Answer:
low
Explanation:
We were informed in the question that the student had incorrectly recorded the mass of cup + sample as 2.20 g but inadvertently used 2.00 g in the calculations.
This error will cause a slight decrease in the mass of water and ultimately decrease the number of moles of water in the hydrate.
What i am saying is that the number of moles of water obtained in the calculation will be artificially low.
Answer:
The answer should be Skeptical
Answer:
A balanced chemical equation explicitly provides you with the
a. conditions under which the reaction occurs.
b. molar masses of the reactants and products.
c. conversion factors needed to solve a stoichiometry problem.
d. mole ratios needed to solve a stoichiometry problem.
The correct answer to the question is
d. mole ratios needed to solve a stoichiometry problem.
Explanation:
A chemical reaction is sad to be balanced if it contains the complete list of reactants and products present in their relative proportions. The amounts of reactants and products can be calculated from a balanced chemical reaction equation by applying a process known as stoichiometry
An example of stoichiometry is the formation of two moles of water from one mole of oxygen and two moles of hydrogen
