Choose the correct answer for the following questions: The correct name for CuO

Question

Choose the correct answer for the following questions: The correct name for CuO is Cupric oxide Cuprous oxide Calcium hydroxide None of the above The following reaction is called a hydrogenation reaction: Calculate the enthalpy of the reaction (deltaH^+, for H_2, C_2H_4, and C_2H_6 are O, 52.3 kJ/mol, and 284.7 kJ/mol, respectively.): Is the reaction endo or exothermic? consider the following reaction: What kind of react is it? Precipitation reaction Oxidation reduction reaction Acid base reaction None of the above

Explanation / Answer

1 ) a ) cupric oxide

2) answer : d )

DHrxn   = products enrgy - reactant energy

           = 284.7 - (52.3 + 0)

          = 232.4 kJ/mol

this answer is not given

3)

a ) endothermic

4)

b) oxidation reduction reaction

reason :

Fe+2 (in FeCl2) ---------------> Fe+3 (in FeCl3) -----oxidation

Cl2 (0 ) --------------------------> Cl- (-1) ----reduction
