Daylight increases and decreases base upon how the earth spins on its axis right. So basically during a certain time of year (summer) the sun is shining based upon how the earth spins on its axis giving more daylight.
Answer:
12 moles of water (H₂O)
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
6CO₂ + 6H₂O —> C₆H₁₂O₆ + 6O₂
From the balanced equation above,
6 moles of H₂O reacted to produce 1 mole of C₆H₁₂O₆.
Finally, we shall determine the number of mole of H₂O required to produce 2 moles of C₆H₁₂O₆. This can be obtained as follow:
From the balanced equation above,
6 moles of H₂O reacted to produce 1 mole of C₆H₁₂O₆.
Therefore, Xmol of H₂O will react to produce 2 moles of C₆H₁₂O₆ i.e
Xmol of H₂O = 6 × 2
Xmol of H₂O = 12 moles.
Thus, 12 moles of water (H₂O) is needed to produce 2 moles of glucose (C₆H₁₂O₆).
The two control bases would be water and salt.
Photon
energy is the energy carried by a single photon with a certain wavelength and
frequency. These terms are related by an equation. <span>
E = hv
where h is the Planck's constant (6.626 x
10-34 J s), v is the frequency.</span>
We calculate the energy as follows:
E = hv
E = 6.626 x 10-34 J s ( 7.31 × 10^14 / s ) = 4.84 x 10^-19 J
