Answer:
The molarity is 90 M
Explanation:
Molarity is a measure of concentration that indicates the amount of moles of solute (in this case CaCl2) in 1 liter of solution (1000ml). In this case we calculate it that way:
200 ml solution ------18 mol CaCl2
1000ml solution----------x= (1000ml solutionx18 mol CaCl2)/200 ml solution
x=<em>90 mol CaCl2---> the solution is 90 M</em>
Answer: The basicity of the salt anion
Explanation:
All the weak acid is neutralized at the equivalence point and transferred to its conjugate base (number of moles of H+ = increased number of moles of OH–). Therefore the solution produced is weakly alkaline and the pH of the equivalence point will be greater than 7.
Answer:
B
Explanation:
Generally, when you dilute something, your goal is to thin your concentration. Even if you added a solute, if your goal is dilution, it will make the concentration decrease.
Answer: Option C is not a property of a acid, acids turn blue litmus paper red.
Explanation:
Answer:
Because glaciers are so sensitive to temperature fluctuations accompanying climate change. so if it gets hotter then the ice glaciers will melt.
