A teacher wants to figure out the amount of a solution that is needed for a titration experiment in a class lab. The class has 1
5 students, and each experiment needs 50 mL of solution. If each student will perform the experiment two times, how many mL of solution will the teacher need for the whole class?
375 mL
750 mL
1500 mL
3000 mL
Baking soda and vinegar react chemically because one is a base and the other is an acid. Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic acid. ... The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate.
First, we need to balance the chemical reaction first. 4P4 + 5S8 -> 4P4S10 Next, we determine the limiting reactant based on the given amounts of the reactants and the stoichiometric ratio of the reactants. Based on 14.62 mol P4, the P4S10 produced is 16.42 mol P4 (4 mol P4S10 / 4 mol P4) = 16.42 mol P4S10 Based on 2.14 mol S8 2.14 mol S8 (4 mole P4S10 / 5 mol S8) = 1.71 mol P4S10
The maximum amount is 1.71 mol P4S10 since S8 is the limiting reactant.
