<u>Analysing the Question:</u>

We are given the balanced equation:

C₆H₁₂O₆ + 6O₂→ 6CO₂ + 6H₂O

from this equation, we can say that: <em>for every 1 mole of Glucose, we need 6 moles of Oxygen</em>

<u>Moles of Glucose used in the reaction:</u>

Molar mass of Glucose = 180 grams / mol

Given mass of Glucose = 1 gram

Mole of Glucose = Given mass / Molar mass

Moles of Glucose = 1 / 180 moles

<u>Mass of Oxygen required:</u>

We know that for every mole of Glucose, we need 6 moles of Oxygen

So, for 1/180 moles of Glucose, we need 6 / 180 = 1 / 30 moles of Oxygen

Mass of 1 / 30 moles of Oxygen:

Mass = Molar mass * number of moles

Mass of Oxygen = 32 * 1/30

Mass of Oxygen  = 32 / 30

Mass of Oxygen = 1.06 grams

Fe+CuCI2&gt; FeCI2+Cu balancing equations
Volgvan

Explanation:

To balance a chemical equation implies that we are conserving the number and mass of the reacting species.

Chemical equations must obey the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".

This suggests that mass is conserved.

The number of atoms on the reactant side must be equal to that on the product end.

Before proceeding, check the species to see if they have equal number of atoms on both sides:

      Fe      +            CuCI₂        →   FeCI₂               +                        Cu

Elements                 reactants              products

  Fe                               1                             1

  Cu                               1                             1

  Cl                                2                              2

We can see that the equation is already balanced
