When conducting an experiment in the lab, a student was able to actually recover 38.5 grams of Zinc Chloride. Using the balanced chemical equation (2 Zn + CuCl2 ---> 2 ZnCl+ Cu) the student predicted that they theoretically should have been able to make 64.9 grams of Zinc Chloride.

What was the percent yield of this reaction?

What are the first three quantum numbers for the electrons located in subshell 2s?

Balance and in which category does it fit in? single or double displacement or synthesis or decomposition? (a) k2 o → k + o2 (b) na + i2 → nai (c) cu(no3 )2 + naoh → cu(oh)2 + nano3 (d) kclo3 → kcl + o2 (e) ca(no3 )2 + hbr → cabr2 + hno3 (f) sn(oh)2 → sno + h2 o (g) p4 + n2 o → p4 o6 + n2 (h) fe + al2 (so4 )3 → feso4 + al (i) alcl3 + na2 co3 → al2 (co3 )3 + nacl (j) c3 h6 + o2 → co2 + h2 o

In the experiment you asked to react hydrochloric acid and with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision.
