Answer:
it will have 1 valence electron as its in the first group in the periodic table.
It will lose electrons as its easier.
The charge will be 1+ as it lost 1 .
The sum of all energies involved in breaking and or forming chemical bonds within the reactants side of the reaction is equal to the sum of all energies involved in the formation and rearranging of atoms within the product side of the chemical reaction.
The total energies of reactants = the total energies of products.
B) The frequency of the emitted light is directly proportional to the energy given off by the electrons.
Answer:
p = 1.5 atm
Explanation:
pV = nRT
p = nRT/V = [1.8 mol×(0.082 atm L/mol K)×247.8 K]/24.5 L
p = 1.5 atm
