you are right. It is Na2HPO4 + HI ==> NaI + NaH2PO4 for which the net ionic equation is HPO4^- + H^+ ==> H2PO4^- Can you explain how to get this, though? any steps would be helpful.
I need to derive a net ionic equation after balancing: NA2PO4 (2-) +HI =? what I have so far is NA2Po4 +2HI = 2NAI +H3PO4 I can't get any farther but the answer is HPO4 (2-) +H =H2PO4 can someone help me with the steps?

I need help on a problem thats on formula for circumference. A circle has a circumference of 36 cm. find it's radius .but it says give an exact answer in simplest form and it says enter pi for the symbol of pie .
You don't need to do a balanced equation for this one. 2.5x =.100(.50) x=.020 this would be 20 ml the formula is Liters x Molarity =Moles so 2.5Molar times x # of liters =.100 x.50 answer is 20ml
molarity x liters = moles you would need to know how many moles or liters to use the above formula. How much NAOH are you being asked to find molarity for?
I don't know if I should be posting this on a new session or just the old one; I asked it yesterday and I have not seen a reply I have: the half life of U-238 is 4.5 x 10^9 yr. A sample of rock of mass 1.6g produces 29 disintegrations per second. find percent by mass of U-...
actually David is right. I forgot the decimal place from the 22 so it is 54.5 amps
E= I x R is the formula the answer is .5454 I=amperes R=ohms E=volts 12volts/22
