    Need it done within the next two hours. You just have to do the five discussion questions. I presume these are pre-lab questions, if you need any numbers from the actual lab to do any of the questions, just skip them and let me know thanks.

    I can do it ^^

    I'll just add stuff here then

    ---------- Post added at 07:36 PM ---------- Previous post was at 07:26 PM ----------

    1) HCl(aq) + NaOH(aq) ------------> H2O(l) + NaCl(aq)
    2NaOH + H2SO4 --> Na2SO4 + 2H2O

    2) H+(aq) + OH-(aq)---------->H 2 O(l)
    It's the same for both

    If you use 1mL for when measuring out the HCl
    3) 1ml x .1mol/L x 1L/1000mL = 0.0001 mol

    Note: if you use a different mL about, just change the first number

    4) For this, you need to know the actual volume you used

    5) It's a 1:1 ratio for moles of HCl to NaOH. So theoretical is the same number as number 3.
