Answer: i think maybe 10.
Explanation:
Explanation:
The total mass of the product will also be 20g because in chemical reactions, mass is always conserved.
According to the law of conservation of mass "the law states that matter can neither be created nor destroyed but changed from one form to another in a chemical reaction".
- The law simply postulates that mass is conserved in chemical reactions.
- If the mass of reactants is 20g, the mass of the products will likewise be 20g.
- So, the mass is the same in both directions.

Explanation:
In the voltaic cell, energy is produced by spontaneous chemical reaction. One half cell functions as the anode (in this case it is the Fe/Fe^2+ half cell) while the other half cell functions as the cathode (in this case it is the the Ag/Ag^+ half cell).
At the anode;
Fe(s) -----> Fe^2+(aq) + 2e
At the anode;
2Ag^+(aq) + 2e ------> 2 Ag(s)
Overall cell equation;
Fe(s) + 2Ag^+(aq) ------> Fe^2+(aq) + 2 Ag(s)
Hello!
This question can be easily solved using the
Mole Ratio of KNO₃/KI in the balanced reaction that is shown below:
2KI + Pb(NO₃)₂ → 2KNO₃ + PbI₂
The Mole Ratio of KNO₃/KI in this reaction is
2 moles KNO₃/ 2 moles KI so we can apply the following conversion factor:
So, if 0,03 moles of KI are completely consumed,
0,03 moles of KNO₃ are formed.
Have a nice day!
