Carbon monoxide is produced in an industrial blast furnace by passing oxygen gas

Question

Carbon monoxide is produced in an industrial blast furnace by passing oxygen gas over hot coal. The balanced equation is: C_(s) + O_2(g) rightarrow CO_2(g) a. How many moles of O_2 react with 2.50 mol of carbon: b. How many moles of CO are produced from 2.50 mol of carbon: Calculate the number of sodium atoms in 0.120 mol Na: Given the following reaction: AlBr_3 + K_2SO_4 rightarrow KBr + Al_2(SO_4)_3 a. What is the number of moles of KBr that will be produced from 42.7 g of AIBr_3 Complete the following equation, then write the completely balanced equation beneath it lithium chloride + lead (II) nitrate rightarrow LiCI + Pb(NO_3)_2 rightarrow

Explanation / Answer

Hi,

10. the balanced reaction is,

C (s)+ O2 (g) ------> CO2 (g)

a. clearly 1 mole of C react with= 1 mole of O2

2.5 mole of C will react with= 2.5*1 moles of O2= 2.5 moles of O2

b. C (s)+ 1/2 O2 (g) -------> CO (g)

clearly,

1 mole of C produces= 1 mole of CO

2.5 mole of C will produce= 2.5*1 moles of CO= 2.5 moles of CO

11. number of sodium atoms in 0.120 mole = 6.023*10^(23)*0.120= 7.228*10^(22) atoms

Thank you
