Answer is: glucose or galactose <span>give up an electron and they are oxidized, usually to acid.
</span>Benedict's reagent <span> is a mixture of </span>sodium citrate, sodium carbonate (Na₂CO₃)<span> and </span>copper(II) sulfate (CuSO₄).
When Benedict's reagent is <span>mixed and heated with glucose and galactos, the copper accept the electrons and become reduced. </span><span>Benedict's test detects the presence of </span><span>aldehydes in solution.</span>
I believe it is: The Law of Reflection says that the angle of incidence and the angle of reflection must be equal.

A. N₂ (g) + 3 H₂ (g) --> 2 NH₃ (g)
B. The value for standard enthalpy of formation is empirical given that the reactants involved were pure elements. So, you can search this on the internet or in any textbook. The Hf for NH₃ is -46.0 kJ/mol.
C. C (s) + O₂ (g) --> CO₂ (g)
D. The Hf for CO₂ is <span>-393.5 kJ/mol
E. 4 Fe (s) + 3 O</span>₂ (g) --> 2 Fe₂O₃ (s)
F. The Hf for solid Fe₂O₃ is -826.0 kJ/mol.
G. C (s) + 2 H₂ (g) --> CH₄ (g)
H. The Hf for methane gas is -74.9 kJ/mol.
