Technetium has a half-life of six hours. If you obtain 100g of a pure technetium sample, after 18 hours how much of the pure sub

IgorLugansk [536]

Answer:

After 18 hours, the amount of pure technetium that will be remaining is 12.5 grams

Explanation:

To solve the question, we note that the equation for half life is as follows;

$N(t) = N_0 (\frac{1}{2} )^{\frac{t}{t_{1/2}}$

Where:

N(t) = Quantity of the remaining substance = Required quantity

N₀ = Initial radioactive substance quantity = 100 g

t = Time duration = 18 hours

${t_{1/2}$ = Half life of the radioactive substance = 6 hours

Therefore, plugging in the values, we have;

$N(t) = 100 (\frac{1}{2} )^{\frac{18}{6}} = 100 (\frac{1}{2} )^{3} = \frac{100 }{8} = 12.5 \ grams$

Therefore, after 18 hours, the amount of pure technetium that will be remaining = 12.5 grams.

370 cm3 of water at 80°C is mixed with 120 cm3 of water at 4°C. Calculate the final equilibrium temperature, assuming no heat is

NikAS [45]

Answer : The final temperature of the mixture is $61.4^oC$

Explanation :

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

$q_1=-q_2$

$m_1\times c_1\times (T_f-T_1)=-m_2\times c_2\times (T_f-T_2)$

And as we know that,

Mass = Density × Volume

Thus, the formula becomes,

$(\rho_1\times V_1)\times c_1\times (T_f-T_1)=-(\rho_2\times V_2)\times c_2\times (T_f-T_2)$

where,

$c_1$ = $c_2$ = specific heat of water = same

$m_1$ = $m_2$ = mass of water = same

$\rho_1$ = $\rho_2$ = density of water = 1.0 g/mL

$V_1$ = volume of water at $80.0^oC$ = $370cm^3=370mL$

$V_2$ = volume of water at $4^oC$ = $120cm^3=120mL$

$T_f$ = final temperature of mixture = ?

$T_1$ = initial temperature of water = $80.0^oC$

$T_2$ = initial temperature of water = $4^oC$

Now put all the given values in the above formula, we get:

$(\rho_1\times V_1)\times (T_f-T_1)=-(\rho_2\times V_2)\times (T_f-T_2)$

$(1.0g/mL\times 370mL)\times (T_f-80.0)^oC=-(1.0g/mL\times 120mL)\times (T_f-4)^oC$

$T_f=61.4^oC$

Therefore, the final temperature of the mixture is $61.4^oC$

A sample of coal has the following analysis (wt %). Moisture 1.1%, Fixed Carbon 74%, Volatile Matter 17.9%, Carbon 63.7%, Hydrog

pogonyaev

Answer:

Coal is a traditionally used source of energy, there are main four types of ranks for coal. Here the rank of a coal means to a natural process called Coalification, which takes place during a plant is buried and changes to a harder, and denser material and become even more rich in carbon contents.

Anthracite is know to have the highest ranked coal, it contains highest percent of fixed carbon and lowest percent of volatile material.
