Answer: A photon of energy was released.

Explanation: The energy of the orbitals keep on increasing as the size of the orbitals keep on increasing or the value of n keeps on increasing.

The electrons absorb energy when they are irradiated or put at high temperatures and move to higher energy states. The electrons then get back to their ground state by releasing energy in the form of radiations. Thus when an electron move from n = 2 to shell n = 1, the absorbed energy is given off in form of photons of energy.

Energy is released or absorbed in the form of discrete packets of energy called as photons.

Answer:

В.  No, because the mass of the reactants is less than the mass of the products.

Explanation:

Chemical equation:

NaBr + Cl₂      →      2NaCl + Br₂

The given equation is not balanced because number of moles of sodium and bromine atoms are less on reactant side while more on the product side.

There are one mole of sodium and one mole of bromine atom on left side of equation while on right side there are 2 moles of bromine and 2 moles of sodium atom are present. The number of moles of chlorine atoms are balanced.

Balanced chemical equation:

2NaBr + Cl₂      →      2NaCl + Br₂

Now equation is balanced. Number of moles of sodium , chlorine and bromine atoms are equal on both side.
