<p>I put I and II as well. I thought NO3 wouldnt be the answer</p>
<p>from scale of 1-10, i guess about 5, but i omitted 7 and made about 5 mistakes so far… lol canceling my scores</p>
<p>Why is Na2CO3 both covalent and ionic?</p>
<p>I got 3 CE, but one of those is wrong if the iron one really is FT and not TTCE. In retrospect, it can’t possibly be TTCE because even if statement I is correct, statement II is not a sufficient explanation, so it’s either TT or FT.</p>
<p>on a scale of 1-10 (10 being the hardest) what would u guys rate the test?</p>
<p>Yes quicksilver your correct</p>
<p>tneduts: stop asking that question lol</p>
<p>Barium must contain 56 protons?</p>
<p>sorry >_<
no one’s answering lolol
i’ll stop</p>
<p>Yeah, that’s what I got.</p>
<p>Wait, was Na2CO3 both ionic and covalent or just ionic?</p>
<p>OH SHOOT. I just realized it has to be also covalent… I totally forgot O is also bonded to C covalently.</p>
<p>yes both ironic and covalent</p>
<p>so for the BaSO4 question, the answer is I and II only?
not NO3 right?</p>
<p>^ yes that is correct.</p>
<p>Shoot I guessed that question and my guess was wrong</p>
<p>I’m worried about my calculations. I am terrible at dividing decimals…</p>
<p>I got 56 protons for barium.</p>
<p>i ommitted one, got at least 6 wrong…should i cancel? do colleges see all subject scores?</p>
<p>what was the answer for conjugate acid/base pair one??</p>
<p>I don’t know exactly but I know the pair both had an O</p>
<p>I put h2s and s2-, that was the only pair that made sense, though technically, h2s is a diprotic acid and its true conjugate base would be Hs-.</p>
<p>^ I think it was like HF and F-</p>
