The rate of evaporation is equal to rate of condensation in equilibrium......It means the evaporation rate becomes constant.....And thus equilibrium attained !!!
Answer:
Volume required from standard solution = 4675 mL
Explanation:
Given data:
Final volume = 75.0 mL
Final molarity = 130 M
Molarity of standard solution = 2.000 M
Volume required from standard solution = ?
Solution:
We use the formula,
C₁V₁ = C₂V₂
here,
C₁ = Molarity of standard solution
V₁ = Volume required from standard solution
C₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula,
C₁V₁ = C₂V₂
2.000 M × V₁ = 130 M × 75.0 mL
V₁ = 9750 M. mL / 2.000 M
V₁ = 4675 mL

Because i comes from cane.
<span>Buffer systems in our
body maintain the pH of blood to be at an optimum level which is at a range of
7.3-7.4. A buffer is a solution that resists changes in pH during the addition
of an acid or a base. Our blood has a number of buffer systems. Examples are
the bicarbonate buffer system and the hemoglobin buffer system.</span>
Answer: Doppler Red-Shift Evidence
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
