Electrons in sigma <span>bonds remain localized between two atoms. Sigma </span><span>bond results from the formation of </span><span>a molecular orbital </span><span>by the end to </span><span>end overlap of atomic </span>orbitals. Electrons<span> in pi</span> bonds can become delocalized between more than two atoms. Pi bonds result from the formation of molecular orbital by side to side overlap of atomic orbitals.

Answer is: <span>ch3co2h; acetic acid.
</span><span>An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or protons.
</span>Acetic acid dissociate in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻).
<span>Balanced chemical reaction (dissociation):
CH</span>₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
thunderstorms and heavy rain
Explanation:
The weather in a region with an incoming air mass made up of moist air is predominantly that of thunderstorms and heavy rain.
Moist air brings in rainfall and thunderstorms. They are peculiar and predominant in tropical regions of the world .
- A moist air is an air mass that is moisture laden or full of water vapor.
- They are usually formed where evaporation of water vapor from sea water is very high.
- The evaporated water is warmer and lighter than the surrounding air.
- By virtue of this, it moves inland and condenses to form massive rainfall accompanied by thunderstorm.

The answer is ( The concentrations of the products and reactants do not change.)
HNO3 is a strong acid while HBrO is weak acid.
Therefore we ignore the presence of the weak acid such that we consider the pH of the strong acid.
Therefore; since pH= - log (H+)
Hence pH= -log 0.18
= 0.745
Thus the pH of the mixture is 0.745
