This is a synthesis reaction in which sodium and chlorine combine to form sodium chloride. It can also be called a combination reaction.
The sample with the greatest mass at STP would be the one with the highest molar mass, as 1 mole of any substance at STP occupies the same volume (22.4 L). Among the given options, the sample with Cl2 gas (molar mass = 70.9 g/mol) would have the greatest mass.
A. Of the choices listed, the helium atom is the smallest in both size and mass, and so its behavior is more "ideal." 1.He(g) Of the choices listed, the helium atom is the smallest in both size and mass, and so its behavior is more "ideal."
The equilibrium constant, K_eq, for the reaction 2HCl(g) ⇌ H2(g) + Cl2(g) is equal to the concentration of H2 and Cl2 divided by the concentration of HCl squared, as products are in the numerator and reactants in the denominator.
