What is an example of how to supply activation energy to begin reaction
Sergio039 [100]

Heating the reaction flask on a hot plate is an example of supplying activation energy to begin a reaction.

Explanation:

<u>Definition:</u>

Activation energy is defined as the minimum amount of energy required to start a particular chemical reaction.

For example: When hydrogen and oxygen are mixed together it does not immediately start the reaction to form water. So, to start the reaction a small electric spark is provided or it is heated to provide some energy. This energy causes the molecules of hydrogen and water to react, thus producing even more molecules to react and finally water is formed.

Here the electric spark or the heat provided is the activation energy.

Predict the energy trend as a substance changes from a solid to liquid to gas on this graph.
Vladimir [108]
Answer:
            Option-A (<span> It would increase from bottom left to top right) is the correct answer.

Explanation:
                   As we know converting solids into liquids and converting liquids into gases require energy. This energy provided increases the energy of the state and its particles start moving with higher velocities. Therefore, the energy of solids will be lower than liquids and gases respectively. While, liquids have greater energy than solids but less energy than gases. And, gases are the most energetic than solids and liquids.</span>

krok68 [10]

Answer:

Atoms of sulfur = 9.60⋅g32.06⋅g⋅mol−1×6.022×1023⋅mol−1

Explanation:

because the units all cancel out, the answer is clearly a number, ≅2×1023 as required.
