Cobalt-60 is produced by neutron activation. in this process, one neutron is absorbed by the nucleus of the parent isotope. what
kkurt [141]

The parent isotope is cobalt-59 (see the picture below).

The mass number is 59 and atomic number is 27 of the parent isotope.

Neutron activation is the process in which atomic nucleus capture free neutron or neutrons.

Cobalt-60  is produced in nuclear reactors in process of neutron activation from parent isotope cobalt-59 (see the picture below).

Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.

Cobalt-59 and cobalt-60 are the isotopes of chemical element cobalt.

Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).

A chemical reaction occurring in a cylinder equipped with a moveable piston produces 0.641 mol of a gaseous product. If the cyli
snow_tiger [21]

<u>Answer:</u> The final volume of the reaction is 4.69 L

<u>Explanation:</u>

The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.

The equation used to calculate number of moles is given by:

\frac{V_1}{n_1}=\frac{V_2}{n_2}

where,

V_1\text{ and }n_1 are the initial volume and number of moles

V_2\text{ and }n_2 are the final volume and number of moles

We are given:

V_1=2.05L\\n_1=0.280mol\\V_2=?L\\n_2=0.641mol

Putting values in above equation, we get:

\frac{2.05}{0.280}=\frac{V_2}{0.641}\\\\V_2=\frac{2.05\times 0.641}{0.280}=4.69L

Hence, the final volume of the reaction is 4.69 L
