How do you find the oxidation number of #SO_4^(-2)#? - Socratic
2016年6月22日 · Since sulfate ("SO"_4^(2-)) is already ionized, its charge is its oxidation state. So it's kind of pointless to find the "oxidation state" for "SO"_4^(2-) because it's already given. The oxidation states for sulfur and oxygen atom are determined from: electronegativities total charge "SO"_4^(2-) has a total charge of -2, and oxygen is more ...
Cr2O7^2- +SO3^2-=Cr^3+ +SO4^2- Balance the ionic equation?
2018年5月22日 · Step 1: Separate the skeleton equation into two half-reactions. #"Cr"_2"O"_7^"2-" → "Cr"^"3+"# #"SO"_3^"2-" → "SO"_4^"2-"#
What is the oxidation state of each element in #SO_4^(2-)
2017年3月4日 · The sulfate ion #SO_4^-2# has a charge of -2 . so # S + 4xx O = -2 #. Oxygen is almost always -2 in charge in order to achieve the stable electron configuration of Neon substituting -2 for O gives
What compound forms between Fe^(3+) and SO_4^(2-)? What is …
2017年2月26日 · In order to show that the iron cation carries a 3+ charge, you must use Roman numerals. In this case, you will have "Fe"^(3+) -> the iron(III) cation The (III) Roman numeral shows that the cation carries a 3+ charge. The anion is called sulfate, which means that the resulting ionic compound will be "Fe"_ 2("SO"_ 4)_ 3 -> iron(III) sulfate
What are the resonance structures for SO_2? - Socratic
2015年2月9日 · Sulfur dioxide, or SO_2, has two resonance structures which contribute equally to the overall hybrid structure of the molecule. However, a third Lewis structure can be drawn for SO_2 which is more stable in theory, but doesn't quite match experimental data. Let's draw the first two Lewis structures for SO_2. The total number of valence electrons we have at our disposal is 18 - 6 from sulfur ...
What is the ionic compound formula of sodium sulfate? - Socratic
2014年5月5日 · Sodium Sulfate is an ionic compound formed by two ions, Sodium Na^+ and Sulfate SO_4^-2. In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion. This will make the formula for Sodium Sulfate Na_2SO_4. I hope this was helpful. SMARTERTEACHER
K2Cr2O7 + H2SO4 + SO2 = K2SO4 + Cr2(SO4)3 - Socratic
2018年5月5日 · Warning! Long Answer. Here's what I get. > The balanced equation is "K"_2"Cr"_2"O"_7 + "3SO"_2 + "H"_2"SO"_4 → "Cr"_2("SO"_4)_3 + "K"_2"SO"_4 + "H"_2"O" I think you ...
Balance the chemical equation FeSO4 - Fe2O3+SO2+SO3 - Socratic
2018年5月29日 · #color(purple)(+4)# in #stackrel(color(purple)(bb(+4)))(bb("S"))stackrel(-2)("O")_2# by two and therefore some of the sulfur atoms have been reduced. The total increases in oxidation numbers shall be the same as the sum of decreases in oxidation numbers in a balanced redox reaction.
What is the conjugate acid and base of #HSO_4^-#? - Socratic
2016年6月27日 · Here's what I got. The thing to remember about conjugate acids is that they are the chemical species that is formed when a Bronsted-Lowry base accepts one proton, "H"^(+). This means that in order to find the conjugate acid of a substance that can act as a Bronsted-Lowry base, all you have to do is add a proton to it. But keep in mind that a proton carries a 1+ charge, so make sure that you ...
What is the formal charge of SO2? - Socratic
2015年12月15日 · The formal charge on the "SO"_2 molecule is zero, but the formal charge on each atom depends on the Lewis structure that you draw. > You can draw three Lewis structures for "SO"_2. The actual structure is therefore a resonance hybrid of all three structures. In calculating the formal charge, each atom "gets" all of its lone pair electrons and half of its bonding electrons. The formal charge is ...
