IT does not mention the observed yield

PLEASE HELP ME

Assume you perform the procedure outlined in the experiment “% Yield of Sodium Carbonate”. The reaction is as follows: NaHCO3(s) ® Na2CO3(s) + CO2(g) + H2O(g).

You weigh out 1.4895 g baking soda (NaHCO3), heat it, and are left with 1.0026 g of solid (Na2CO3). What is the total mass of gases that was actually produced in the experiment? (Hint: During the reaction, gases will be released to the air. Thus some mass “is lost to the air”) Note: The following questions are all based on this first question.

D)

0.4869 g

Based on the above two questions, calculate the total theoretical mass of gases that should have been produced.

How much CO2 gas should be produced from 1.4895 g NaHCO3? (These are theoretical yield)

The Answer is

A)

0.3901 g

How much H2O gas should be produced from 1.4895 g NaHCO3 ? (These are theoretical yield)

Th Answer is

D)

0.1596 g

How much gas altogether should be produced? (Theoretical yield)

A)

0.5497 g

B)

62 g

C)

44 g

D)

1.1994 g

Calculate your percent yield of gases using formula percent yield = (actual yield / theoretical yield) * 100% (This equation will be used often, please memorize it)

A)

29.1%

B)

88.58%

C)

0.08858%

D)

0.0291%

    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...

    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...

    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...
