Answer:
1. Exothermic reaction
2. Is being released
3. The energy comes from the change in energy between reactants and products
Explanation:
The reaction is producing energy. A reaction that produce energy is called a <em>Exothermic reaction.</em>
<em />
As the energy is produced, the energy is being <em>released.</em>
<em />
As you can see in the image, the energy of the reactants is higher than the energy of the products. This change of energy in the chemicals produce the production of energy as heat.
Answer:
KMnO4,H3O^+,75°C
Explanation:
The conversion of cyclohexene to trans-1,2-cylohexanediol is an oxidation reaction. Alkenes are oxidized in the presence of potassium permanganate and acids to yield the corresponding diols.
These diols may also be called glycols. They are molecules that contain two -OH(hydroxyl) groups per molecule. The reaction closely resembles the addition of the two -OH groups of hydrogen peroxide to an alkene.
The bright color of potassium permanganate disappears in this reaction so it can be used as a test for alkenes.
We are given with
V = 12L
T = 298 K
P = 1000 kPa
We are asked to get the number of moles, n
We can solve this using the ideal gas law
PV = nRT
n = PV / RT
Simply substitute the values and use the appropriate value for R.
I'm pretty sure the answer would be that the metal is conductive, which travels through the copper wires.

neutrons are found in the nucleus of an atom.
