According to the law of multiple proportions, if 12 g of carbon combine with 16 g of oxygen to form co, the number of grams of c
scZoUnD [109]

The amount of carbon combined with oxygen in order to form Carbon Dioxide(CO₂)  is 12 grams

The Law of Multiple proportions is one of the basic laws in chemistry along with the Law of Definite proportion. This law was proposed by John Dalton in 1803. The law states that if two elements react to form one or more compounds then the ratio of masses of both the elements is in the ratio of small whole numbers.

It is known that Carbon can form two different compounds while reacting with Oxygen that is: Carbon Monoxide, Carbon Dioxide. For Carbon Monoxide, 12g of Carbon needs to react with 16g of Oxygen. Whereas, In Carbon Dioxide, 12g of Carbon needs to react with 32g of Oxygen. So the mass of Carbon is equal in both cases is 12g.

                      C(12g)   +   O(16g)   ⇒  CO   (Carbon Monoxide)    

                      C(12g)   +  2O(32g) ⇒  CO₂  (Carbon Dioxide)

At equal concentrations would a nonelectrolyte (e.g. glucose) or electrolyte (e.g. nacl) containing solution have a lower freezi
Anestetic [448]
Answer is: solution of electrolyte will have lower freezing point than solution of nonelectrolyte.
This is because salt solution has more particles in of sodium chloride (sodium and chlorine ions) than in same concentration of glucose. Electrolytes better separates into particles in water because of their ionic bond.<span>
