Question

You are asked to weigh 2 g of lithium and add it to 1500 ml of distilled water +2
drops of indicator, knowing that the density of water is 1 at room temperature
while conducting this experiment.

-a-What does stoichiometry mean?
-b-Is it safe to conduct this experiment in the lab, and why ?
-c-‘Describe the characteristic features of the Li that are reflecting its group,
and name the group, and determine its density.

-d-What indicator will you add in the water and what will happen in the
color of the water after adding the 2 g of Li? Explain your answer.
