Complete the data table:

use these values:

the atomic mass of al is 27.0 g/mole.

the atomic mass of pb is 207.2 g/mole.

use two significant digits for your answers:

mass of al wire before reaction = 3.96 g

mass of al wire after reaction = 3.65 g

mass of al = g

moles of al lost = moles

mass of pb + filter paper = 4.26 g

mass of filter paper = 0.92 g

mass of pb = g

moles of pb formed = moles

Cucl2 + 2nano3 cu(no3)2 + 2nacl what is the percent yield of nacl if 31.0 g of cucl2 reacts with excess nano3 to produce 21.2 g of nacl? 49.7% 58.4% 63.6% 78.7%

In which reaction is precipitation occurring?

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
