The metabolism of glucose (molar mass 180.2 g/mol) with oxygen forms CO2 and H2O and releases 678 kcal/mol of energy. C6H12O6(aq) + 6 O2(g) ⇌ 6 CO2(g) + 6 H2O(l) glucose
a. Are the bonds formed in the products stronger or weaker than the bonds broken in the reactants?
Stronger or weaker?
b. How much energy is released when 6.00 mol of glucose is metabolized?
? kcal
Report answer to appropriate number of significant figures.
The combustion of coal with oxygen forms CO2 and releases 94 kcal of energy.

the metabolism of glucose (molar mass 180.2 g/mol) with oxygen forms CO2 and H2O and releases 678 kcal/mol of energy. C6H12O6 (aq)+ 6 O2(g) <> 6 CO2(g) + 6H2O(l) glucose. how much energy is released when 21.0 g of glucose reacts (? Kcal)
Calculate the grams of the indicated product when 17.9 g of the first reactant and 10.1 g of the second reactant is used:
Al2S3(s)+6H2O(l)→2Al(OH)3(aq)+3H2S(g) (H2S)
Compound A gives positive test with Lucas reagent in 5 minutes.A reacts with PCL5 to Form B. B reacts with chlorobenzene and sodium with ether to form C. C is used for purest preparation of phenol. identify A, Band C.
