A student measured the conductivity of a sucrose solution and an unknown solution. When measuring the conductivity of the solutions the conductivity value for sucrose was 0.007 and the
value for the unknown solution was 0.0002. Which of the following would be the best description
of the unknown solution?
Strong Acid
Soluble ionic compound
Strong electrolyte
Nonelectrolyte

Name the element in group 17, period 2. (periodic table)

Draw any one of the skeletal structures of a 2° alkyl bromide having the molecular formula of c6h13br and two stereogenic centers. indicate chirality by using wedge and hashed wedge notation. lone pairs do not need to be shown.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
