Glucose, C 6 H 12 O 6 , is used as an energy source by the human body. The overall reaction in the body is described by the equation C 6 H 12 O 6 ( aq ) + 6 O 2 ( g ) ⟶ 6 CO 2 ( g ) + 6 H 2 O ( l ) Calculate the number of grams of oxygen required to convert 58.0 g of glucose to CO 2 and H 2 O .

Answer : The mass of required is, 61.82 grams.

Explanation :

First we have to calculate the moles of

Now we have to calculate the moles of .

The balanced chemical equation is:

From the balanced reaction we conclude that

As, 1 mole of react with 6 mole of

So, 0.322 moles of react with moles of

Now we have to calculate the mass of

Molar mass of = 32 g/mole

Therefore, the mass of required is, 61.82 grams.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
