Which compound contains both ionic and covalent bonds

1 answer:

Leokris [45]2 years ago

6 0

Answer:

Any compound that contains a metal ion and a polyatomic ion would work. Polyatomic ions are covalently bonded non-metals that have some overall charge. Examples of common polyatomic ions include OH⁻ (hydroxide), NH₄⁺ (ammonium), and NO₃⁻ (nitrate). So answers to this question can be something like KOH (potassium hydroxide), but really, anything works if it contains a metal ion and a polyatomic ion.

What is the percentage by mass of sulphur in Al2(SO4)3[A12SO4 =<br>342g/mol, S = 32]

valentinak56 [21]

Answer: The percentage by mass of sulphur in $Al_2(SO_4)_3$ is 9.36%

Explanation:

Mass percent of an element is the ratio of mass of that element by the total mass expressed in terms of percentage.

${\text {Mass percentage}}=\frac{\text {mass of sulphur}}{\text {Total mass}}\times 100\%$

Given: mass of sulphur = 32 g/mol

mass of $Al_2(SO_4)_3$ = 342 g/mol

Putting in the values we get:

${\text {Mass percentage}}=\frac{32g/mol}{342g/mol}\times 100\%=9.36\%$

The percentage by mass of sulphur in $Al_2(SO_4)_3$ is 9.36%
