Would it be easier or more difficult (compared to zinc) to recover silver from solution? explain
1 answer:
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.

Hello! Specific heat is the amount of energy required by known amount of substance to raise its temperature by one degree celsius. In our question it is given that 2000J energy when supplied to 125 g of unknown substance raised its temperature by 18 oC. So, The specific heat is calculated as follow;
Answer:
2.89 g/cm^3
Explanation:
Since density equals mass over volume (or also seen as ), simply divide 66.5 grams by 23.0 cm. This will output an answer of 2.89 g/cm^3.
