Answer : The density of a sample of chlorine gas is, 12.59 g/L
Explanation :
To calculate the density of chlorine gas we are using ideal gas equation.
where,
P = pressure of chlorine gas = 4.5 atm
V = volume of chlorine gas = 12.6 L
n = number of moles of chlorine gas
w = mass of chlorine gas
R = gas constant = 0.0821 L.atm/mol.K
T = temperature of chlorine gas = 
M = molar mass of chlorine gas = 71 g/mol
Now put all the given values in the above formula, we get:
Therefore, the density of a sample of chlorine gas is, 12.59 g/L
Explanation:
Ionic bonds are bonds formed as a result of the electrostatic attraction between two species.
- This bond type is an interatomic bond.
- It forms when two specie with a large electronegative difference between them combines.
- This is usually a metal and a non-metal.
- The metal loses its valence electrons and becomes positively charged.
- The non-metal gains the electron and becomes negatively charged.
- An electrostatic attraction between the two specie leads to the formation of an ionic bond.
- They are solids with a high melting point.
- They are soluble in polar solvents.

Answer: "The reactants are higher in energy than the products"
Explanation:
The exothermic reactions are characterized by the release of heat to the surroundings. The reactants lose heat that is delivered to the surroundings which implies that the products will be lower in energy than the reactants.
The hills that you can see in a reaction energy diagram are not related with the final change of energy. The hills are an indication of the activation energy needed to start the reaction, but they do not measure the change of energy from the products to the reactants.
The enthalpy that is a state variable that identifies the content of heat. Then the change of enthalpy for the exothermic reactions is negative, meaning that the energy of the products is lower than the energy of the reactants.
