Elimination cannot take place if the adjacent Carbon atom has no immediately bonded Hydrogen atom. An isomer of this will by:
(CH₃)₃C-CH₂Br
<span>Endothermic reactions take in heat from the environment in order to react while exothermic reactions release heat during the reaction. For this, D must be true as the products have less energy because they have released heat during the reaction. A and C are incorrect because they products and reactants are equal and B is wrong because the energy of the products would be more as the reaction took in heat.</span>
Explanation:
Weak bases, just like weak acids, dissociate slowly when dissolved with water. An Arrhenius acid is any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion. An Arrhenius base is any substance that gives the OH-, or hydroxide, ion when it dissolves in water

T½=18.72days
therefore t¾=18.72+½ of 18.72
we have 18.72+9.36=28.08days
