Hi how are you hope you are well i want to say i and mt sister need help with

10 and them 2 are in year 7

help me understand how these two work. I think they both worth by donating hydrogen ions. If a reduction reagent can be used in a reaction, can electrolysis always be substituted in its place because it works by the same mechanism? Also, what is the difference in properties of different reduction reagents. For example magnesium vs zinc, they are both electropositive elemental metals. So will they always react the same but just at different rates?

formula online to help.. It should be a simple straightforward problem but i just can not for the life of me figure it out. are you able to provide me with a formula or point me in the right direction? The problem is: Solution A has a 50% concentration Solution B has a 100% concentration Solution C has a 5% concentration you have 5L of each solution to utilize as well as unlimited quantities of water to dilute solution concentrations if needed. Part A Make a final solution of 100ml with solution concentrations of Solution A 15%, solution C 5% and solution C 80%. how much of each solution will you need to make your final 100ml solution? Part B using the above solutions how many 100ml final solutions can you produce with the 5L volumes? No matter how I work it i can't make the solution to the correct concentrations. Thank you for your help. John
