Answer:
4-ethyl-2,2,6-trimethyl-1-pentylcyclohexane
Answer:
36.0 mL
Explanation:
First, write the balanced reaction.
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Calculate the moles of Ba(OH)₂:
0.500 mol/L × 0.0450 L = 0.0225 mol Ba(OH)₂
Use stoichiometry to find moles of HCl:
0.0225 mol Ba(OH)₂ × (2 mol HCl / mol Ba(OH)₂) = 0.0450 mol HCl
Now calculate the volume needed at the given concentration.
0.0450 mol HCl × (1 L / 1.25 mol) = 0.0360 L HCl
You need 36.0 mL of 1.25 M HCl.

Answer:
B. Add more water to decrease the concentration.
Explanation:
If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.
- Concentration is the amount of solute in a solution.
- Conductivity deals with the ability of a solution to allow the passage of current.
Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.
- Adding more water increases the amount of solvent and the concentration reduces.
