Answer is: <span>to convert solar energy into the chemical energy of sugars.
</span><span>Solar energy is stored in chemical bonds of sugars (glucose for example).
</span><span>In carbon dioxide, carbon has oxidation number +4 and in photosynthesis carbon gain electrons (solar energy), so
his oxidation number is lowered (reduced). Light energy is transformed
into chemical energy, that is stored in carbohydrate molecules
(glucose), which are synthesized from carbon
dioxide and water.</span>
Answer:
20.4 Miles
Explanation:
If Terry's riding speed is reduced by 3mph, he would be riding at 12mph.
12*1.7 = 20.4 miles
(miles per hour literally means how many miles you can travel in an hour at your current speed)
Answers are:
1) The balanced oxidation half reaction: 2I⁻(aq) → I₂(s) + 2e⁻.
Iodine is oxidized (lost electrons) from -1 to neutral charge (0).
2) The balanced reduction half-reaction: 2H₂O(l) + 2e⁻ → H₂(g) + 2OH⁻.
Hydrogen is reduced (gain electrons) from +1 to neutral charge.
3) The oxidation <span>reaction takes place at the anode.</span>
Explanation:
In HCL, one positive atom is given to chlorine from hydrogen so that it can complete it's octate. chlorine take one electron from hydrogen.
In NaCl, Sodium takes one electron from chlorine to complete its orbit with eight electrons. Chlorine gives one electron to sodium.
