C2H5OH + 302 →2C02 + 3H20, what is the mole ratio
of ethanol to water?

The mole ratio  of ethanol to water : 1 : 3

Given

Reaction

C2H5OH + 302 →2C02 + 3H20

Required

The mole ratio

Solution

In a chemical reaction equation, the mole ratio of the reacting compound (reactants or products) is indicated by the reaction coefficient

The reaction coefficient is determined from the number of elements reacting by holding the principle that the number of elements in the reactants is equal to the number of elements in the product

In the above reaction, the ethanol-C2H5OH coefficient is 1 while the reaction coefficient of water-H20 is 3 so that the mole ratio = 1: 3

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

b.

the accuracy of the data.
