Answer:
The chemical formula of the ascorbic acid is .
Explanation:
Empirical formula is the simplest chemical formula which tells the whole number of atoms of each element present in the compound.
The pseudo-formula of ascorbic acid =
In order to determine the empirical formula divide each number of atoms of every element with the smallest number of atoms present in the given formula.
The chemical formula of the ascorbic acid is .
Answer:
0.050 mol
Explanation:
The reaction that takes place is:
Then we convert 0.050 moles of phosphoric acid into moles of ammonium phosphate, using the stoichiometric coefficients of the reaction:
Thus, the complete reaction of 0.050 moles of phosphoric acid would produce 0.050 moles of ammonium phosphate.
Answer:
The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:
Explanation:
The reaction :
Balancing of reaction in an acidic medium:
Step 1: Balance the atoms in the reaction:
Step 2: Balance oxygen atom by adding water on the side where no oxygen or less oxygen atom is present;
Step 3: Balance the hydrogen atom by adding hydrogen ions on the side where water is absent:
Step 4: Now balance charge by adding electrons on the side where more positive charge is present
