Answer:
change in the total mass of substances
The half-reaction includes either the reduction or the oxidation reaction of the redox reactions. In acidic solution permanganate ion will react with hydrogen ion to yield manganese ion and water.
<h3>What are Redox reactions?</h3>
Redox or oxidation-reduction reactions are the chemical reactions in which the oxidation and the reduction of the chemical species occur simultaneously.
Permanganate (VII) ion is a strong oxidizing agent and gets easily reduced to manganese ion in presence of the hydrogen ion in an acidic solution.
The balanced half-reaction for reduction is shown as,

The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.
<h3>What are organs?</h3>
Organs are a collection of tissues that are closely related and which perform a related function.
The role and function of the organs of the digestive system are as follows:
- Pancreas - produces pancreatic juice which contain digestive enzymes
- Liver - produces bile for the emulsification of fat
- Stomach - serves as a temporary store of food and produces digestive juices
- Small intestine - functions in food digestion
- Large Intestine - helps to remove undigested food from the body
Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

2 moles of Na3PO4 form from 6.0 mol NaOH. Details about stoichiometry can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated stoichiometrically as follows:
3NaOH + H3PO4 → 3H₂O + Na3PO4
According to this equation,
3 moles of NaOH produces 1 mole of Na3PO4
This means that 6 moles of NaOH will produce 6/3 = 2 moles of Na3PO4
Therefore, 2 moles of Na3PO4 form from 6.0 mol NaOH.
