Answer: Theoretical yield of produced by 8.96 g of S is 33.6 g
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of produce = 3 moles of
Thus 0.28 moles of will produce= of
Mass of
Thus theoretical yield of produced by 8.96 g of S is 33.6 g
Answer:
c. 1.5 mol
Explanation:
- Firstly, we need to calculate the no, of moles of 39.0 grams of calcium fluoride.
n = mass / molar mass = (39.0 g) / (78.07 g/mol) = 0.499 mol ≅ 0.5 mol.
- CaF₂ ionized in water as:
<em>CaF₂ → Ca⁺² + 2F⁻.</em>
Every 0.1 mole of CaF₂ is ionized to 3 ions (1 ion of Ca⁺² and 2 ions of F⁻).
<em>So, 0.5 mol of CaF₂ will contain (3 x 0.5 mol = 1.5 mol) of ions.</em>
Thus, the right choice is "c. 1.5 mol".
Answer:
1) Pure water can conduct electricity because a small proportion of its molecules dissociate into ions . The two ions formed in water are, hydrogen ions, H +, and hydroxide ions, OH -.
2) dynamic equilibrium

Answer:
1-hexene. is your answer.
Yes the water boils but it doesn't become water gas it becomes just gas also known as evaporation
