Concave mirrors, magnifying lens... sorry not sure about the rest
Answer : The correct option is, 
Explanation :
- Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.
Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.
- Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.
Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.
According to the electrochemical series,
most likely to be reduced because
Hence, the ion most likely to be reduced is
.
Answer:
the answer is 119.0023 grams
The 2,4 and 5 positions are accessible for nitration of 1,3‑dimethylbenzene. The final product is shown in the image attached.
<h3>What is nitration?</h3>
Nitration is a type of reaction in which the nitro group (-NO2) is introduced to an aromatic ring. We have to note that in the compound 1,3‑dimethylbenzene, the 2,4 and 5 positions are accessible for nitration as shown.
Hence, the nitration of 1,3‑dimethylbenzene occurs as shown in the image attached with the compound shown being the major product.

There is no energy available to transfer to the surroundings when bonds break as it's an endothermic reaction.
<h3>What is Endothermic reaction?</h3>
This is the type of reaction in which heat is absorbed from the surrounding and is involved in the breaking of bonds.
There is no energy available to transfer to the surroundings when bonds break because it's needed in the conversion of the reactant to product in a chemical reaction.
