<p>Does anyone remember the answer to the question about the oxidation number/state -3? I think I put “nitrogen family”.</p>
<p>ya nitrogen family for-1</p>
<p>the one which had valence electrons in the 4th level was oxygen family.</p>
<p>You mean “for -3”, right?</p>
<p>yes -3 typo lol</p>
<p>It was definitely Nitrogen family.</p>
<p>and oxygen family for the 4th level one</p>
<p>@shaheiruddin, I don’t hate you. I just get annoyed at your spelling and insistence that it was 6 unpaired valence electrons.</p>
<p>ionic balance somebody confirm that it was 2.</p>
<p>Definitely. In any ionic compound nitrogen would have a charge of -3, so its oxidation state should be the same for most compounds.</p>
<p>What question are you talking about with the ionic balance?</p>
<p>it seems that most people ommited the ionic balancing problem</p>
<p>I didn’t omit any at all, I just don’t remember what the question was about. Can you give the idea of the question, like what it was asking?</p>
<p>^shaheirruddin
i didnt omit a single question, can you specify what exactly the question was?</p>
<p>I have a feeling he/she might be talking about the last question, where it asked you to balance the equation and then give the ratio.</p>
<p>the ratio i got was 2:3</p>
<p>Ca2+ + (CO3)2- + 2 H+ + 2 Cl- Ca2+ + 2 Cl- + H2O + CO2
or something like that. NOTE: THIS WAS NOT THE ACTUAL QUESTION.</p>
<p>does anyone remember what they put for the balancing equation with the charges</p>
<p>it included stuff like Na, HCO3-, etc</p>
<p>I put 2. It took me forever to get it though!</p>
<p>Are you sure? i think i put down 3, how were you suppose to solve it?</p>
<p>what was the question in the ionic balancing problem? i think that it was just balancing the equation, but i can’t remember the equation, but i remember that there were 3 reactants and 2 products, and Ca+ was a product and CaCO3 was a reactant.</p>
