What mass of calcium carbonate is produced when 250 mL of 6.0 M sodium carbonate is added to 750 mL of 1.0 M calcium fluoride

Savatey [412]

Given:

Volume of Na2CO3 = 250 ml = 0.250 L

Molarity of Na2CO3 = 6.0 M

Volume of CaF2 = 750 ml = 0.750 L

Molarity of CaF2 = 1.0 M

To determine:

The mass of CaCO3 produced

Explanation:

Na2CO3 + CaF2 → CaCO3 + 2NaF

Based on the reaction stoichiometry:

1 mole of Na2CO3 reacts with 1 moles of Caf2 to produce 1 mole of caco3

Moles of Na2CO3 present = V * M = 0.250 L * 6.0 moles/L = 1.5 moles

Moles of CaF2 present = V* M = 0.750 * 1 = 0.750 moles

CaF2 is the limiting reagent

Thus, # moles of CaCO3 produced = 0.750 moles

Molar mass of CaCO3 = 100 g/mol

Mass of CaCO3 produced = 0.750 moles * 100 g/mol = 75 g

Ans: Mass of CaCO3 produced = 75 g

How does wax dissolve in kerosene

Alona [7]

Answer:

Petroleum fractions of this kind are commonly known as kerosene. We find that such a mixture of acetone and kerosene will dissolve parafiin wax more eifectively and rapidly than any other solvent hitherto known, and that the wax, when dissolved it will remain in liquid condition indefinitely.

Explanation:

i think this is the answer .

What is the number of moles of H2O produced if you combust two moles of CH4 according to the following balanced equation? CH4 +

loris [4]

The combustion of Methane produces CO₂ and water;

CH₄ + 2 O₂ → CO₂ + 2 H₂O

According to balance equation,

1 Mole of CH₄ on combustion give = 2 Moles of H₂O
So,
2 Moles of CH₄ will produce = X Moles of H₂O

Solving for X,
X = (2 Moles × 2 Moles) ÷ 1 Mole

X = 4 Moles
Result:
4 Moles of H₂O is produced on combustion of 2 Moles of CH₄.
