Jul 14, 2014 · +5 Excellent question! I love oxidation state questions. First, let's look at the "K" (potassium). In an ionic compound, the potassium's oxidation state is always +1. Next, let's look at the chlorate , "ClO"_3^-. The charge on the polyatomic ion is -1. You may be asking yourself, how do I know its charge will be -1? Since the entire compound "KClO"_3 has a charge of 0 and the "K" will have a ...

May 9, 2014 · You follow a systematic procedure to balance the equation. > Start with the unbalanced equation: "KClO"_3 → "KCl" + "O"_2 A method that often works is to balance everything other than "H" and "O" first, then balance "O", and finally balance "H". Another rule is to start with what looks like the most complicated formula. The most complicated formula looks like "KClO"_3. We put a color(red)(1 ...

For the reaction KClO3 KCl+3/2O2 assign oxidation numbers to each element on each side of the equation. K in KCIO3= CI in KCIO3= O in KCIO3= K in KCI= CI in KCI= Which element is oxidized? CI, K, O Which element is reduced? CI, O, K

Sep 24, 2014 · 2KClO₃ → 2KCl + 3O₂ For one method, see How do you balance redox equations by oxidation number method? Your unbalanced equation is KClO₃ → KCl + O₂ Step 1. The oxidation numbers are: Left hand side: K = +1; O = -2; Cl = +5 Right hand side: K = +1; Cl = -1; O = 0 Step 2. The changes in oxidation number are: O: -2 → 0; Change = +2 Cl: +5 → -1; Change = -6 Step 3. Equalize the ...

Apr 18, 2018 · 9.0color(white)(l)"mol" Potassium chlorate "KClO"_3 decomposes to produce potassium chloride "KCl" and oxygen "O"_2.

Dec 8, 2015 · "2KClO"_3("s")" + heat"rarr"2KCl(s)" + "3O"_2("g")" "KClO"_3("s")" + heat"rarr"KCl(s)" + "O"_2("g")" Notice that the number of atoms of "K" and "Cl" are the same on both sides, but the numbers of "O" atoms are not. There are 3 "O" atoms on the the left side and 2 on the right. 3 and 2 are factors of 6, so add coefficients so that there are 6 "O" atoms on both sides. "2KClO"_3("s")" + heat"rarr ...

Feb 9, 2016 · After which, multiply the number of moles of potassium chlorate with its molar mass. This will give you an answer equal to 1039.125 grams of potassium perchlorate. The dimensional analysis involved is shown below: Mass of potassium perchlorate, g = 7.50 moles KCl x (2 mol KClO3)/(2 mol KCl) x (138.55 g KClO3)/(1 mol KClO3) = 1039.125 grams KClO3

Aug 10, 2017 · 10 more grams of "KClO"_3 can dissolve. To solve this, let's look at a solubility curve graph: The curve for "KClO"_3 is the brown line, and according to the 70 ""^"o""C" vertical line, a saturated solution of "KClO"_3 contains color(red)(30color(white)(l)"g" in 100 "g H"_2"O".

For the reaction KClO3 KCl+32O2 assign oxidation numbers to each element on each side of the equation. K in KClO3: K in KCl: Cl in KClO3: Cl in KCl: O in KClO3: O in O2: Which element is oxidized? Cl O K Which element is reduced? K O Convert 1444.0 mmHg into pa

Question: KClO3+MnO2---->KCl+O2+MnO2 1. Write the balanced chemical equation. 2.What is the purpose of MnO2? 3. If you started with 1Kg of KClO3 and 5Lbs MnO2 A. What mass of KCL would you have after the reaction has completed? B. …
