Equilibrio ácido-base 1. Aplicando la teoria de Brŏnsted-Lowry sobre ácidos y bases, completa y explica el comportamiento de cada ión o molécula y las parejas ácido-base conjugado: a) \( \mathrm{HCl}+\mathrm{H}_{2} \mathrm{O} \) b) \( \mathrm{H}_{2} \mathrm{CO}_{3}+\mathrm{H}_{2} \mathrm{O} \) c) \( \mathrm{NH}_{3}+\mathrm{H}_{2} \mathrm{O} \) d) \( \mathrm{HF}+\mathrm{H}_{2} \mathrm{O} \) e) \( \mathrm{KOH}+\mathrm{H}_{2} \mathrm{O} \)

Give the valency (charge and number) for the following (a) magnesium

Write the formula for the compound formed between calcium and hydroxide:

Nobelium-259 is a radioactive substance that decays according to the following function, where \( y_{0} \) is the initial amount present, and \( y \) is the amount present at time \( t \) (in minutes). \[ y=y_{0} e^{-0.0119 t} \] Find the half-life of Nobelium-259. Do not round any intermediate computations, and round your answer to the nearest tenth.
