Answer:

1st: Light excites an electrom from photosystem II

2nd: Light excites an electrom from photosystem I

3rd: Electrons pass through an electron chain, which generates a H+ gradient used to make ATP

4th: Electron reduce NADP+ to NADPH

Explanation:

While the light simultaneously excites both photosystems, it must first occur in photosystem II and then be able to transfer the e-energized to photosystem I

1st Step:

Within the photosystems we find different photosynthetic pigments, that is, capable of absorbing light. These pigments are classified according to the maximum absorption wavelengths.

When the light hits the photosystems they absorb it and the delocalized -e (electrons) are energized or "excited".

Then these energized ones are transferred to molecules within the membrane that houses the pigments.

The e- that takes the photosystem I are provided by the photosystem II

2nd and 3rd Step:

The -e energized from photosystem II are transferred to a transport chain of -e within the membrane containing the pigments. As these -e circulate, they lose energy that is used to translocate H + (protons).

The accumulation of H + within the membrane generates an electrochemical gradient.

H + return to the stroma through the enzyme ATP synthase. This operation is called chemosmosis.

This enzyme uses H + to catalyze the synthesis of ATP (ADP + Pi), a process called phosphorylation.

4th Step:  

The e-energized of photosystem I are used to reduce NADP + and generate NADPH that are used in conjunction with ATP to generate "light independent reactions"

Those lost from photosystem I are replaced by e-de-energized from photosystem II, while those lost from photosystem II are replaced by e-released from water by photolysis.

Water is divided by the energy of light into H + (used in chemosmosis) and oxygen (released as a byproduct)

Core reactions that occur:

¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H

Can be written :

¹⁴₇N (α, H) ¹⁷₈O  , α = ⁴₂He

Fusion and fission reactions are reactions involving atomic nucleus reactions

Fission reaction is a nucleation division reaction by firing a particle usually neutron so that it gets smaller particles of atomic nuclei.

A fusion reaction is a combining reaction of 2 atomic nuclei. Usually what is often used is a reaction between the hydrogen isotope that will form Helium

At the core, the reaction applies the law of eternity

  • 1. energy

the energy before and after the reaction is the same

  • 2. atomic number

the number of atomic numbers before and after the same

  • 3. mass number

the number of mass numbers before and after the same

Particles that play a role in core reactions include

  • alpha α particles ₂He⁴
  • beta β ₋₁e⁰ particles
  • gamma particles γ
  • positron particles ₁e⁰

In general, the core reaction equation can be written:

<h3> X + a ---> Y + b + Q </h3>

X = target core

a = particle fired

Y = new core

b = the particle produced

Q = heat energy

or can be written simply

<h3> X (a, b) Y </h3>

In the ¹⁴₇N atomic nucleus, a fusion reaction occurs with ⁴₂He which produces isotopes of Oxygen and ¹₁H protons.

¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H

This reaction can be written down

¹⁴₇N (α, H) ¹⁷₈O

UkoKoshka [18]

Answer:

m_{Ga}=0.550gGa

Explanation:

Hello!

In this case, since the applied current for the 50.0 mins provides the following charge to the system:

q=0.760\frac{C}{s}*50.0min*\frac{60s}{1min}=2,280C

As 1 mole of electrons carries a charge of 1 faraday, or 96,485 coulombs, we can compute the moles of electrons involved during the reduction:

n_{e^-}=2,280C*\frac{1mole^-}{96,485C}=0.0236mole^-

Then the reduction of Ga³⁺ to Ga involves the transference of three electrons, we are able to compute the moles and therefore the mass of deposited gallium:

m_{Ga}=0.0236mole^-*\frac{1molGa}{3mole^-}*\frac{69.72gGa}{1molGa}  \\\\m_{Ga}=0.550gGa

Best regards!

Which set of properties does a substance such as CO2(g) have?
mylen [45]
Since CO2 (Carbon Dioxide) is a gas these properties would be: -no definite shape and volume. A gas is invisible and colorless to the human naked eye. An example of pure gas would be like air. Just like air, you see no definite shape and weight or volume.
