The combustion reaction of hexane:
2 C6H14 + 19 O2 = 12 CO2 + 14 H2O
2 mol C6H14 ---------> 12 mol CO2
x mol C6H14 ---------> 18.4 mol CO2
12 * x = 18.4 * 2
12 x = 36.8
x = 36.8 / 12
x = 3.067 moles of CO2
hope this helps!.
Answer:
ZnCO3+H2SO4= ZnSO4+H2CO3
Explanation:
ZnCO3+H2SO4= ZnSO4+H2CO3
<u>Zinc is more reactive than hydrogen, hence, it will displace Hydrogen from Sulfuric acid.</u>
Answer:
The reaction is reactant-favored
Explanation:
If we take a look at the reaction equation, Zn2+ (aq) + Co (s) Zn (s) + Co2+ (aq) and consider the reduction potential of the species involved
Zn^2+(aq)/Zn(s)= -0.76
Co^2+(aq)/Co(s)= -0.28
It can easily be seen that the reduction potential of zinc is more negative than that of cobalt. Hence the electrochemical reaction is not spontaneous as written but will greatly favour the reverse reaction.
kinetic energy kkkkkkkkkk
