A sample of radioactive waste has a half-live of 40 years and an activity level of 4 curies. After how many years will the activ

Westkost [7]

After 160 years, the activity level of the sample will be 0.5 curies.

Half life of any radioactive waste is the half decay of that product.

The formula is $\dfrac{\lambda }{\lambda_1} = 2^\dfrac{a}{b}$

Where, λ is 4 cruies

λ1 is 0.5 cruies

b = 40 years

Putting the values in the equation

$\dfrac{4}{0.5} = 2^\dfrac{a}{40}\\\\\\\dfrac{a}{40} = 4\\ = 160 years$

Thus, the correct option is 160 years.

How many kilojoules of heat are released when 32.0 g of NaOH are dissolved in water? (The molar heat of solution of NaOH is –445

Katen [24]

The energy release when dissolving 1 mol of NaOH in water is 445.1 kJ
the mass of NaOH to be dissolved is 32.0 g
The number of NaOH moles in 32.0 g - 32.0 g / 40 g/mol = 0.8 mol
the energy released whilst dissolving 1 mol of NaOH - 445.1 kJ
when dissolving 0.8 mol - the energy released is 445.1 kJ/mol x 0.8 mol
therefore heat released is - 356.08 kJ
answer is -356.08 kJ
