FILL IN BLANKS PLEASE

The balanced equation

6CO₂ + 6H₂O = C₆H₁₂O₁₆ + O₂

Given

Reaction

CO2 + _H2O = _C6H12O16 + _O2

Required

Balanced equation

Solution

Give a coefficient

aCO₂ + bH₂O = C₆H₁₂O₁₆ + cO₂

Make an equation

C, left = a, right = 6⇒a=6

H, left = 2b, right = 12⇒2b=12⇒b=6

O, left=2a+b, right = 16+2c⇒2a+b=16+2c⇒2.6+6=16+2c⇒2c=2⇒c=1

The equation becomes :

6CO₂ + 6H₂O = C₆H₁₂O₁₆ + O₂

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
