Hey there!
Molar mass of CaCl₂:
Add the molar masses of each element multiplied by the amount of that element we have.
Ca: 1 x 40.078
Cl: 2 x 35.453
---------------------
110.98 grams
The molar mass of calcium chloride is 110.98 grams.
Hope this helps!
Answer: The charge on a sulfide ion is –2.
Explanation:
Answer:
It becomes insoluble again.
Explanation:
The chemical equation showing the reaction between benzoic acid, and sodium hydroxide,NaOH is given below;
C6H5COOH + NaOH ------------------------> C6H5COO^- Na^+ + H2O.
The Benzoic acid, C6H5COOH is insoluble but when it reacted with 1M Sodium hydroxide, NaOH it changes to sodium benzoate, C6H5COO^- Na^+ which is more soluble than the benzoic acid.
C6H5COO^- Na^+ + HCl -------------------> C6H5COOH + NaCl.
When the sodium benzoate, C6H5COO^- Na^+ reacts with 6M HCl, it is converted back to benzoic acid which is insoluble. Hence, precipitation is observed.
