NO2 (g) + 2 H2O (l) You are given 1.00 g of copper, how much
concentrated nitric acid (in mL) do you need for this reaction?
Concentrated nitric acid is 15.0 M HNO3. Which is the
correct answer:
4.19
6.29

You are given 1.00 g of copper and 5.00 mL of concentrated
nitric acid, how much concentrated nitric acid (in mole)...
Given the reaction: 2 Al (s) + 6 HNO3 (aq) ® 2
Al(NO3)3 (aq) + 3 H2 (g) ..
When 0.143 g of Al were added to 200
mL of 0.500 M HNO3, 0.00842 g of H2
were produced. Find the percent
yield of H2.
(Please don’t forget to calculate the theoretical yield of
hydrogen from both the aluminum and
the nitric acid.)
Reaction 1: Cu(s) + AgNO3 (aq) = CuNO3 (aq) + Ag (s)
Reaction 2: Cu (s) +AgNO3 (aq) = Cu(NO3)2 (aq) + Ag (s)
Part 1: Write the balanced net ionic equations for both of the
above reactions.
Assume that excess silver nitrate is available when answering
