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).

xenn [34]
Given:

Sulfur dioxide and dihydrogen sulfide system

Vapor Pressure of water, H2O = 23 torr

P_SO2 = P_H2S

Temperature of the system = 298 K

Assume: Total pressure of the system is 1 atm = 760 torr

If partial pressure of SO2 is equal to the concentration of H2S, then,

760 = 0.5*PSO2 + 0.5PH2S
760 = PSO2

Amiraneli [1.4K]

Answer:

% yield =  82.5%

Explanation:

HgO + 2Cl₂ →  HgCl₂ +  Cl₂O

Our reactants are:

  • HgO and Cl₂

Our products are:

  • HgCl₂ +  Cl₂O

We do not have information about moles of reactants, but we do know the theoretical yield and the grams of product, in this case Cl₂O, we have produced.

Percent yield = (Yield produced / Theoretical yield) . 100

Theoretical yield is the mass of product which is produced by sufficent reactant. We replace data:

% yield = (0.71 g/0.86g) . 100 = 82.5%

WARRIOR [948]

Answer:

Specific heat capacity formula

Explanation:

The heat capacity gives the exact heat energy at which a given mass of a substance is heated from one temperature to another.

This formula can help determine how much heat is gained or lost during the reaction and is given by:

Q = mcΔT

where:

Q = heat energy in Joules or Calories

m - mass of the substance (g)

c = Specific heat capacity (J/kg°C)

ΔT = change in temperature = (final temp - initial temp) (°C)

I hope this was helpful.
