Answer 1

The balanced reaction is

a. 2AgNO3 + Na2CO3 = Ag2CO3 + 2NaNO3

ans is 2,1,1,2

b. moles of Na2CO3 = 10g / 105.9888 g/mol = 0.094

moles of AgNO3 = 10g / 169.87 g/mol = 0.058

hence, silver nitrate is limiting reagent.

c. two moles of silver nitrate produce 2 moles of sodium nitrate.

hence moles of sodium nitrate formed = 0.058

mass of sodium nitrate formed = 0.058 moles *84.9947 g/mol = 5.004 g

d. two moles of silver nitrate gives 1 mole of silver carbonate

hence moles of sodium carbonate formed = 0.058

mass of sodium carbonate formed = 0.058 moles *167.8771 g/mol = 10.008g
