The hydrocarbons that will undergo substitution reactions with chlorine would be those that are saturated.
What are saturated hydrocarbons?They are hydrocarbons that contain no double or triple carbon to carbon bonds.
Such hydrocarbons cannot undergo addition reactions unlike those that contain double or triple bonds.
Alternatively, saturated hydrocarbons are able to undergo substitution reactions with chlorine in the presence of light, with hydrogen being displaced in the process.

How many kilojoules of heat are produced when 34.0 g of Fe2O3 reacts with an excess of CO according to the following reaction? Fe2O3 + 3 CO 2 Fe + 3 CO2 ΔH = -26.3 kJ
The heat produced when iron oxide reacts with carbon monoxide is -23.47 kJ/mol.
What is the enthalpy of reaction?
The standard enthalpy of the reaction is given by the enthalpy of formation of the products and the reactants. The reactants and the products of the reaction are:
Fe₂O₃ (s) + 3CO (g) → 2Fe(s) + 3CO₂ (g)
We know,
The standard enthalpy of formation of iron oxide = −825.50 kJ/mol
The standard enthalpy of formation of carbon monoxide = −110.53 kJ/mol
The standard enthalpy of formation of carbon dioxide = −393.52 kJ/mol
The standard enthalpy of reaction is calculated as:
[tex]\rm \Delta H_{rxn}[/tex] = [2(0) + 3(−393.52)] - [1(-825.50) + 3(-110.53)]
= (0−1180.56+825.50+331.59)
= −23.47 kJ/mol
Therefore, −23.47 kJ/mol is produced.

which term best defines the feeding behavior of most gulls?
Answer:
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus
how many grams of sodium Phosphate is needed to prepare 5.0 L of a 2.6M solution ?
Molarity is the ratio of the moles and the volume. The mass of 2.6 M sodium phosphate solution is 2131.22 gms.
What is mass?
Mass is the product of the moles and the molar mass of the substance. It is given as,
Mass = Moles × Molar mass
The moles from molar concentration is used to calculate mass as:
Mass = Molarity × volume × molar mass
= 2.6 × 5.0 × 163.94
= 2131.22 gms
Therefore, 2131.22 gms is the mass of sodium phosphate.
