Answer:

Mass of calcium chloride produced = 24.14 g

Explanation:

Given data:

Mass of ammonia produced = 7.4 g

Mass of calcium chloride produced = ?

Solution:

Chemical equation:

2NH₄Cl + CaO → 2NH₃ + H₂O + CaCl₂

Number of moles of ammonia produced:

Number of moles = mass/molar mass

Number of moles = 7.4 g/ 17 g/mol

Number of moles = 0.435 mol

Now we will compare the moles of ammonia and calcium chloride.

NH₃ : CaCl₂

2 : 1

0.435 : 1/2×0.435 = 0.2175 mol

Mass of calcium chloride produced:

Mass = number of moles × molar mass

Mass = 0.2175 mol ×110.98 g/mol

Mass = 24.14 g

The decay of the isotope iodine-131 is first-order with a rate constant of 0.138 d−1. All radioactive decay is first order. How

Allisa [31]

Answer:

16.7 days

Explanation:

We are given;

A radioactive isotope Iodine-131`

The decay rate is 0.138 d⁻¹

The percent decayed is 90%

We are suppose to calculate the number of days for the decay.

Using the formula;

$In(\frac{[A_{0}]}{[A]})=kt$

Where, $[A_{0}]$ is the initial concentration and $[A]$ is the new concentration.

Rearranging the formula;

$t=In(\frac{[A_{0}]}{[A]})/k$

Assuming the initial concentration is x, then the final concentration after 90% decay will be 0.10x

Therefore;

$t=In(\frac{[x]}{[0.10x]})(\frac{1}{0.138})$

$t=In(\frac{[1]}{[0.10]})(\frac{1}{0.138})$

$t=In(10.0)(\frac{1}{0.138})$

$t=(2.3026)(\frac{1}{0.138})$

$t=16.685$

Time = 16.7 days

Therefore, it will take 16.7 days for 90% of I-131 to decay to Xe-131
