Indicate/write all species including mobile ions, liquids, and solids present in product mixture. Write the Total ionic and net ionic equation. Molecular Equation: NH3(aq) + HC2H302(aq) → NH4C2H302(aq) Reaction mixture is Acetic Acid - HC2H302 Product mixture is Ammonium Acetate -

The dilution equation, rearranged to solve for ?1 is   ?1=?2?2?1 where ?1 and ?1 are the initial concentration and volume, respectively, and ?2 and ?2 represent the final concentration and volume, respectively. A student needs to prepare 50.0 mL of 1.10 M aqueous H2O2 solution from 4.8 M H2O2 stock solution. Set up an equation to solve for the volume of stock solution needed by plugging the given values into the equation.

What is the mass percent of calcium if 0.429 g of calcium oxalate forms in a 125-g sample of milk when excess aqueous sodium oxalate is added? Na,C2O4(aq) + Ca²*(aq) → CaC2O4(s) + 2Na*(aq) a. 0.107% b. 0.202% с. 0.343% d. 1.10% е. 1.37% 25. Identify all the spectator ions in the following reaction. KSO4(aq) + 2MNSO4(aq) + 5FE2(SO4)3(aq)

A reaction is carried out by mixing together a solution of HF and a solution of NaOH. HF (aq) + NaOн (аq) —> н,О (1) Assume the purple particles below each represent 1 mole of particles. Construct the balanced net ionic equation by dragging the purple components into the gray boxes. Drag each unreacted spectator ion along with its balancing coefficient into the blue box that represents the aqueous solution. Remember when you identify spectator ions to look carefully at what changes chemically! + NaF (aq)

The reaction of hypothetical elements: A, B, C, D, and E, follows the molecular equation:   AB2(aq) + CDE(aq) -> AE(s) + CB(aq) + DB(aq)   Assuming that all aqueous compounds would fully dissociate, indicate the element/s that would form spectator ions in the subsequent total ionic equation.

This question has multiple parts. Work all the parts to get the most points. Complete and balance the equation for the following acid-base reaction. Name the reactants. Assume complete neutralization. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (ag) or (s). If a box is not needed, leave it blanl H3 AsO4 (aq) + NaOH(aq) → |H3 AsO4 (aq) + NaOH(aq)
