I believe the correct answer from the choices listed above is the third option. It would be chromium (Cr) that is a transition metal. The 38 elements in groups 3 through 12 of the periodic table are called "transition metals<span>". Hope this answers the question. Have a nice day.</span>
Yes, they both contain chemicals
A neuron has 4 basic part the dendrites the cell body
I think the answer is b.the cell body
but the brain is made up of about 86 billion nerve cells also called neuron
Answer:
Explanation:
Boyle believed that chemistry – the behavior of substances – could be explained through the motion of atoms, which in turn could be understood through mechanics – Galileo's mathematics of motion. Boyle was ultimately proved correct, because today we can understand chemistry mathematically, through quantum mechanics.
According to the reaction equation:
PbCrO4 ↔ Pb2+ + CrO42-
so, when the Ksp expression = [Pb2+] [CrO42-]
when the Ksp =2.8 x 10^-13
when the solubility is the amount of solute that dissolved in a unit volume of a solvent so, we can assume solubility = X
by substitution on Ksp expression:
∴2.8 x 10^-13 = X*X
∴X = √(2.8 x 10^-13)
= 5.29 x 10^-7 M
∴ the solubility = X = 5.29 x 10^-7
