Answer:yes they have the same mass.
2,000 times as massive as an electron.
The nucleus
electrons make the greatest contribution to the chemical properties of the atom.

Answer:
Na2SO3 + H2O2 = Na2SO4 + H2O
Explanation:
Chemical reaction and equation.
Answer:
1.346 v
Explanation:
1) Fist of all we need to calculate the standard cell potential, one should look up the reduction potentials for the species envolved:
(oxidation) → E°=0.337 v
(reduction) → E°=1.679 v
(overall) +8H^{+}_{(aq)}→ E°=1.342 v
2) Nernst Equation
Knowing the standard potential, one calculates the nonstandard potential using the Nernst Equation:
Where 'R' is the molar gas constant, 'T' is the kelvin temperature, 'n' is the number of electrons involved in the reaction and 'F' is the faraday constant.
The problem gives the [red]=0.66M and [ox]=1.69M, just apply to the Nernst Equation to give
E=1.346
