MatroZZZ [7]

Explanation:

The volume of the copper block is:

32 \times 21 \times 21 = 14112 \: {cm}^{3}

The density of copper is 8.96 g/cm³

So the mass of the copper block is

14112 \times 8.96 = 126443.52 \: g

or 126.44352 kg.

a)

OCH₃⁻ + H₂O →  CH₃OH <em>(methanol) </em>+ OH⁻ <em>(hydroxide)</em>

here, the methoxide ion acted as a base, by bonding with the hydrogen atom released by water to form methanol and hydronium ion

b)

ClO⁻ + H₂O → HClO + OH⁻ <em>(hydroxide)</em>

The Hypochlorite ion bonded with the proton released by water, to form Hypochlorous acid and hydronium ion
