Answer:
Mass of the substance, grams
86.8
Molar mass of the substance
18.0
Molar mass details
2.0160 H (2*1.008) + 15.9990 O (1*15.999)
Answer:
![Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BHCOO%5E-%5D%7D%7B%5BHCOOH%5D%7D)
Explanation:
Hello,
In this case, the weak ionization reaction for formic acid is:
In such a way, we simply recall the law of mass action in order to represent the weak ionization constant, Ka, for such process, by taking into account that the concentration of products is divided over the concentration of reactants as shown below:
Best regards.
Answer:
The over all reaction will be, Fe+CuSO4=======>FeSO4 +Cu. The blue colour of copper sulphate will gradually disappear and at the end of the reaction, the solution will attain a pale green colour due to the formation of Ferrous ion
