Corresponding in size or amount to something else.
Answer:
The rest of the wood was converted to gases
Explanation:
According to the law of conservation of mass, the mass on the reactant side must be equal to the mass on the product side. When wood is burned it forms ashes and gases. The mass of the ash plus gases must be equal to the mass of the wood and air used in burning it.
If 3g of wood were burned and the ashes produced weighs 1.2g, it means that the rest 1.8g have been converted to gases
There are 4 energy sublevels are present in the principal energy level n = 4.
<h3>What is sublevels?</h3>
Sub-level is a type of level that is lower than another level or it is a part or component of a big level. S, p, d and f are the four energy levels in which electrons are present.
So we can conclude that 4 energy sublevels are present in the principal energy level n = 4.

This is an example of displacement reaction
<u>Explanation:</u>
- The chemical reaction in which the one element replaces the other element in a compound is called a displacement reaction. This reaction is also called a replacement reaction.
AB + C -----> AC +B
2ZnS + 3O2 -----> 2ZnO + 2SO2
- This happens when A is more reactive than B and gives a stable product. Here the zinc sulfide compound reacts with the oxygen element to the stable product of zinc oxide and sulfur dioxide.
- In short, the more reactive element displaces the less reactive element is called a displacement reaction.
