2. Suppose a titration needed 27.15 mL of 0.2497M HCI solution to completely react 25.00mL Ba(OH)2 solution of unknown concentration. Identify and balance the chemical equation involved, then calculate the concentration of the Ba(OH)2 solution. 3 The heat change involved in the formation of 1.00 mol CO2 from its elements is 393 7k U/mo

Sodium hydrogen carbonate  NaHCO3 , also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid  HCl , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved  NaHCO3  neutralizes excess  HCl  through this reaction: HCl (aq)  +   NaHCO3 (aq)  →   NaCl (aq)  +   H2O (l)  +   CO2 (g)The  CO2  gas produced is what makes you burp after drinking the solution.   Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be  150.mL  of a  0.053  M  HCl  solution. What mass of  NaHCO3  would she need to ingest to neutralize this much  HCl  ? Be sure your answer has the correct number of significant digits.

If 20.0 g of LiOH is added to 0.750 L of 1.00 M Cd(NO₃)₂, how many grams of precipitate will be formed in the following precipitation reaction?    a) Write a balanced equation. Identify a precipitate. Include states of matter.  b) Determine how much precipitate would form if all reactant 1 ( LiOH) would be used up.  c) Determine how much precipitate would form if all reactant 2 ( Cd(NO3 )2 would be used up.  d) State Limiting reactant , and theoretical yield ( in grams) of the precipitate that would form from the given amounts.

Gold(III)hydroxide is used for electroplating gold onto other metals. It can be made by the following reaction (note the equation is unbalanced) KAuCl4(aq) + NaɔCO3(aq) + 3H,O(1) - Au(OH);(aq) + NaCl(aq) + KCI(aq) + CO2(g) To prepare a fresh supply of Au(OH), a chemist at an electroplating plant has mixed 20.00g of KAUC1, with 25.00g of Na CO3 (both dissolved im excess water) a. How many grams of NaCO: will b'required to react with KAUCI4? (only 3 decimal places) g of NanCO b. what is the maximum number of grams of Au(OH); than can be formed?

Sodium hydrogen carbonate (NaHCO,), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) + NaHCO3(aq) → NaCl(aq) + H,O(1) + CO,(9) The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 150. mL of a 0.049 M HCl solution. What mass of NaHCO, would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.

A solution is prepared by pipetting 25.0 mL of 0.350 M CuCl2 into a 100.0 mL volumetric flask, diluting to the calibration mark on the flask with water and quantitatively mixing the contents of the flask. What is the molar concentration of Cl- in the solution?
