Answer : The activation energy for the reaction is, 52.9 kJ/mol
Explanation :
According to the Arrhenius equation,
or,
where,
= initial temperature =
= final temperature =
= rate constant at =
= rate constant at =
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
Now put all the given values in this formula, we get:
Therefore, the activation energy for the reaction is, 52.9 kJ/mol
Answer:Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).

Answer:
i dont think anybody is going to be able to do all of these lol
Explanation:
The rules is that, the more reactive the substance, the harder it is to extract. The reason is mainly due to the fact that you have to find a specific solvent to react the substance only, not the others.Basing on the list of reactivity of metals as shown in the picture, Zn is more reactive than Ag. Then, that means that Ag is easier to recover.
