If 765 mL of a gas at 2.78 atm, has the volume Change to 2.47 L , What is the pressure of the

vampirchik [111]

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new pressure

$P_2 = \frac{P_1V_1}{V_2} \\$

From the question

2.47 L = 2470 mL

We have

$P_2 = \frac{765 \times 2.78}{2470} = \frac{2142}{2470} \\ = 0.867206...$

We have the final answer as

Hope this helps you

Artyom0805 [142]

Answer:

The daughter nuclide is selenium; 76:34 Se

Explanation:

The complete question is as follows;

is desired to determine the concentration of arsenic in a lake sediment sample by means of neutron activation analysis. The nuclide 75:33 As captures a neutron to form 76:33 As, which in turn undergoes beta decay. The daughter nuclide produces the characteristic gamma rays used for the analysis. What is the daughter nuclide?

solution:
