As Scientist B did the experiment incorrectly tht is Gretchen measured out 5 grams of aluminum and heated it with excess fluorine gas.
<h3>What is the stoichiometry in chemistry?</h3>
Chemical Stoichiometry refers back to the quantitative look at of the reactants and merchandise concerned in a chemical reaction. The word “ stoichiometry” is derived from the Greek word “stoikhein” which means detail and “metron” which means measure.
- As scientists used the insufficient amount of Al due to which weight of Al2O3 is not found ane caused the high error.
- It includes stoichiometry to show how the scientist can make the experiment correct by the production of 19 g of ALF3 which is 26.98 x 19 / 83.98 g of Al.
- so the mass is 610 g of Al that would be the correct amount.

Explanation:
Boiling point is defined as the point at which liquid state and vapor state of a substance are existing in equilibrium.
Equilibrium is defined as the state in which rate of forward and rate of backward reaction are equal to each other.
For example, 
So, when we boil bromine which is present in liquid state then at the boiling point its vapors will exist in equilibrium. And unless all the liquid state of bromine will not convert into vapors its temperature will not change.
Therefore, we can conclude that at boiling point the liquid and the vapur of Bromine are in equilibrium.
Full moon
A lunar eclipse can occur only at full moon. A total lunar eclipse can happen only when the sun, Earth and moon are perfectly lined up — anything less than perfection creates a partial lunar eclipse or no eclipse at all.
Answer:
According to the World Economic Forum, air pollution was found to be the largest current environmental threat to our public health. Up to 52,000 people die every year in the United States alone because of exposure to emissions from power plant emissions.
Answer:
