Certain mass of carbon burns with a given mass of oxygen to form cert...
The correct answer is option 'B', the Law of constant proportion.
The Law of constant proportion, also known as the Law of definite proportions, states that a given compound always contains the same elements in the same proportion by mass. This means that no matter how the compound is formed, the ratio of the masses of the elements in the compound will always be the same.
When carbon burns with oxygen to form carbon dioxide, the Law of constant proportion is followed because the mass ratio of carbon to oxygen to carbon dioxide remains constant.
Let's break down the process and see how the Law of constant proportion applies:
1. Carbon burns with oxygen:
In this step, carbon reacts with oxygen to form carbon dioxide. The balanced chemical equation for this reaction is:
C + O2 → CO2
2. Mass of carbon:
Let's assume that a certain mass of carbon is burned. The mass of carbon is constant and does not change during the reaction.
3. Mass of oxygen:
To completely react with the given mass of carbon, a specific mass of oxygen is required. The ratio of the mass of oxygen to carbon is fixed and determined by the stoichiometry of the balanced equation.
4. Formation of carbon dioxide:
The carbon and oxygen react to form carbon dioxide. The mass of carbon dioxide formed is determined by the Law of constant proportion. The ratio of the masses of carbon and oxygen in the carbon dioxide is always constant, regardless of the mass of carbon burned.
In conclusion, the Law of constant proportion is used in the formation of carbon dioxide from the burning of carbon with oxygen because the masses of carbon and oxygen combine in a fixed ratio to form carbon dioxide, as stated by the Law of constant proportion.

Certain mass of carbon burns with a given mass of oxygen to form cert...
First, let us write the reaction taking place here
C + O2 → CO2
As per the given condition, when 3.0 g of carbon is burnt in 8.00 g oxygen, 11.00 g of carbon dioxide is produced.
3g + 8g →11 g ( from the above reaction)
The total mass of reactants = mass of carbon + mass of oxygen
=3g+8g
=11g
The total mass of reactants = Total mass of products
Therefore, the law of conservation of mass is proved.
Then, it also depicts that the carbon dioxide contains carbon and oxygen in a fixed ratio by mass, which is 3:8.
Thus it further proves the law of constant proportions.
3 g of carbon must also combine with 8 g of oxygen only.
This means that (50−8)=42g of oxygen will remain unreacted.
The remaining 42 g of oxygen will be left un-reactive. In this case also, only 11 g of carbon dioxide will be formed
The above answer is governed by the law of constant proportions.
