An oxidation-reduction reaction that is also a synthesis reaction
Aleonysh [2.5K]

The example of a chemical combination that can also be said to be a synthesis reaction is; 2Mg(s) +O_{2} (g) -- > 2 MgO(s)

<h3>What is a synthesis reaction?</h3>

We know that the meaning of the synthesis reaction is quite central as we attempt to answer the question that is lying right before us here. If we are talking about the synthesis reaction then our mind must have to go to the kind of reaction in which there is the combination of two or more so as to produce a single compound.

As we are talking about the synthesis reaction, we would have to look at the reaction that would give rise to a single product as it has been written. Let us also recall that we have been told that the reaction is a  oxidation-reduction reaction thus there is a change in oxidation number in the process of the reaction as shown.

Name the five methods used for the formation of salts??
Viefleur [7K]

Explanation:

In chemistry, a salt is a chemical compound consisting of an ionic assembly of cations and anions.[1] Salts are composed of related numbers of cations (positively charged ions) and anions (negatively charged ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic, such as chloride (Cl−), or organic, such as acetate (CH

3CO−

2); and can be monatomic, such as fluoride (F−) or polyatomic, such as sulfate (SO2−

4).
