Answer:
aqueous acid is used as a reagent.
Explanation:
Addition of Grignard reagent in aldehyde and followed by the acidification give rise to the primary or secondary alcohol. when the formaldehyde is used than the primary alcohol is formed otherwise secondary alcohol is formed.
in this reaction we also use the aqueous acid for the acidification as a reagent. We add aqueous acid when ethanol is present. This is because ethanol is get converted in the presence of aqueous acid into the chloroethane.
b) LiH (s) + H₂O (l) --> LiOH (aq) + H₂ (g)
When an alkali metal reacts with water it always produces the metal hydroxide and hydrogen gas which is liberated into the air.
2M(s)+2H₂O (l) →2MOH (aq)+ H₂ (g)
Lithium reacts with water very vigorously.
Alkali metals need to be stored under oil to prevent them from reacting with the oxygen and water vapour in the air. The reactivity of the alkali metals increases down the group.
Alkali metals consist of the following metals:
Lithium, sodium, potassium, rubidium, caesium.
Lithium, sodium and potassium also react vigorously with water and produce hydrogen gas and which is liberated in the air.

Yes, if we're talking about intramolecular bonds
Answer:
100mL of chloromethane
Explanation:
Based on the equation:
Cl₂(g) + CH₄(g) → HCl(g) + CH₃Cl(g)
<em>1 mole of chlorine reacts per mole of methane to produce 1 mole of HCl and 1 mole of chloromethane</em>
<em />
Avogadro's law says that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. Using Avogadro's law we can say of the equation that:
<em>1 mL of chlorine reacts per mL of methane to produce 1 mL of HCl and 1 mL of chloromethane</em>
Because the system stays under constant pressure and temperature.
As 100mL of Cl₂ reacts with excess of CH₄ and 1mL of Cl₂ produce 1mL of CH₃Cl there are produced:
<h3>100mL of chloromethane</h3>
Answer:
The electrons will be added by the hydrogen.
Explanation:
If we fire a single electron towards the hydrogen atom, the hydrogen atoms added the electron to its shell by applying force of attraction and becomes stable as well as non reactive in nature because the hydrogen attains the electronic configuration of helium which is a noble gas and have completed its outermost shell. The proton that is present in the nucleus attracts this electron and compel it to add in the electron.
