Answer : The value of for is .
Solution : Given,
Solubility of in water =
The barium carbonate is insoluble in water, that means when we are adding water then the result is the formation of an equilibrium reaction between the dissolved ions and undissolved solid.
The equilibrium equation is,
Initially - 0 0
At equilibrium - s s
The Solubility product will be equal to,
Now put all the given values in this expression, we get the value of solubility constant.
Therefore, the value of for is .
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Explanation:
Answer:
The air moves to the low pressure system creating wind.

Answer:
Explanation:
Given parameters:
Mass of water = 40g
Initial temperature = 33°C
Final temperature = 23°C
Specific heat capacity of water = 4.2J/g°C
Unknown:
Quantity of heat = ?
Solution:
To solve this problem, we use the expression below;
H = m c Δt
H is the quantity of heat
m is the mass
c is the specific heat capacity
Δt is the change in temperature
H = 40 x 4.2 x (23 - 33) = -1680J
The water will have to lose 1680J of heat to bring it to that final temperature.
