Answer:
O.
Explanation:
- The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
- The element which is reduced is the element that gain electrons and its oxidation state be more negative.
<em> O goes from 0 to -2, so, it is the element that is reduced.</em>
Answer:
C
Explanation:
I'm assuming that you meant to type neutral charge.
Since electrons are negative and protons are positive, having a balanced number of both of these would cause an atom to have a neutral charge.
Therefore Chlorine is losing electrons and being oxidized. Hope it helps.
Answer:
A. When temperature increases, the number and energy of collisions between particles increases, which increases the rate of the reaction.
Explanation:
The reaction rate measures the speed with which a reaction proceeds. Based on the collision theory of reaction rates, the rate of a given reaction depends on the number of collisions per time and how successful or effective the collisions are.
Reaction rate in view of the collision theory is very related to concentration and temperature. Both properties are directly proportional to the rate of a reaction.
As temperature increase, the rate of the reaction increases due to the number of effective collisions and the energy of between colliding particles.
Answer:
E) This is not an Oxidation/ Reduction type of reaction
Explanation:
Oxidation involves the loss of electrons while reduction involves the addition of electrons. None of the elements change their oxidation number in the reaction, so this is not an oxidation/reduction type of reaction.
