Answer:
The person’s kinetic energy is 1,025 J
Explanation:
Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and in a position of rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.
Kinetic energy is represented by the following formula:

where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m/s).
In this case:
- v= 5

Replacing:

Solving:
Ec= 1,025 J
<u><em>The person’s kinetic energy is 1,025 J</em></u>
Answer:
0.0222 mol KCl
Explanation:
2 KClO3 (s) 2 KCl (s) + 3 O2 (g)
2.73 g x mol
x g KCl = 2.73 g KClO3 x[ (1 mol KClO3)/ (122.5 g KClO3) ] x [(2 mol KCl)/ (2 mol KClO3)]
x g KCl = 0.0222 mol KCl
<u>Answer:</u> The chemical formula of the compound formed is 
<u>Explanation:</u>
Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.
We are given:
An anion having chemical formula
named as sulfate ion
This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.
Hence, the chemical formula of the compound formed is
