Well it depends what kind of gas, but Methane (or natural gas) is called just Mathane gas. Laughing gas is called Nitrous oxide. Some names of gases include hydrogen, helium, oxygen, argon, krypton, neon, nitrogen, fluorine, chlorine, xenon and radon. Gases that are compounds include carbon dioxide, carbon monoxide, methane, nitrous oxide, ozone and hydrogen sulfide. Other types of gases include vapor and steam.

Answer:
undergo death as result of the water loss from cell
Explanation:
The ingredients such as honey, jellies, Jams, preserves and other food which have high sugar content are contaminated hardly by the bacteria because due to the presence of high amount of the sugar and carbohydrates, the solution of the them becomes hypertonic in nature and if a bacteria acts on such solution, the result is the loss of the water from their cell and ultimately the bacteria dies. So, they remain fresh even if their containers are left open at the room temperature.
<span>X is acetic acid or CH3COOH
Acetic acid belongs to the homologous series; alkanoic acids; which are group of weak acids. They react with alkanols or alcohols to form esters or what we call alkyl alkanoates in presence of concentrated sulfuric acid. Additionally, they react with carbonates to yield a salt, water and carbon dioxide gas.
(a) Acetic acid reacts with ethanol to form ester in presence of concentrated sulphuric acid (H2SO4)
CH3COOH + C2H5OH ----------------------> CH3COOC2H5 + H2O
Product formed is Ethyl ethanoate or ethyl acetate.
(b) The reaction will be; Na2CO3 + 2CH3COOH ---------> 2CH3COONa + H2O + CO2
Effervescence will be observed due to the production of Carbon dioxide gas.</span>
