Which compound contains both ionic and covalent bonds

Chemistry
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 percent by mass of oxygen in table sugar?
BartSMP [9]

51.41%

Percentage Composition from Formulas

A more complex example is sucrose (table sugar), which is 42.11% carbon, 6.48% hydrogen, and 51.41% oxygen by mass.

Or

53.3 %

Thus the % composition of glucose by mass is carbon 40.0 % oxygen 53.3 % hydrogen 6.7 % In this way, the % composition by mass of any compound can be calculated provided that its formula is known.

...

What is the percentage composition of sugar?

Element Symbol Mass Percent

Hydrogen H 6.714%

Carbon C 40.001%

Oxygen O 53.285%
