Answer:
We need 375 milliliters of 0.100 M NaHCO3 solution
Explanation:
Step 1: Data given
Initial molarity NaHCO3 = 0.100 M
Volume prepared solution = 750.0 mL
Molarity prepared solution = 0.05 M
Step 2: Calculate initial volume
C1*V1 = C2V2
⇒with C1 = the initial concentration = 0.100 M
⇒with V1 = The initial volume = TO BE DETERMINED
⇒with C2 = the new concentration = 0.0500M
⇒with v2 = the new volume = 750.0 mL = 0.750 L
0.100 M * V1 = 0.0500 M * 0.750 L
V1 = (0.0500M * 0.750L)/0.100 M
V1 = 0.375 L = 375 mL
We need 375 milliliters of 0.100 M NaHCO3 solution
Answer:
Table salt is considered to be a compound because it is made up of two elements (sodium and chloride,) while sodium itself is a raw element. That's why table salt is considered to be a compound, while sodium is not.
Hope this helped, have a nice day! :)

Answer: a) 0.0144mol/L
b) 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as 
The equation for the ionization of the 
is given as:
We are given:
Solubility of = 
Molar Solubility of = 
1 mole of gives 1 mole of 
and 2 moles of 
ions
Solubility product of = ![[Pb^{2+}][Cl^-]^2](https://tex.z-dn.net/?f=%5BPb%5E%7B2%2B%7D%5D%5BCl%5E-%5D%5E2)
![K_{sp}=[0.0144][2\times 0.0144]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5B0.0144%5D%5B2%5Ctimes%200.0144%5D%5E2)
Thus the solubility product constant is
