Your attempted answer is correct.
Indeed, certain liquids, including water, could superheat when heated in a perfectly smooth container. The superheating could be interrupted by the minutest speck of dust or impurities causing a mass conversion into steam, observed physically as a bumping, causing splashes and endangering operators. Boiling chips introduce these interruptions constantly and ensure a smooth boiling of the liquid.
Answer:
463.0 g.
Explanation:
- We can use the following relation:
<em>n = mass/molar mass.</em>
where, n is the mass of copper(ii) fluoride (m = 4.56 mol),
mass of copper(ii) fluoride = ??? g.
molar mass of copper(ii) fluoride = 101.543 g/mol.
∴ mass of copper(ii) fluoride = (n)(molar mass) = (4.56 mol)(101.543 g/mol) = 463.0 g.

Explanation:
Tritium follows a first-order decay which can be represented by the following expression.
where,
[H]t is the concentration of tritium at a certain time t
[H]₀ is the initial concentration of tritium
k is the rate constant
If we know the half-life (t1/2), we can calculate the rate constant.
