The paper in the straw makes the soda fizz.
All chemical reactions have a conversation of mass and energy.
Because:- There are only two laws for conversation in a chemical reaction. The conversation of mass, no mass can be created nor destroyed. Also, the law of conversation of mass states that no energy can be created nor destroyed in a chemical reaction. The charge can obviously change because they can bond and change charges.
1 liter is 1000 grams so 74.4*1000=74400 grams
Answer:
The value of the 
of the acid is :
Explanation:
The pH of the weak acid solution = 3.879
Concentration of hydrogen ions = ![[H^+]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D)
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
![3.879=-\log[H^+]](https://tex.z-dn.net/?f=3.879%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=10^{-3.876}=0.0001321 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-3.876%7D%3D0.0001321%20M)
Concentration of hypochlorous acid solution = [HClO]= 0.426 M
Initially:
0.426 M 0 0
At equilibrium
(0.426-0.0001321)M 0.0001321 M 0.0001321 M
The expression of will be given as;
![K_a=\frac{[H^+][ClO^-]}{[HClO]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BH%5E%2B%5D%5BClO%5E-%5D%7D%7B%5BHClO%5D%7D)
The value of the of the acid is :
The period number of krypton is 4
