Answer: The given statement is false.
Explanation:
Weight :It is defined as the measure of force exerted upon the object by the gravity. It is measured in Newtons.
, where W= Weight , m = mass of the object , g = acceleration due to gravity =
Here the given statement is False, the correct statement will be:

Explanation:
Step 1: Write the balanced "molecular" equation:
Step 2: H₂S is written in molecular form. Consult the solubility and net ionic equation rules on the information page to determine which of the other substances will dissociate:
yes no yes
Step 3: Dissociate all soluble salts, strong acids, and strong bases (except calcium hydroxide). Leave together all "not soluble" salts and weak acids or bases:
Step 4: Cross out "spectator ions" that appear on both sides of the reaction (these ions do not participate in the chemistry) and rewrite the "net" reaction using the smallest possible coefficients:
