When an acid is added to water, hydronium ions are formed.
What happens when the acid is added to water?
The acid has the ability to give protons that is hydrogen ions. When acid is added to water, water acts as base and takes up the protons released by the acid and forms hydronium ions that is H3O+ ions.
This process is exothermic in nature that is it releases heat. So acid is always added to water and not water to acid.
Therefore, when an acid is added to water, it gives hydronium ions in the water.

The law that relates temperature, pressure, volume, and the number of moles of a gas under perfect conditions is ideal gas law (option C).
<h3>What is ideal gas law?</h3>
Ideal gas law in physics refers to the equation of state of an ideal gas. The law equation is as follows:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- T = temperature
- R = gas law constant
Therefore, it can be said that the law that relates temperature, pressure, volume, and the number of moles of a gas under perfect conditions is ideal gas law.

They are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.
<h3>What is a covalent bond?</h3>
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms.
Sometimes, while naming the chemical compounds, a problem arises when compounds with “ao” and “oo” are written with -ide name. Conventionally, they are converted into a single “o”.
For example, the “ao” in the dichlorine hept-ao-xide (). This “ao” in the can be converted into “o”. As the result, the correct name of this compound would be dichlorine hept-o-xide.
Hence, they are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.

Answer : The rate law for the following mechanism is
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
As we are given the mechanism for the reaction :
Step 1 : (fast)
Step 2 : (slow)
Overall reaction :
The rate law expression for overall reaction should be in terms of A and B.
As we know that the slow step is the rate determining step. So,
The slow step reaction is,
The expression of rate law for this reaction will be,
............(1)
Now applying steady state approximation for , we get:
...........(2)
Now substituting equation 2 in 1, we get:
Hence, the rate law for the following mechanism is
