Answer:
It is negative because the enthalpy of the products is greater than the enthalpy of the reactants.
Answer:
B. The reaction would shift to produce more O2 and SO2-
Explanation:
This is because the forward reaction is exothermic.
Answer:
n=6 to n=3 (B)
Explanation:
Energy of an electron present in the orbit is directly proportional to .Hence a transistion from one orbit to another orbit emits an energy proportional to the difference of their squares of the orbits. that is if an electron travels from orbit n1 to orbit n2 then it emits an energy corresponding to .So in the above question the highest energy emission occurs when an electron moves from n=6 to n=3.(Highest difference of energy levels).
<span>As can be seen from the chemical formula, Ca(No3)2 is made up of Calcium, Nitrogen and oxygen. If the appropriate amount of energy is used on the compound, the bonds will disintegrate and the compound will decompose into the individual elements of Calcium, Nitrogen and oxygen</span>
Answer:
Q=7200 W
q=7200/72=100
Explanation:
Given that
ΔT=15° C
Thickness ,t=15 cm
Thermal conductivity ,K=1 W/m.°C
Height,h=6 m
Length ,L=12 m
As we know that heat conduction through wall given as
Now by putting the values
A= 6 x 12 =72
Q=7200 W
Q is the total heat transfer.
Heat flux q
q=Q/A
q=7200/72=100
q is the heat flux.
As w know that heat flux(q) is the heat transfer rate from per unit area and on the other hand heat transfer(Q) is the total heat transfer from the surface.
Heat flux q=Q/A
That is why these both are different.
