Bismuth oxide reacts with carbon to form bismuth metal. when 414 g ot bismuth oxide react with excess carbon, how many moles of bi form

1.78 mol. When 414 g of bismuth oxide react with excess carbon, 1.78 mol of bismuth form .

a)Start with the balanced chemical equation

2Bi2O3 + 3C → 4Bi + 3CO2

b)Convert grams of Bi2O3 to moles of Bi2O3

Moles of Bi2O3 = 414 g Bi2O3 x (1 mol Bi2O3/465.96 g Bi2O3) = 0.8885 mol Bi2O3

c)Use the molar ratio of Bi:Bi2O3 to convert moles of Bi2O3 to moles of Bi

Moles of Bi =0.8885 mol Bi2O3 x (4 mol Bi/2 mol Bi2O3) = 1.78 mol Bi

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
