Fission fusion worksheet nuclear weapon

1 answer:

6 0

Nuclear fusion and fission are two atomic processes that release tremendous amounts of energy. The primary difference is that in fission, heavier atoms are broken down into smaller ones, while smaller atoms join together to form heavier ones in fusion.

The process of fission is the one that is used in atomic bombs and nuclear power plants. Fusion requires a large amount of energy to be started and is the energy production process for stars.

Calculate the percentage by mass of the indicated element in the following compounds. Hydrogen in ascorbic acid, HC6H7O6, also k

Scorpion4ik [409]

Answer: The mass percent of hydrogen in ascorbic acid is 4.5 %

Explanation:

In $C_6H_8O_6$ , there are 6 carbon atoms, 8 hydrogen atoms and 6 oxygen atoms.

To calculate the mass percent of element in a given compound, we use the formula:

$\text{Mass percent of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Molar mass of ascorbic acid}}\times 100$

Mass of hydrogen = $8\times 1g/mol=8g$

Molar Mass of ascorbic acid = $6\times 12g/mol+8\times 1g/mol+6\times 16g/mol=176g$

Putting values in above equation, we get:

$\text{Mass percent of hydrogen}=\frac{8g}{176}\times 100=4.5\%$

Hence, the mass percent of of hydrogen in ascorbic acid is 4.5 %.

The molar mass of carbon dioxide is 44.0 g/mol. How many moles of CO2 are present in a 58.4 gram sample of CO2

inessss [21]

Answer:

1.33 moles CO2

Explanation:

The number you are converting is 58.4 g CO2, so you start with this value. The conversion factor is 44.0 g/mol CO2. In order to cross out the grams, the grams must go on the bottom of the conversion factor.

1 mol CO2
58.4 g CO2 x -------------------------- = 1.33 moles CO2
44.0 grams

The answer has three sig figs.
