Electromagnetic Waves

Explanation:

Electromagnetic waves do not require a medium to propagate whereas mechanical wave does.

Example: Sound wave is mechanical wave. It needs a medium to transfer energy from one place to another.

And, X-rays. These are electromagnetic waves & these transfer energy via electric & magnetic fields.

The process of generating electricity from dams and nuclear power plants is very different, but some of the energy transformatio
Alexxx [7]

Answer:

Kinetic energy to mechanical energy, and mechanical energy to electrical energy.

Explanation:

From the Law of conservation of Energy, which state that energy can neither be created nor destroyed but can be transformed from one form to another. Energy transformation is essential in science and technology, in the process of generating electricity from dams and nuclear power plants

some of the energy transformations are the same, the energy transformations occur in both dams and nuclear power plants is Kinetic energy to mechanical energy, and mechanical energy to electrical energy. Kinectic energy is the energy in motion which means the dams is a running water and posses a Kinectic energy then it's is been convert to mechanical energy (which is the macroscopic energy) then to electrical energy by producing light.

If the reactants have a potential energy of 10.2 kJ/mol and the products have a potential
Citrus2011 [14]

Answer:

The ΔH is 5.5 kJ/mol and the reaction is endothermic.

Explanation:

To calculate the ∆H (heat of reaction) of the combustion reaction, that is, the heat that accompanies the entire reaction, you must make the total sum of all the heats of the products and of the reagents affected by their stoichiometric coefficient ( number of molecules of each compound participating in the reaction) and finally subtract them:

Combustion enthalpy = ΔH = ∑H products - ∑Hreactants

In this case:

ΔH = 15.7 kJ/mol - 10.2 kJ/mol= 5.5 kJ/mol

An endothermic reaction is one whose enthalpy value is positive, that is, the system absorbs heat from the environment (ΔH> 0).

<u><em>The ΔH is 5.5 kJ/mol and the reaction is endothermic.</em></u>
