1. Choose one of the unbalanced chemical equations below.
2. Complete the table based on the unbalanced
chemical equation you chose.
OCH, + 02 -> CO, +H2O
OH, + N2 -> NH,
Al + 02 -> A1,0
O Fe,0, +C -> Fe + COn

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
