassium 40 decays to argon 40, with a half life of 1.3 billion years. analysis of a hypothetical sample of
meriva

First let us calculate for the rate constant k from the formula:

k = ln(2) / t0.5

where t0.5 is the half life

k = ln(2) / 1.3x10^9 years

k = 5.33x10^-10 years-1

 

Then we use the formula:

A/Ao = e^-kt

where A/Ao is the amount remaining = 25% = 0.25, t is time

 

Rearranging to get t:

t = ln(A/Ao) / -k

t = ln(0.25) / (-5.33x10^-10 years-1)

t = 2.6x10^9 years
