<p>Anyone who has the big dark blue book REAL SAT Subject Tests from college board(not the new one the official study guide for all subject tests or whatever it is) ...</p>
<p>Question # 59.</p>
<p>Which of the following does NOT react with a dilute H2SO4 solution?
A)NaN03
B)Na2S
C)Na3PO4
D)Na2CO3
E)NaOH</p>
<p>The answer's A, but I'm not sure why...
can someone explain it to me please
I know E is a neutralization reaction, and I think D produces CO2 gas and maybe B produces H2S gas, but I'm not sure about the rest.</p>
<p>And also, if someone can explain how to figure out the answers to questions 5,7,8, and 9 I'd really appreciate it :)
Here's the Problem...sorryT.T I don't know how else to put it:</p>
<p>(OH-) + (5) → (CrO4)^2- + (H+) →(6)→
(Ba)^2+ + (Cr2O7)^2- + (H2O) ←(8)←→(7)→(SO2), (H+)→
(BaSO4) + (9) + (H20)</p>
<p>A)CrO7^2-
B)H+
C)OH-
D)Cr^3+
E)Ba^2+</p>
<p>I just plugged answers in and tried balancing the equations, but that took sooo long...</p>
