50 grams of acetic acid c2h4o2 are dissolved in 200 g of water. calculate the weight % and mole fraction of the acetic acid in the solution

             

so:







so:



it means that

in of acid there is moles of acid



so:



it means that:

in of water there is moles of water

therefore:



So your answers are:



and the mole fraction is:

C. 1s22s22p63s23p43d104s24p5

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
