What happens when an electron absorbs energy?

1 answer:

Answer:

A

Explanation:

this is because the electrons are attracted to the protons, the stronger the attraction and energy level the closer the electrons are to the nucleus. this moves them to a higher energy orbital. For example in a Bohr diagram.

Concerning Boyle's Law, if you had a gas at a pressure of 101 kPa and decreased the volume of the container holding the gas to o

Viefleur [7K]

Answer:

$P_2=404 kPa$

Explanation:

Hello,

In this case, the Boyle's is mathematically defined via:

$P_1V_1=P_2V_2$

Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:

$V_2=\frac{1}{4} V_1$

We can compute the new pressure:

$P_2=\frac{P_1V_1}{V_2} =\frac{P_1V_1}{\frac{1}{4} V_1} =\frac{101kPa*V_1}{\frac{1}{4} V_1} \\\\P_2=4*101kPa\\\\\\P_2=404 kPa$

Which means the pressure is increased by a factor of four.

Regards.

The energy acquired in the light-dependent reactions is used in the light-independent reactions to build glucose molecules. How

jeyben [28]

Answer: through energy carriers, ATP and NADPH

Explanation:in the light dependent stage,energy from a light photon is used to create ATP through ADP and an inorganic phosphate.

It does this by the transfer of energetic electron from one electron carrier to another.NADPH is also formed.

In the light independent reaction,ATP and NADP are used to reduce carbon dioxide to 3-phosphoglycerate
