Question

What is the balanced equation? and how to solve..

Answer 1

The balanced equation is
`C_(6) H_(12)O_(6)+6O_(2)` →
`6CO_(2)+6H_(2)O`

The number of grams of oxygen needed to react with 30 grams of glucose is 30 grams.

Step-by-step explanation:

`\frac{30 g(glucose)}{}|(1mol(glucose))/(180.156g(glucose)) |(6mol(oxygen))/(1mol(glucose)) |(32g(oxygen))/(1mol(oxygen))`

The set-up shown is how this problem can be solve. This is called stoichiometry. Stoichiometry refers to math amongst the elements or the compounds. Now, we solve the equation above.

`(5760)/(180.156)`

Divide the expression.

`(5760)/(180.156)` = 31.9722

Now, we round this answer.

31.9722 → 32

The number of grams of oxygen needed is 32 grams.

Hope this helps!
