Answer:
1. decomposition
2. combustion
3.single replacement
4. combination
5. double replacement
Explanation:
1. one compound is split into 2 elements
2. co2 and h20 was the product of the reaction
3. cu is replaced with co
4. 2 compounds become one compound
5. ca is replaced with na and na is replaced with ca
Answer:
11.74
Explanation:
The formula to find the pH of a solution is..
pH = -log [H⁺]
pH = -log [1.8×10¹²]
pH = 11.74
The answer would be to 2 decimal places because the concentration is two significant digits.
Answer:
Ksp = 0.0036.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the Ksp of the silver acetate, by knowing that its equilibrium expression is:
![Ksp=[Ag^+][CH_3COO^-]](https://tex.z-dn.net/?f=Ksp%3D%5BAg%5E%2B%5D%5BCH_3COO%5E-%5D)
Next, we calculate molar concentration of the ions in the solution, the same to that of the acetate ions, due to the 1:1 mole ratio, as follows:
![[Ag^+]=[CH_3COO^-]=\frac{1.0g/(166.9122 g/mol)}{0.1000L} =0.0600M](https://tex.z-dn.net/?f=%5BAg%5E%2B%5D%3D%5BCH_3COO%5E-%5D%3D%5Cfrac%7B1.0g%2F%28166.9122%20g%2Fmol%29%7D%7B0.1000L%7D%20%3D0.0600M)
Therefore, the Ksp is:
