Potential Chemical energy
Explanation:
Potential Chemical energy is stored in a fossil fuel and released in the form of kinetic heat energy when it is burnt.
Potential energy is the energy at rest in a body. It is that energy when no change is happening to a body. There are different forms of potential energy. A good example in fossil fuels is chemical energy.
Kinetic energy of a body is the energy due to the motion of a body. It occurs when particles of a medium are agitated. An example of kinetic energy in fossil fuel occurs when it is burnt.
- the formative process of a fossil fuel stores chemical energy.
- the process prevents energy rich carbon atoms from being converted back into nature by decomposers.
- the hydrocarbon chain stores chemical energy
- the energy is released when the molecules are burnt and they form heat energy, a form of thermal energy.

The color violet has the most light energy because it has higher frequency, and it has the most waves, also known as traveling energy.
Answer: The volume of 9.7 tons of given ethylene glycol is 0.0079 .
Explanation:
Given: Density = 1.11
Mass = 9.7 tons
Convert tons into lb as follows.
Now, lb is converted into kg as follows.
1 kg = 1000 g
So, 8.79 kg = 8790 g
Density is the mass of a substance divided by its volume. Hence, volume of ethylene glycol is calculated as follows.
Thus, we can conclude that the volume of 9.7 tons of given ethylene glycol is 0.0079 .
Density allows you to find that for the coin to look like gold, the correct answer is: the mass must INCREASE
Density is the relationship between the mass of a body and its volume is constant for solids and liquids.
ρ = m / V
where ρ is the density, m the mass and V the volume of the body
The mass of the coin is
m = ρ V
initially the coin is silver (Ag) with density, ρ_{Ag} = 10.94 g/cm³ and the density of gold (Au) is ρ_{Au} = 19.32 gr/cm³
As the density of gold is greater than the density of silver, we must use some chemical method, for example electroplating, to introduce a small layer of gold or other golden material on the surface, as this layer is very thin, the increase in volume is very small, the mass of the coins is
m₁ = ρ_{Ag] V
m₂ = ρ_{Au} V
where m₁ and m₂ are the masses of the silver and gold coins, respectively
What
ρ_{Au} > ρ_{Ag}
the mass of the coin must increase
With the density we can find that for the peel to look like gold the mass must INCREASE

Answer:
7 mL
Explanation:
To prepare a solution by dilution of another one, we can use the equation:
C1V1 = C2V2
where <em>C</em> is the concentration, <em>V</em> is the volume, <em>1</em> is the initial solution, and <em>2</em> the final solution. V represents the total volume. K₂CrO₄ dissolver by:
K₂CrO₄ → 2K⁺ + CrO₄⁻²
So, 1 mol of K₂CrO₄ results in 1 mol of CrO₄⁻², the in a solution of 8.75x10⁻⁴M of CrO₄⁻², it will be 8.75x10⁻⁴M of K₂CrO₄, so the volume of the stock solution will be:
1.25x10⁻³xV1 = 8.75x10⁻⁴x10
V1 = (8.75x10⁻³)/(1.25x10⁻³)
V1 = 7 mL
