A. decrease the amount of weight until she can do ten reps B. increase the amount of weight until she can do three reps C. decrease the amount of weight until she can do five reps D. increase the amount of weight until she can do one rep Please select the best answer from the choices provided. The skeleton equation is: H 2 S + KMnO 4 + H 2 SO 4 → S+ MnSO 4 + K H SO 4 + H 2 O . It is a Redox reaction. (b) … Get more help from Chegg. Therefore: The oxidation state of "Fe" is +3, and The oxidation number is "III", so … Potassium is the major cation (positive ion) inside animal cells, while sodium is the major cation outside animal cells. "FeCl"_3 "Cl"^(-) is the anion here, and there are three. there are equal numbers of atoms on each side of the reaction arrow. What is the number of moles of electrons that pass through the cell and the average current (in amperes) that passes through the cell? What’s the oxidation number of k2so4 - 10529051 o to get the BEST workout? Carefully, insert coefficients, if necessary, to make the numbers of oxidized and reduced atoms equal on the two sides of each redox couples. Question: 4. Show transcribed image text. K2Cr2O7 + FeSO4 + H2SO4 = Cr2(SO4)3 + Fe2(SO4)3 + K2SO4 + H2O is a very common chemical reaction. We learn how to balance the chemical equation of this redox reaction. The reaction 2 AgNO3 (aq) + K2SO4 (aq) → 2 KNO3 (aq) + Ag2SO4 (s) is an example of a(an) ________ reaction. oxidation number of each chromium and write the following equation: 2x + 7(-2) = - t… x = + x. -inventory the number and types of atoms and adjust coefficients such that there are the smallest whole number coefficients. In potassium sulfate, K 2 SO 4, the oxidation numbers are: potassium +1 sulfur +6 and oxygen -2. Write down the transfer of electrons. The sum of the oxidation numbers in K 2 SO 4 (a compound) is zero. I dont really know what to do here, the part where i am stuck is when i have to write the numbers to the compounds. SO 4 2-: (+6) + 4(-2) = -2. The Oxidation Number Of S In K2SO4 Is A) +6 B) +4 C) +2 D) -1 E) None Of The Above. K2SO4 in the sulfur oxidation number is: +2 +4 +6 -2 -4. You do it in context by knowing the charges of other ligands or atoms bound to them. Here are some examples that span general chemistry to advanced inorganic chemistry. So all i know is: Left side: KMnO4: K=+1, Mn=+7, O4= -2*4=-8 H2O2: H2= +1*2=+2, O2=-1*2=-2 H2SO4: H2= +1*2=+2, O4 = -2*4=-8, S=+6 Right side: MnSO4: Mn=+2, S=+6, O4= -2*4=-8 O2= 0 K2SO4: K=+1*2=+2, S=+6, O4= -2*4=-8 H2O: H2=+1*2=+2, O=-2 Mn goes from +7 to +2 is … The Oxidation Number Of S In K2SO4 Is A) +6 B) +4 C) +2 D) -1 E) None Of The Above. The oxidation number of the sulfur atom in the SO 4 2-ion must be +6, for example, because the sum of the oxidation numbers of the atoms in this ion must equal -2. Step 2 (a) The oxidation number of various atoms involved in the reaction. K2Cr2O7 FeSO4 H2SO4 are reacts to give multiple products. 19. See the answer.
