Answer:: A photovoltaic cell converts light into electrical energy. Suppose a certain photovoltaic cell is only 63.5% efficient, in other words, that 63.5% of the light energy is ultimately recovered. If the energy output of this cell is used to heat water, how many 520 nm photons must be absorbed by the photovoltaic cell in order .
Explanation:
With the increase in temperature, the state of matter of water will changed.
<h3>What happen if the temperature of the system is increased?</h3>
If the temperature of water is increased then the state of matter will change from liquid state to gaseous state because the temperature break down the bonds that is present between two water molecules.
So we can conclude that with the increase in temperature, the state of matter of water will changed.

Answer:
H₂O = 3.56 moles
MgCl₂ = 1.78 moles
Explanation:
Given data:
Moles of HCl = 3.56 mol
Moles of water produced = ?
Moles of MgCl₂ produced = ?
Solution:
Chemical equation:
2HCl + Mg(OH)₂ → MgCl₂ + 2H₂O
Now we will compare the moles of HCl with water and magnesium chloride.
HCl : MgCl₂
2 : 1
3.56 : 1/2×3.56 = 1.78 mol
HCl : H₂O
2 : 2
3.56 : 3.56 mol
