In the periodic table, elements of the same group are characterized by having the same similar properties.
So, first we will check the elements that lie within the same group as <span>beryllium and then we will attempt to choose the elements with atomic mass higher than 130.
So, elements in the same group as </span>beryllium are: magnesium, calcium, strontium, barium and radium.
Among these elements, we will find that:
radium has atomic mass of 226 amu
barium has atomic mass of 137.327 amu
Based on this, the two elements would be barium and radium.

Answer:
Value of for the given redox reaction is
Explanation:
Redox reaction with states of species:
Reaction quotient for this redox reaction:
Species inside third braket represent concentration in molarity, P represent pressure in atm and concentration of is taken as 1 due to the fact that
is a pure liquid.
So,
Plug in all the given values in the equation of :
