Answer:
Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. Least Common Multiple of 2 and 15 with GCF Formula The formula of LCM is LCM (a,b) = (a × b) / GCF (a,b).
Explanation:
Answer: The 
of 
is 
.
Explanation:
Given: ![[Ag^{+}] = 1.3 \times 10^{-4} M](https://tex.z-dn.net/?f=%5BAg%5E%7B%2B%7D%5D%20%3D%201.3%20%5Ctimes%2010%5E%7B-4%7D%20M)
The reaction equation will be written as follows.
This shows that the concentration of 
is half the concentration of 
ion. So,
![[CrO^{2-}_{4}] = \frac{1.3 \times 10^{-4}}{2}\\= 0.65 \times 10^{-4} M](https://tex.z-dn.net/?f=%5BCrO%5E%7B2-%7D_%7B4%7D%5D%20%3D%20%5Cfrac%7B1.3%20%5Ctimes%2010%5E%7B-4%7D%7D%7B2%7D%5C%5C%3D%200.65%20%5Ctimes%2010%5E%7B-4%7D%20M)
The expression for of this reaction is as follows.
![K_{sp} = [Ag^{+}]^{2}[CrO^{2-}_{4}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%20%3D%20%5BAg%5E%7B%2B%7D%5D%5E%7B2%7D%5BCrO%5E%7B2-%7D_%7B4%7D%5D)
Substitute values into the above expression as follows.
![K_{sp} = [Ag^{+}]^{2}[CrO^{2-}_{4}]\\= (1.3 \times 10^{-4})^{2} \times 0.65 \times 10^{-4}\\= 1.1 \times 10^{-12}](https://tex.z-dn.net/?f=K_%7Bsp%7D%20%3D%20%5BAg%5E%7B%2B%7D%5D%5E%7B2%7D%5BCrO%5E%7B2-%7D_%7B4%7D%5D%5C%5C%3D%20%281.3%20%5Ctimes%2010%5E%7B-4%7D%29%5E%7B2%7D%20%5Ctimes%200.65%20%5Ctimes%2010%5E%7B-4%7D%5C%5C%3D%201.1%20%5Ctimes%2010%5E%7B-12%7D)
Thus, we can conclude that the of is .
Answer:
Geysers are made from a tube-like hole in the Earth's surface that runs deep into the crust. The tube is filled with water. Near the bottom of the tube is molten rock called magma, which heats the water in the tube. ... Its powerful jet of steam ejects the column of water above it.
