When we have Ksp CaSO4 = 9.1x10^-6 so by substitution in Ksp formula:
Ksp CaSO4 = [Ca+2][SO4]
1.9x10^-6 = [Ca+2][1.5x10^-2]
∴ [Ca+2] M in the solution =1.27x10^-4
when percent remaining = [Ca in solution]/[C original value] * 100
= [(1.27x10^-4*(50ml+50ml)]/[1.28x10^-2*50ml]*100
≈ 2%
Answer:
B mixture can be separated by physical means
Answser: a curved line.
Justification:
Boyle's law states that a constant temperature the volume of a certain amount of gas is inversely related to the pressure:<em> pV = k.</em>
The graph of two inverseley related variables is a curve: as one variable increases the other decresases.
In such a curve for any pair of points it is obeyed Boyle's law: pV = constant, so:
<em> p₁V₁ = p₂V₂ = p₃V₃ = ... = k</em>
Mathematically, the graph represents a hyperbola: as the value of one of the variables increase the other trends to zero, so the curve approaches the axis without touching them.
See the figure attached to visualize the form of the curve.
Speed has only magnitude, or number value,
velocity has magnitude and direction.

is an element with a mass number of 58.6934 u <u>+</u> 0.0002 u.
It has a symbol of Ni and an atomic number of 28. Nickels are usually used to
make US coins because it is a silvery-while metal. It was Axel Fredrik
Cronstedt who were said to discover Nickel in year 1751. The melting point is
Nickel is 2 651 degree F or equals to 1 455 degree C. It is also said to be
hard and ductile.</span><span>
