Answer:
12 carbon, 22 hydrogen, 11 oxygen
Explanation:
Our equation is: Sugar + 
⇒ 
+ 
This is already balanced which means that the number of atoms for each type of element on each side should be the same.
On the right side, there are 11 * 2 = 22 hydrogen atoms, 11 * 1 + 12 * 2 = 11 + 24 = 35 oxygen atoms, and 12 * 1 = 12 carbon atoms.
Currently on the left, there are 12 * 2 = 24 oxygen atoms. That means that sugar must have 11 oxygen atoms to balance it out. In addition, since the left side currently has no hydrogen or carbon atoms, those must belong to the sugar molecule.
Thus, the sugar molecule has 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.
1) Endothermic reactions:
a) The reaction between ammonium nitrate and water absorbs heat from the surrounding environment.
There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).
b) Ammonium chloride dissolved in a beaker of water makes the beaker cold.
Dissolving this salt absorbs heat from beaker.
c) Water separates on hydrogen and oxygen when an electric current is run through it.
Electrolysis of water is the decomposition reaction (heat is required), because from one molecule (water) two molecules (hydrogen and oxygen) are produced. Water is separated into two molecules.
2) Exothermic reactions:
a) Three drops of concetrated sulfuric acid added to 100 milliliters in a beaker makes the beaker hot.
Energy is released, beaker absorbs that heat.
b) Uranium atoms are split to produce nuclear energy.
Nuclear energy is released.
c) Methane and oxygen are combined to produce methanol and heat.
Balanced chemical reaction: 2CH₄ + O₂ → 2CH₃OH + heat.
Inhibitor
Explanation:
Adding an inhibitor will slow down a chemical reaction. Inhibitors works like a negative catalyst.
The addition of a foreign body can influence the rate of a reaction.
- When a foreign body slows down a reaction, it is called an inhibitor.
- An inhibitor is a negative catalyst that will slow down a reaction.
- Such substances do not allow a reaction to proceed freely and very fast.
- They work in the opposite way a normal catalyst would.
- It is good to know conditions and chemicals that can inhibit a chemical reaction.

Convection
Convection is transfer of heat through fluid (liquid or gas) caused by their molecular motion. In convection, heat current flows in a vertically upward direction. Macaroni rising and falling in a pot of boiling water is due to convection
The answer would be permeable because permeable means let's liquid through easily.
