B. a&b) Fe2(SO4)3 + 6 LiOH --> 3 Li2SO4 + 2 Fe(OH)3 (s), A chemical equation in which the formula for each substance is written without regard for whether it is an electrolyte or a nonelectrolyte, A chemical equation in which dissolved strong electrolytes are written as separate ions b) (5.0 M)(V1) = (0.10M)(250 mL) Equation for K3PO4 + H2O (Potassium phosphate + Water) Similarly, a compound consists of a number of ions or atoms. Ask a question for free Get a free answer to a quick problem. Expert's answer Balanced chemical reaction (dissociation): KPO (aq) 3K (aq) + PO (aq). Determine whether each cation is acidic or pH neutral. 2. What remains when the spectator ions are removed is called the net ionic equation, which represents the actual chemical change occurring between the ionic compounds: It is important to reiterate that the spectator ions are still present in solution, but they do not experience any net chemical change, so they are not written in a net ionic equation. solvent solute A substance that conducts electricity when dissolved in water is called a (n) ; whereas a substance that does not conduct electricity in aqueous solution is a (n) . Write the equation for the neutralization of lemon juice (citric acid) with baking soda (sodium hydrogen carbonate or sodium bicarbonate) that shows a proton transfer to form carbonic acid and a salt. M=mol/L c) 0.163 M e) 39.0 mg, Na2S (s) + Cd(NO3)2 (aq) --> CdS (s) + 2 NaNO3 (aq) (First show the reaction with H+ (aq) as a product and then with the hydronium ion.) c) 1.84 M 0.015 mol K2CO3/L x (1 mol CO3 2-/1 mol K2CO3) = 0.015 M CO3 2- 2 Al (s) 6 H+ --> 2 Al3+ (aq) + 3 H2 (g). = 5.0 mL (1) KBr(s) (2) NaNO_2(s) (3) Al(NO, Use the following salts to create a 0.100 M solution. d) Ag2SO4 8600 Rockville Pike, Bethesda, MD, 20894 USA. Answer: E. A sample of an iron ore is dissolved in acid, and the iron is converted to Fe2+. a) Al is normally 3+, so N = 3- Write the chemical equation that represents the dissociation of (NH4)2S. a) H2S (determinant of how acidic or basic a substance is) P.S, H+ (aq.) the Ag+(aq) and Cl(aq) ions become AgCl(s), but the Na+(aq) ions and the NO3(aq) ions stay as Na+(aq) ions and NO3(aq) ions. "Proton Donors" d) 7.42x 10^-5 M Write the net acid-base reaction that occurs when dissolved NaC2H3O2 reacts with water. Helmenstine, Todd. 0.015 M K2CO3 x (2 mol K+/1 mol K2CO3) = 0.03 M K+, Interconverting Molarity, Moles and Volume, Moles of x = (L soln) x (mol of x/L soln) Which solution(s) are the most electrically conductive? One brand of mineral water contains 1.55 ppm of dissolved nitrate. Latest answer posted December 07, 2018 at 12:04:01 PM.
