Answer:
if you mix any halogen with any alkali then ionic salt will be formed and also this will cause an exothermic reaction in which heat is getting released
Explanation: it is formed by large number of glucose<span> molecules joined to each other , then when cell need it is digested to produce </span>glucose<span> to be consumed by the cell to produce energy.</span>
Half-life is a time in which the concentration of the substance gets reduced to 50% of the initial concentration. The number of tritium that will be left after 51 years is 0.624 kg.
<h3>What is an isotope?</h3>
Isotopes are chemical substances that have the same atomic number but different atomic mass because they have a different number of neutrons in the nuclei.
The half-life of the isotope, tritium is 12.3 years. Assuming we have 11 kg of substance and a number of years 51 years.
Therefore, the number of tritium that will be left after 51 years is 0.624 kg.

Answer:
a.Phenols have the ability to spread out the negative charge that forms.
Explanation:
This happens because of the aromatic ring the phenols have. When loosing the proton, the anion formed have different resonance isomers due to the double bonds in the aromatic ring. This resonance makes the anion more stable and prevents the reaction going backwards.
On the other hand, regular alcohol doesn't have resonace and the reaction of loosing the proton goes leftward and righward: is in equilibrium.
That equilibrium decreases the acidity of the alcohol.
