The reaction described is the formation of hydrogen chloride (HCl) from hydrogen gas (H2) and chlorine gas (Cl2). The negative enthalpy change of -184.6 kJ/mol indicates that the reaction is exothermic, meaning it releases heat. This energy release occurs as the bonds in the products (HCl) are formed, which are stronger than those in the reactants. Overall, this reaction highlights the energy dynamics involved in the synthesis of HCl from its elemental gases.
What else can I help you with?
What is keq for the reaction 2hclg h2g cl2g?
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.
2Nas Cl2g 2NaCls what is described in this equation?
This equation represents the reaction between sodium (Na) and chlorine (Cl2) gas to form sodium chloride (NaCl), which is commonly known as table salt. The reaction is a combination reaction where two reactants combine to form a single product.
Which 1.0 liter sample has the greatest mass at STP a CH4g b CL2g c CO2g d H2g?
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.
Under the same conditions of temperature and pressure which of the following gases would behave most like an ideal gas 1 Heg 2 NH3g 3 Cl2g 4 CO2g?
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."
