Answer:
the second answer
Explanation:
just multiple 10²=10×10=100×7.6=760g
Keep in mind that when two moles of potassium chlorate are decomposed, 3 moles of oxygen are produced.Think of the coefficients: since the mole ratio is 2 to 3, it means that<span> 2 mol KClO3 will turn into 3 mol O2.
</span>
2kclO3->2kcl+3O2
Answer:
2 moles
Explanation:
For a mole NaCi, we have a mole of sodium ion and a mole of chloride.
The correct answer would be the fourth option. Hydrochloric acid has a higher boiling point than fluorine molecule because the former is a polar molecule which means that it has stronger bonds than fluorine which is a non-polar molecule. Stronger bonds require more energy to break these bonds.
Electrons uniting with electrons of another atom is the cause in this relationship. The effect is a chemical change.
