PART ONE: 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...

4.2 Behavior of Gases Students will perform a simple reaction between NaHCO,+CH,COOH, or commonly known as baking soda and vinegar. In the pre-lab, students determine the moles of CO, by using the ideal gas law, PV=ORT where: P= Pressure (atm) V=Volume (lters...) n = moles (mol) T = Temperature (kelvin) R-Gas constant (atm:Imol:K) Students used STP, standard temperature and pressure, to determine their temperatures and pressure for this experiment. At STP, T = 273 K, and P 1 atm. Solve...

1. Moles of Reactant to Mass of Reactant: Identify the
iodide ions and ozone in the balanced chemical equation. Use mole
ratio, then convert to grams.
A method used by the EPA for determining the ozone concentration
in the air is to pass an air sample through a bubbler containing
iodide ions. The iodide ions remove the ozone according to the
following reaction:
O3(g) + 2 I-(aq) +
H2O(l) → O2(g) +
I2(aq) + 2 OH-(aq)
How many grams of ozone...

You will be observing a reaction in this lab. As with most reactions, this reaction occurs by the breaking of some bonds in the reactants and the formation of new bonds in the products. During the reaction, the gas that is produced will fizz away. After the reaction is complete, one of the products can be removed. Then you will determine the mass of the other product this will be your actual (or experimental) yield. You will compare this value...
