Answer:
B) Ksp = 3.7 E-11
Explanation:
CaF2 ↔ Ca2+ + 2F-
S S 2S,,,,,,,,,,,,,,,in the equilibrium
⇒ Ksp = [ Ca2+ ] * [ F- ]²
⇒ Ksp = S * ( 2S )²
⇒ Ksp = 4S³
⇒ Ksp = 4 * ( 0.00021 )³
⇒ Ksp = 4 * 9.261 E-12
⇒ Ksp = 3.704 E-11
Answer:
The answer is D.
Explanation:
Hold the styrofoam ball at arm's length from the eye.
Since the iron is pure, we can look up its density value online and will always be true. This density value of iron is 7.87g/L. Now, we can use the density formula (D = m/V) and rearrange it to solve for V. This new equation is then V = m/D. Next, we plug in our known values and solve for V (5.00g/7.87g/L). This gives us our final answer of 0.635L (three sig figs due to the three sig figs in the provided mass).
Hope this helps!
Answer:
A mineral is an inorganic solid substance formed naturally in the ground having a definite physical and chemical properties.
The internal atomic structure or arrangmenet of atoms of a mineral determines the chemical and physical properties of the mineral.
For example: diamonds and graphite, atmoic structure of diamond is rigid tetrahedral network providing chemical and physical properties of diamond.
