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.

carbon disulfide is formed by the reaction of coke (carbon) with sulfur dioxide. how many moles of cs2 will be generated if 8.0
Murrr4er [49]
5C₂ + 4SO₂ ------>  2CS₂  +  8CO

mole ratio of C₂  :  CS₂
                 =   5   :    2

∴ since C₂ contains 8 moles 

  then CS₂ contain   ( \frac{8}{5} )  *  2  moles
                            
                             =  3.2 moles

How many grams of ethylene glycol (c2h6o2 must be added to 1.25 kg of water to produce a solution that freezes at -5.88 ∘c?
e-lub [12.9K]
The freezing point depression is calculated through the equation,
                                    ΔT = (kf)  x m 
where ΔT is the difference in temperature, kf is the freezing point depression constant (1.86°C/m), and m is the molality. Substituting the known values,
                                   5.88 = (1.86)(m)
m is equal to 3.16m

Recall that molality is calculated through the equation,
                                  molality = number of mols / kg of solvent
                                       number of mols = (3.16)(1.25) = 3.95 moles
Then, we multiply the calculated amount in moles with the molar mass of ethylene glycol and the answer would be 244.9 g.
