β⁻ emission is an emission of an electron from the parent atom while converting a neutron into a proton.<span> Hence, the formed daughter nucleus has the same number of mass but the atomic number is higher by 1 and number of neutrons is lower by one than the parent atom.</span><span>

After a β⁻<span> emission of ¹⁰⁶Ru, the formed daughter nucleus should have 106 as mass number but (44 + 1) = 45 </span>as the atomic number.  </span><span>

<span>Hence the daughter nucleus is </span>Rh<span> (</span>Rhodium<span>) which has </span>45<span> protons (atomic number).</span></span>

A sample of 0.500 mol of hydrogen has a pressure of 3.00 atm and a
sergey [27]

Answer:

The volume is 10,92 L

Explanation:

We use the formula PV=nRT:

V= (nRT)/P

V= (0,500 mol x 0,082 l atm/K mol x 799 K)/3,00 atm

<em>V= 10,91966667 L</em>
