Reduction <span>always results in a lowering of the oxidation number. The reaction of the system above is written as:
</span><span>Cu2+(aq) + Fe(s) --> Cu(s) + Fe2+(aq)
</span>
From the reaction, we see that copper goes from the +2 to a neutral charge. Lowering of the oxidation number happens so this is the element that is being reduced.
Answer:
The si unit used to measure weight is kilogram /kg
Anything less that 7, would be a base.
Hey there!
CH₄ + 2O₂ → CO₂ + 2H₂O
carbon dioxide: product
methane: reactant
oxygen: reactant
water: product
Methane and oxygen are reactants because they are the substances we start with. They are on the side of the equation that the arrow is pointing away from.
Carbon dioxide and water are products because they are the new substances that are the yields of the equation. They are on the side of the equation that the arrow is pointing towards.
Hope this helps!
