Energy is either released or absorbed. When an electron jumps from high energy to lower, a photon is emitted or released. when the electron goes from low to high, energy is absorbed.

Answer:

Photon

Explanation:

In any material there are various energy level in which electrons are filled. Suppose there are two energy level in a material. Lower energy level has 1eV energy it means atoms which have 1eV can stay in this energy level.Other energy level has 3eV energy it means atoms which have 3eV energy can stay in this state. If atom from 3eV energy level jumps into 1eV energy level that time atom has to emit its excess energy (3eV-1eV=2eV) in the form of photon because in 1eV energy level atoms which have 2eV energy can stay.

Calculate the mass percent of HOCH 2CH 2OH in a solution made by dissolving 3.2 g of HOCH 2CH 2OH in 43.5g of water.

grin007 [14]

Answer:

$\%m/m=6.85\%$

Explanation:

Hello,

In this case, we are asked to compute the by mass percent for the given 3.2 g of ethylene glycol in 43.5 g of water. In such a way, since the by mass percent is computed as follows:

$\%m/m=\frac{m_{solute}}{m_{solute}+m_{solvent}} *100\%$

Whereas the solute is the ethylene glycol and the solvent the water, therefore we obtain:

$\%m/m=\frac{3.2g}{3.2g+43.5g} *100\%\\\\\%m/m=6.85\%$

Best regards.

Which one is a true statement about endothermic reactions? A. I need you from an outside source is continuously being added. B.

tekilochka [14]

Correct answer: "A. Energy from an outside source is continuously being added."
An endothermic reaction is a reaction that is characterised by the system absorbing energy from its surroundings. That energy is usually in heat form. For example, when mixing water<span> with potassium chloride, this reaction will absorb heat and the container will feel cold - endothermic reaction.</span>
