Answer:
Places near the Equator experience little seasonal variation. They have about the same amount of daylight and darkness throughout the year. These places remain warm year-round. Near the Equator, regions typically have alternating rainy and dry seasons.
Explanation:
Answer:
C2= 0.16M
Explanation:
C1= 2M, V1= 20ml, C2= ?, V2= 250ml
Applying dilution formula
C1V1= C2V2
2×20 =C2×250
C2= 0.16M
Answer: The value of the equilibrium constant is 0.000023.
Explanation:
Equilibrium concentration of =
Equilibrium concentration of =
Equilibrium concentration of =
Equilibrium concentration of =
The given balanced equilibrium reaction is,
The expression for equilibrium constant for this reaction will be,
Thus the value of the equilibrium constant is 0.000023.
