Select the correct answer below: Select the correct answer below: none of the above. A) 0.276 and 0.828 This would also make the reactions look coherent since you are already denoting liquid state of aggregation this way. molar mass, Which of the following shows the correct stoichiometric ratio of Fe to Fe2O3? reactants NaBr+Cl2NaCl+Br2 d) The oxidation state of copper in copper sulfate is 0. e) 81.0%, X = C17N19NO3 Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Answer (1 of 3): HCl + H2O H3O^+ + Cl^- Note that in water, the free proton, H^+, does not exist but rather the hydronium ion, H3O^+ E) 100.0 mL of 0.500 M solution of HCl, What are the respective concentrations (M) of Fe3+ and I- afforded by dissolving 0.200 mol FeI3 in water and diluting to 725 mL? Cl2(g)ClO2(aq) 0.00504 mol H2SO4 x (2 mol NaOH/1 mol H2SO4) = 0.0101 mol NaOH Then the resulting reaction is H2 (aq) + 2 OH (aq) 2 H2O (). We therefore write the state symbol (s) after the compound that precipitates out of solution.If you are unsure if a compound is soluble when writing net ionic equations you should consult a solubility table for the compound._________________Important SkillsFinding Ionic Charge for Elements: https://youtu.be/M22YQ1hHhEYMemorizing Polyatomic Ions: https://youtu.be/vepxhM_bZqkDetermining Solubility: https://www.youtube.com/watch?v=5vZE9K9VaJIMore PracticeIntroduction to Net Ionic Equations: https://youtu.be/PXRH_IrN11YNet Ionic Equations Practice: https://youtu.be/hDsaJ2xI59w_________________General Steps:1. So for a reaction you might see an equation like equation (4). Viewed from a more active perspective, sodium functions as a reducing agent (reductant), since it provides electrons to (or reduces) chlorine. b) 7.43x10^-2 M . Mg(s) + Co2+ (aq) + SO4- (aq) --> Mg2+ (aq) + SO4- (Aq) + Co(s) front of the body_________________________, A homogeneous mixture of two or more substances, The dissolving medium of a solution; it is normally the component of a solution present in the greater amount, A substance dissolved in a solvent to form a solution; this is normally the component present in the smaller amount, A solute that produces ions in solution; an Electrolytic solution conducts an electric current, A substance that not ionize in water and consequently gives a nonconducting solution. (Be sure to specify states such as (aq) or (s). density 0.10 mol/L = moles According to the following reaction, if 69g of KClO3 decomposes, how many grams of oxygen will form: $$\ce{Ba^{2+}(aq) + 2Cl-(aq) + 2Na^{+}(aq) + SO4^{2-}(aq) <=> BaSO4(s) + 2Na^{+}(aq) + 2Cl-(aq)}\tag{3}$$. E) 1.75 , An aliquot (28.7 mL) of a KOH solution required 31.3 mL of 0.118 M HCl for neutralization. M=mol/L Second, we write the states and break the soluble ionic compounds into their ions (these are the strong electrolytes with an (aq) after them). If this solution were mixed with the one pictured above for HY, what species would be present in a diagram that represents the combined solutions after any possible reaction? Which of the following compounds is water soluble? Substances that are on the same side of an equation are separated by plus signs, indicating that they are both reactants or products, but that they are distinct, separate substances. B) 0.00155 Such as using $\ce{ ->[CH3OH]}$ to indicate that the reaction is happening in methanol. Zn+2HClZnCl2+H2 D) 2Al (s) + 6HBr (aq) 2AlBr3 (aq) + 3H2 (g) It contributes H+ to the net ionic equations. BaCl 2 + H 2 SO 4 = BaSO 4 + 2 HCl See Steps to Balance BaCl2 + H2SO4 = BaSO4 + HCl Solubility Equation a) P2O5 C) 1 part sample and 99 parts diluent C) 16400 Few exceptions; a) like O2 2-, each atom has a 1- oxidation number 1) Here is the complete ionic equation: 2K+(aq) + 2Al3+(aq) + 8OH-(aq) + 2H+(aq) + SO42-(aq) ---> 2Al(OH)3(s) + 2K+(aq) + SO42-(aq) + 2H2O() Note that the sulfuric acid is treated as fully dissociated. 0.800 mol of Ca3 ( PO4 ) 2 is soluble Ba^2+ + 2 Cl- - BaSO4...
