Answer:
water vapor
Explanation:
the the answer is water vapor
532 mg of hemoglobin
Explanation:
The concentration of hemoglobin in the blood is 15.2 g/dL. It we transform the g in mg and the dL in mL we have the value for the concentration to be 15200 mg / 100 mL.
Knowing the concentration we devise the following reasoning:
if there are 15200 mg of hemoglobin in 100 mL of blood
then there are X mg of hemoglobin in 3.5 mL of blood
X = (15200 × 3.5) / 100 = 532 mg of hemoglobin

The
equation for the photosynthesis reaction in which carbon dioxide and water
react to form glucose is .
The hear reaction is the difference between the bond dissociation energies in
the products and the bond dissociation energies of the reactants
The
reactant molecules have 12 C = O, 12 H - O bonds while the product molecules
have 5 C - C, 7 C – O, 5 H – O, and 6 O = O bonds. The average bond
dissociation energies for the bonds involved in the reaction are 191 for C = O,
112 for H – O, 83 C –C, 99 C – H, 86 C – O, 119 O = O.
Substitute
the average bond dissociation energies in the equation for and
calculate as follows
=
[12 (C=O) + 12 (H-O)] – [5(C-C) + 7(C-H) + 7 (C-O) + 5(H-O) + 6(O=O)]
=
[12x191 kcal/mol + 12x112 kcal//mol] – [5x83 kcal/mol + 7x99 kcal/mol + 7x86
kcal/mol + 5x112 kcal/mol + 6x119 kcal/mol]
=
3636 kcal/mol – 2984 kcal/mol = 652 kcal/mol x 4.184 Kj/1kcal = 2.73x10^3 kJ/mol
So,
enthalpy change for the reaction is 652 kcal/mol or 2.73x10^3 kJ/mol
