How many milliliters of vinegar would you need to react with an excess of baking soda (NaHCO3) in order to generate 10.0 L of carbon dioxide gas at 1.05 atm and a temperature of 25.0°C? 7. Shown below is the aqueous reaction of KNOX, HCl, and SnCl2. 2 KNO2 (aq) + 6 HCl(aq) + 2 SnCl2 (aq) → 2 SnCla (aq) + N20 (g) + 3 H20 (1) + 2 KCl (aq)...

When H2CO3 forms as a product in the reaction with acetic acid (CH3COOH) in vinegar and HCO3 in baking soda, bubbles are formed. Those bubbles are from H2CO3 reacting (being removed from the solution) to generate water and CO2. Why does this removal of H2CO3 (product) shift the reaction Rate fwd < Raterev, so the reaction will shift to make more reactants To B Rate fwd > Raterev, so the reaction will shift to make more reactants o C Rate...

5, Vinegar should contain more than 4% acetic acid (CHCOOH, molar mass 60.0 g mor) 25.0 mL of vinegar are diluted to 100.0 mL and 10.0 mL samples of this solution are titrated against 0.100 mol L-NaOH solution. An average of 18.1 mL NaOH are required to neutralize the vinegar. You will need to calculate the concentration of the diluted solution and hence the percentage concentration of acetic acid in the original vinegar via the following questions: CH COOH(aq)...

If you are to prepare a 1.000 L of a 0.100 M buffer at pH 5.00 using the CH3COOH/ Na+CH3COO- buffer system (pKa 4.76a), answer the following questions: What is the molar ratio of the base to acid at pH 5.0? The concentration of the buffer (0.100 M in this example) refers to the sum of the weak acid and its conjugate base. Given this information, what is the concentration of the weak acid and its conjugate base at pH...
