Answer:
i have no answer for part A
part B
the one that has a 4 can be divided by 2 because reducing
part c
you can determine if an equation is written in the correct way by balancing the equation as if it had not been done already.
Adding a volatile liquid in the Erlenmeyer flask will increase the total pressure inside the flask. This is because inside the flask, there will be two components: the vapor and the liquid. Each of which will exhibit or exert their own pressure. Thus, the answer to this item should be false.
The theoretical yield of BaCO3 is 5.5
<h3>What is theoretical yield?</h3>
The theoretical yield is the yield calculated from the stoichiometry of the reaction. The equation of the reaction is;
Ba(NO3)2(aq) + Na2CO3 (aq) ------> BaCO3(s) + 2NaNO3(aq)
Number of moles of limiting reactant: 0.4 M × 70/1000 = 0.028 moles
Since the reaction is 1:1,om;y 1 mole of BaCO3 is formed. Hence, mass of BaCO3 = 0.028 moles × 197 g/mol = 5.5g
