Answer:
D. 23.9 liters
Explanation:
- Molarity is defined as the no. of moles of solute dissolved in 1.0 L of the solution.
M = (no. of moles)solute / (V of the solution (L))
M = (mass/molar mass)NaCl / (V of the solution (L))
M = 0.03 M, mass of NaCl = 42.0 g, molar mass = 58.44 g/mol.
∴ V of the solution = (mass/molar mass)NaCl / M = [(42.0 g/58.44 g/mol)] / (0.03 M) = 23.96 L.
<em>So, the right choice is: D. 23.9 liters</em>
Answer:D
Explanation:
I’ve had this question before. Since it’s stairs, the potential energy would decrease due to height decrease and it will be transformed to kinetic energy
the answer is fresh water
Answer:
The answer to your question is <u>111 g of CaCl₂</u>
Explanation:
Reaction
2HCl + CaCO₃ ⇒ CaCl₂ + CO₂ + H₂O
Process
1.- Calculate the molecular mass of Calcium carbonate and calcium chloride
CaCO₃ = (1 x 40) + (1 x 12) + ((16 x 3) = 100 g
CaCl₂ = (1 x 40) + (35.5 x 2) = 111 g
2.- Calculate the amount of calcium chloride produced using proportions.
The proportion CaCO₃ to CaCl₂ is 1 : 1.
100 g of CaCO₃ ------------- 111 g of CaCl₂
Then 111g of CaCl₂ will be produced.
