Question

Complete the following questions. You may use your lab manual and report sheets. Be sure to show your work in any computation problem for full credit. 1. 1412.5 mL = ______ L 2. Refer to lab-2 (Measurements & Flame Test) to answer the following question ____ Mercury metal is a liquid at room temperature and has a density of 13.4 g/mL. If you had a beaker with mercury in it which weighed a total of 356.11 g, calculate the volume of the mercury. The empty beaker weighs 41.33 g. Show your calculations. Refer to lab-7 (Reactivity's Jab) to answer the following question --- What would be observed if a of Silver metal (Ag) were added to a solution of Hydrochloric acid (HCl) ?

Explanation / Answer

Question 1.

1 L = 1000 mL

so

1412.5 mL --> 1412.5/1000 = 1.4125 L

Question 2.

Hg metal...

D = 13.4 g/mL

total mass = 356.11 g, find V

mass of Hg = (356.11-41.33) = 314.78 g

D = mass/Vol

Vol = mass/D

Vol = (314.78)/(13.4 )= 23.49 mL

Q3.

Find observation of Ag + HCl

You will expect to dilute Ag(s)

2 Ag(s) + 2 HCl(aq) = 2 AgCl + H2
