I believe there are three carbon atoms in propane
The pH changes to a value closer to 7, which is considered neutral.
This, however, only applies to all reactions between strong acids and strong bases. If the reaction either involves a weak acid and/or a weak base, the computation of the final pH may slightly be more complicated.
The name for the compound Ag2S is Silver sulfide.
<u>Explanation</u>:
- The name for the compound Ag2S is Silver sulfide. It is the inorganic compound with the formula Ag
2S. A dense black solid, which is used as a photosensitizer in photography.
- Silver sulfide is insoluble in most solvents but is degraded using robust acids where the bonds have a low ionic of approximately 10%.
- It has a molar mass of 247.80 g / mol. The look is the grayish-black crystal, odorless, soluble in aqueous HCN, aqueous citric acid with KNO3 and insoluble in acids, alkalies.
I hope this helps! please tell me if it’s wrong.
Calculate the H positive from the pH equation: pH equals -log (H positive). This would be 10 to the -6.49. Let's call the acid HA. To calculate Ka in this equation, Ka equals H positive times A- over HA. HA is going to be the 0 0121. So, Ka=(10^-6.49)^2/0.0121. This equals 1.05*10^-13/0.0121. Ka then equals 8.65*10^-12.
