Answer:
When experiments are carried out or research is done in a certain field of knowledge the scientist at first hypothesise certain knowledge or make theoretical hypotheses about that field of knowledge.
And then conduct the experiment or research to derive certain conclusions and get answers which they can apply on the hypothesis made or on the previous knowledge they have and thereby confirm or negate the hypothesis.
When two scientists are working on similar experiment and they tend to differ in the conclusions drawn by the result, as they get from experiment then it is called as confirmation bias among the scientists.

Explanation:I come back with an asnwer for you
Answer: 10 grams of Hydrogen gas will be produced theoretically.
Explanation: The equation for the reaction between zinc metal and hydrochloric acid is:
As HCl is present in excess, therefore limiting reagent is Zinc metal as it limits the formation of product.
By stoichiometry,
1 mole of Zinc metal produces 1 mole of Hydrogen gas, therefore
Amount of Hydrogen gas produced can be calculated by:
Molar mass of Hydrogen = 2 g/mol
Mass of hydrogen gas produced = (5 moles )× (2 g/mol)
Mass of hydrogen gas produced = 10 grams
