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.

Answer:
the funnel with the filter paper
Explanation:
When the mixture of solution is poured through the funnel with filter paper, the liquid solution can pass through the filter paper and gets collected in the beaker (filtrate) while the solid products are too large to pass through the filter paper, so they remain on the funnel (residue).
With this tool, the solid product could be separated from the mixture.
Answer:
SrCl2 + 2AgNO3 ----> Sr(NO3)2 + 2AgCl (solid)
Explanation:
SrCl2 + 2AgNO3 ----> Sr(NO3)2 + 2AgCl (solid)
Hello there.
The answer here is true. Cold objects melt faster in hot water than cold water.
