I would say that gas is a solution and milk, coke and paint are heterogeneous. If you churn milk butter will emerge and the milk will be left. Paint is made of different types of particles in the mixture. Coke is a solution of sugar water, plus CO2, where the gas emerges from the solution.
Gasoline is the same throughout.
The mass of mercury (Hg) in the products formed as a result of the decomposition of 100g of mercury oxide is 93g (option A).
<h3>What is the law of conservation of matter?</h3>
The law of conservation of matter states that the mass of an element can neither be created nor destroyed.
The law further states that in a chemical reaction, the mass of the reactants must equal the mass of products.
According to this question, 100g of mercury oxide decomposes to produce oxygen of oxygen (O) and mercury (Hg) in a chemical reaction.
If 7g of oxygen (O) is produced in the reaction, the mass of mercury as the other product will be 100g - 7g = 93g.
Therefore, the mass of mercury (Hg) in the products formed as a result of the decomposition of 100g of mercury oxide is 93g.

When we increase the surface area of an object, more atoms are exposed. Since more atoms are exposed, the atoms can react faster, and this is why the rate of a reaction increases when the surface area increases.
For example, lets say we want to heat a potato. If we just put the whole potato in the microwave, it will take a long time for the potato to get thoroughly heated. However, if we chop the potato into smaller pieces, we will observe that it gets heated much faster. This is because we increased the surface area of the potato, which resulted in more potato atoms to be exposed to the heat, and caused the reaction to be faster.
