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.

Calculate the number of calories in 1/4 lbs of margarine
Aleonysh [2.5K]

There are 700 Cal in ¼ lb margarine.

Dietitians say there are anywhere from 150 Cal to 200 Cal in an ounce of margarine.  

Let’s split the difference and assume 175 Cal/oz.

<em>a. Given</em>: pounds of margarine

<em>b. Want</em>: number of calories

<em>c. Equalities</em>: 175 Cal = 1 oz; 16 oz = 1 lb

<em>d. Conversion factors</em>: 175 Cal/1 oz or 1 oz/175 Cal; 16 oz = 1 lb or 1 lb/16 oz

We choose the conversion factor that has the <em>desired units on top</em>.

<em>Calculation: </em>

No. of ounces = 0.25 lb × (16 oz/1 lb) = 4 oz

No. of Calories = 4 oz × (175 Cal/1 oz) = 700 Cal
