Based upon the mass of baking soda (NaHCO3) and using an excess of HCl in this experiment, you will 1) determine the mass of CO2 produced (actual yield); 2) calculate a theoretical yield for CO2; and 3) calculate a percent yield for CO2.

Equation of reaction

NaHCO3 +  HCl  >  NaCl  +  H2O  +  CO2(g)

1)The mass(actual yield) of CO2 can be gotten by isolating it from other products and getting its mass.

Assume 1.0g of CO2 was gotten as a product of the experiment

2) For the theoretical yield

The mass of NaHCO3 was not stated, but for the purpose of this solution, I would assume 2g of NaHCO3 was used for the experiment. You can substitute any parameter by following the steps I follow

Number of mole of NaHCO3 = Mass of NaHCO3/ Molar Mass of NaHCO3

Number of mole of NaHCO3 = 2/84.01 = 0.0238 moles

1 mole of NaHCO3 yielded 1 mole of CO2

0.0238 moles of NaHCO3 will yield 0.0238 moles of CO2

Mass of CO2 = Number of moles * Molar Mass

Mass of CO2 = 0.0238 * 44 = 1.0472g

Theoretical yield of CO2 = 1.0472 grams

3) Percentage yield of CO2 = Actual yield/Theoretical yield *100%

Percentage yield of CO2 = 1.0/1.0472 *100

Percentage yield of CO2 = 95.49%

The correct order of events (with dates and notes following):

The Soviet Union’s spies gathered information about the US Manhattan projectThe United States created three bombs as a result of the Manhattan Project. The Soviet Union detonated its first atomic bomb.  The United States detonated the first thermonuclear or hydrogen bomb.

Details:

Soviet espionage concerning the Manhattan Project occurred all the way along the line during the project, from 1940-1945.The first bomb, called "Gadget," was detonated as a test model in July, 1945.  The "Little Boy" and "Fat Man" bombs were dropped on Hiroshima and Nagasaki in August, 1945.The Soviet Union tested its first atomic bomb in 1949.The US achieved development of a hydrogen bomb in 1952.
