The equivalent weight of crystalline oxalic
acid is:

Answers

Answer from: arod20061

126 g/mol

Explanation:

The Formula of oxalic acid is H2C2O4. 2H2O. therefor, the equivalent weight of the acid is molecular weight (126 g/mol) when it is divided by n-factor (valency=2)which would be ,126/2 = 63. h

hope this helped (((: if it did please mark brainliest and have a nice day

Answer from: Quest

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

Answer from: Quest

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.

chemical decomposition is opposite of chemical synthesis.
