Answer:
125 ml of HCl
Explanation:
The molarity of the stock solution to determine how many milliliters would contain 1.5 moles of HCl. Since a concentration of 12.0 mol/L means that you get 12.0 moles of hydrochloric acid per liter of solution,
Concentration of required HCl (C1) = 1.0M
Volume of required HCL (V1) = 1500 ml
Concentration of stock HCl (C2) = 12M
Volume of stock HCL (V2) = ?
C1V1 = C2V2
V2 = C1V1/C2 = 1*1500/12 = 125 ml
Answer:
covalently
Explanation:
Light shining through the less dense material.
Answer:
1. Temperature
2. Surface area
3. Catalyst
Explanation:
Answer:
Heat, molecular size, and surface area
Explanation:
Heat: higher temperatures are directly correlated to higher kinetic energy. With more kinetic energy, the solute molecules move faster and the bonds are more likely to break.
Molecule size: usually at the same temperature and pressure, the solute with smaller molecular size dissolves faster. A large molecule usually has a heavier weight and size, which makes it more difficult for the solvent to surround it and help break its bonds.
Surface area: increasing surface area generally increases the solubility rate. This is because with a higher area, more molecules are exposed to the solvent, so their bonds are more likely to break.
Answer: 1.00 M
Explanation: The problem can be solved using the formula of dilution which is the product of Molarity and volume M1V1= M2V2.
Derive for M2, so the formula will be M2 = M1V1 / M2
M2 = 2.00 M ( 0.400 L ) / 0.800 L
= 1.00 M
Answer:
1.00 M
