Answer:
I think it would be a solution..
But I'm not sure.
I think that because you said before before blending.
Geothermal energy is the thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet and from radioactive decay of materials
Answer:
Chemical change
Explanation:
Matter changes into a new substance by changing into a chemical change. In a chemical change, the substance cannot be changed back to its previous state and a new substance is formed.
Answer:
0.04 M is the lowest concentration of chloride ions that would be needed to begin precipitation.
Explanation:
Concentration of lead nitarte = ![[Pb(NO_3)_2]=0.010 M](https://tex.z-dn.net/?f=%5BPb%28NO_3%29_2%5D%3D0.010%20M)
1 Mole of lead nirate gives 1 mole of lead ion.
Concentration of lead ion in the solution = 
Concentration of chloride ions = ![[Cl^-]](https://tex.z-dn.net/?f=%5BCl%5E-%5D)
The value of ![K_{sp} for [tex]PbCl_2= 1.6\times 10^{-5}](https://tex.z-dn.net/?f=K_%7Bsp%7D%20for%20%5Btex%5DPbCl_2%3D%201.6%5Ctimes%2010%5E%7B-5%7D)
![K_{sp}=[Pb^{2+}][Cl^{-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BPb%5E%7B2%2B%7D%5D%5BCl%5E%7B-%7D%5D%5E2)
![1.6\times 10^{-5}=0.010 M\times [Cl^{-}]^2](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E%7B-5%7D%3D0.010%20M%5Ctimes%20%5BCl%5E%7B-%7D%5D%5E2)
![[Cl^-]=0.04 M](https://tex.z-dn.net/?f=%5BCl%5E-%5D%3D0.04%20M)
0.04 M is the lowest concentration of chloride ions that would be needed to begin precipitation.
