Answer:
Explanation:
Both metal and wooden bowls are at the same temperature . But wood is non-conductor of heat whereas metal is conductor of heat .
If we touch the wooden bowl , heat flows from hot to cold object . Since the finger is at higher temperature , heat flows from finger to wooden bowl . But , since wood is non conducting , it does not allow heat to be conducted through it . Hence very less heat will be conducted from our finger .
On the other hand , if we touch a metal bowl , heat flows from finger to the metal bowl , without any hinderance . Hence rate of heat flow will be fast in case of metal bowl . As a result of it , we feel cool in touching metal bowl . This feeling will be absent in case of wooden bowl.
C2H2O4 C2HO4- + H+
0.175 - x x x + y
C2HO4- c2o42– + H+
x - y y x + y
K2 = (y) (x +y) / (x-y)
As, y << x
So, K2 = (y) (x) / (x)
K2 = y =6.1 × 10^–5
Hence, concentration of (c2o42–) 6.1 × 10^–5 M
Explanation:
The resonance compounds are compounds that have the same position of the atoms (same quantity and elements) but the position of the electrons arround them is different in each resonance compound.
In reality, the compound switches between all the resonance structures it has.
One example of resonance Lewis structures is the Ozone's as can be seen in the figure.
