Soluble means it can be dissolved
Insoluble means it can't be dissolved
Answer:
No it is a poor conductor of heat but is a fair conductor of electricity
Explanation:
Answer:
11.58 g
Explanation:
First we convert the given masses of both reactants into moles, using their respective molar masses:
- 6.89 g CaO ÷ 56 g/mol = 0.123 mol CaO
- 13.79 g H₂O ÷ 18 g/mol = 0.766 mol H₂O
As<em> 1 H₂O mol reacts completely with 1 CaO mol,</em> and there are more H₂O moles than CaO moles, water is the non limiting reactant.
We calculate the mass of the reacting moles of water (the same number of CaO moles, 0.123):
- 0.123 mol H₂O * 18 g/mol = 2.21 g
Finally we <u>calculate how many grams of water remained after the reaction</u>:
- 13.79 g - 2.21 g = 11.58 g
Answer:
1 mole
Explanation:
Given parameters:
Mass of sulfur = 32.066g
Unknown:
Number of moles of sulfur = ?
Solution:
The number of moles of sulfur can be determined using;
Number of moles =
Molar mass of sulfur = 32g/mol
Number of moles = = 1 mole
