Answer:
Kc = [CO2], that is to say it is equal to the concentration of CO2
Explanation:
It is a heterogeneous equilibrium since the substances that participate in the reaction are in different phases
In the heterogeneous limestone decomposition reaction:
CaCO3(s) --> CaO(s) + CO2(g)
The equilibrium constants are:
Kc = [CO2(g)]; Kp = PCO2(g); Kc = Kp (R T)^
−(1−0) = Kp (R T)^
−1
The equilibrium situation is not affected by the amount of solid or liquid, as long as these substances are present.
The equilibrium constant is independent of the amounts of solids and liquids in equilibrium.
Answer:
C. C
Explanation:
The heating curve is a graphical representation shows that how different phases of substances change as it is influenced by the increase in temperature or heat.
Section A represents solid phase, Section B represents solid-liquid phase, section C represents liquid phase, section D represent liquid-gas phase and section E represents gas phase.
Section C of the graph shows the liquid phase of the substance gaining kinetic energy. During Phase C, heat energy is absorbed and liquid particles gain kinetic energy to change into gas form that is section E.
Hence, the correct option is C.C.
Answer:
Aluminium Can not rust (Can't rust also meaning <u>Corrode)</u>
Because it's surface is protected by aluminium Oxide which stops the metal below from coming in contact with the air (which contains Oxygen) Unlike rust, which can flake off the surface of iron and steel objects, the layer of aluminium oxide does not flake off.
<u>Corrode</u>
<u>destroy or damage (metal, stone, or other materials) slowly by chemical action.</u>
