Two soccer teams, the Bears and the Panthers, played games at the same time in two different locations. The Bears game was playe

d at sea level, where there is a normal amount of oxygen. Before their game, the players on the Bears ate a lunch of mostly starch. The Panthers game was played at very high altitude, where there is less oxygen. The players on the Panthers ate a lunch of starch and protein. Which team probably did better in their game?

First question

Pb(NO_3)_2 + KI \rightarrow PbI_2 + KNO_3

Balaneced:

Pb(NO_3)_2 + 2KI \rightarrow PbI_2 + 2KNO_3

Find how many moles potassium iodide it is in 345.0 grams

n_{KI} = \frac{345.0 \ g}{166.0 \ g/mol} = 2.078 \ mole

Find how many moles potassium nitrate there is for 2.078 moles KI

n_{KNO_3} = \frac{2}{2} \cdot n_{KI} = 2.078 \ mole

Find how many grams potassium nitrate there is in 2.078 moles KNO_3

m_{KNO_3} = 2.078 \ mol \cdot 101.1 \ g/mol = 210.1 \ g

Second question

yield \ \% = \frac{experimental}{theoretical} \cdot 100 = \frac{195.3 \ grams}{210.1 \ grams} \cdot 100 = 93.0 \ \%

In 4.0 years , 40.0 kilograms of elemnt a decays to 5.0 kilograms
alexira [117]
This problem is requiring us to find the half life of the element. We can solve this problem by using the equation as shown: A=Aoe^-(ln2/t)T where A is the final amount (5 kilogram), Ao is the initial amount (40.0 kilogram), t is the half-life (required) and lastly T time elapsed (4.0 years). Plug in the values in the equation and you should get 1.33 years as the half life.
