Answer:

<em><u>The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.</u></em>

<u>Explanation:</u>

<u></u>A g^{+} \text {and } A l^{3+} - Separated by 6M HCl

Silver and aluminum ions can be separated using the acid, 6M HCl.

C u^{2+} \text { and } C a^{2+}- Separated by H₂S

Copper and Calcium ions can be separated by the reagent hydrogen sulfide, H₂S.

M g^{2+} \text { and } K^{+} - Separated by (NH₄)₂HPO₄ in NH₃

Magnesium and Potassium ions can be separated by the reagent Ammonium hydrogen phosphate in ammonia.

Calculate the mass of one atom of zinc in grams. (Hint: g/particle)
USPshnik [31]

Answer: 10.17\times 10^{-23}g

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given atoms}}{\text{Avogadro's number}}=\frac{1}{6.023\times 10^{23}}=0.16\times 10^{-23}atoms

1 mole of zinc weighs = 65.38 g

0.16\times 10^{-23}  moles of Zinc weigh = \frac{63.58}{1}\times 0.16\times 10^{-23}=10.17\times 10^{-23}g

Thus mass of one atom of Zinc weigh 10.17\times 10^{-23}g
