(See, Q:Pb(NO,),(aq) + 2 KCI(aq) This matches the number of hydrogens = 2 and number of chlorines = 2 on the RHS. A student tries to determine experimentally the molar mass of aspirin (HAsp). #Zn^(2+)# + 2e- Zn - 0.76V Mg(s) + 2 H+(aq) + 2 Cl-(aq) ---------------- Mg+2(aq) + 2 (b) What is its solubility in grams per 100 g of water? orbital diagram of carbon . What is, A:Given: First, write the two salts in aqueous ion form: Mg(s)+Zn^(2+)(aq) +2Cl^-1 (aq) rarr Zn(s)+Mg^(2+)(aq) +2Cl^-1 (aq) Since no change occurs in the chloride ion, these are "spectators" and can be . It was commonly used as a dye in the first half of the nineteenth century. If an electrode reaction has dissolved oxygen as a reactant, is the electrode and anode or a cathode? Second, we write the states and break the soluble ionic compounds into their ions (these are the strong electrolytes with an (aq) after them). We place the number 2 ahead of the HCl. 1 answer; aP Chemistry; asked by Nichole; 836 views; The enthalpy of formation of C2H5OH is . 5.2Mg+2CuSO4=Cu2+2MgSO4 First, we balance the molecular equation. 12. Q:(a) What is the molar solubility of BaSO4? Identify the precipitate, or lack thereof, for the, A:In any chemical reaction when the products obtained are insoluble in nature they form precipitate., Q:To simulate the pH of blood, which is 7.4, an undergraduate researcher in a biology lab produced a. Besides being an acid, it is a reducing agent. 2. break the aqueous species into, Q:titrated 18.00 mL of HCl solution with 58.6 mL of 0.145 M NaOH solution to the endpoint. Second, we write the states and break the soluble ionic compounds into their ions (these are the strong electrolytes with an (aq) after them). Since no change occurs in the chloride ion, these are "spectators" and can be omitted: #Mg(s)+Zn^(2+)(aq) rarr Zn(s)+Mg^(2+)(aq) #.
