Answer:
12
Explanation:
alkyne formula is CnH2n-2
heptyne = 7
2NaClO₃ → 2NaCl + 3O₂
mole ratio of NaClO₃ to O₂ is 2 : 3
∴ if moles of NaClO₃ = 12 mol
then moles of O₂ =
= 18 mol
Mass of O₂ = mol of O₂ × molar mass of O₂
= 18 mol × 16 g/mol
= 288 g
So I wasn't sure which equation to use since you did not specify so I just used the decomposition reaction. If you should have used another reaction then just follow the same steps and you'll get your answer.
The answer is covalent bond
An ionic compound is a chemical compound of ions held together by electrostatic forces termed ionic bonding
EXAMPLE -/Sodium chloride ,NaCl with Na+and Ci- ions
