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

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
