Answer:
0.16 moles of Carbon
Explanation:
The balanced reaction equation:
+ 
→ 
+ 
↑
The mole ratio of Carbon to Iron is 3 : 4 (since Fe2O3 is in excess)
i.e 3 moles of C produces 4 moles of Fe.
If 1 mole of Fe - 55.8g of Fe
? moles - 11.6g of Fe
= 
= 0.208 moles
But 3 moles of C - 4 moles of Fe
? moles of C - 0.208 moles of Fe
= 
= 0.16 moles of carbon.
I hope this explanation was clear and useful.
Answer:
The pH of the solution is 1.68.
Explanation:
Hope this helped!
Answer:
B. decrease.
Explanation:
Because size of atom increases so it is easy to remove electron
Electrode potential is concentration dependent as it is composed of two half-cells with same electrodes but different concentrations. One acting to dilute a more concentrated solution, while the other concentrates a more diluted solution — which then creates a voltage that is in equilibrium. This why we need both positive and negative sides of a battery as a power source and make something work.
