Answer: An Arrhenius acid is a type of substance yields hydrogen ions, 
, in an aqueous solution.
Explanation:
Substances that give dissociate to give hydrogen ions or protons when dissolved in an aqueous solution are called Arrhenius acid.
For example, HCl is a strong acid and upon dissociation in water it gives the following ions.
Thus, we can conclude that an Arrhenius acid is a type of substance yields hydrogen ions, , in an aqueous solution.
<span>One theory that explains why scientific theories grow stronger over time is because more scientists study and work on the theory. Over time as the theory is studied in greater depth it becomes more accepted.</span>
Answer:
- 4.5+2.34= 6.84
- 4.5-5 =-0.5
- 6.00+3.411= 9.411
- 3.4×2.32 = 7.888
- 7.77/2.3= 3.37
7. 1200×23.4=28080
9. = 78.512
10. =341.199
11= 7.45

Answer:
1.52V
Explanation:
Oxidation half equation:
2Al(s)−→2Al^3+(aq) + 6e
Reduction half equation
3Sn2^+(aq) + 6e−→3Sn(s)
E°cell= E°cathode - E°anode
E°cathode= −0.140 V
E°anode= −1.66 V
E°cell=-0.140-(-1.66)
E°cell= 1.52V
