When C₂H₅Cl(g)is Burned in Oxygen,chlorine Gas Is Produced in Addition

question 11

Multiple Choice

When C₂H₅Cl(g) is burned in oxygen,chlorine gas is produced in addition to carbon dioxide and water vapor.5145 kJ of heat are released for every four moles of C₂H₅Cl(g) burned.Which of the following correctly represents the thermochemical equation?

• A)4 C₂H₅Cl(g) + 5145 kJ + 13 O₂(g) → 2 Cl₂(g) + 8 CO₂(g) + 10 H₂O(g)
• B)4 C₂H₅Cl(g) + 13 O₂(g) + 5145 kJ → 2 Cl₂(g) + 8 CO₂(g) + 10 H₂O(g)
• C)4 C₂H₅Cl(g) + 13 O₂(g) → (5145 kJ) → 2 Cl₂(g) + 8 CO₂(g) + 10 H₂O(g)
• D)4 C₂H₅Cl(g) + 13 O₂(g) → 2 Cl₂(g) + 8 CO₂(g) + 10 H₂O(g) ?0?H = +5145 kJ
• E)4 C₂H₅Cl(g) + 13 O₂(g) → 2 Cl₂(g) + 8 CO₂(g) + 10 H₂O(g) ?0?H = -5145 kJ

Definitions:

Cap-And-Trade

Cap-and-trade is an environmental policy tool designed to reduce pollution by setting a limit (cap) on emissions and allowing businesses to buy, sell, or trade permits for emissions under this cap.

Emission Allowances

Emission allowances are permits or credits that allow the holder to emit a certain amount of pollutants over a set period.

Aggregate Emissions

The total amount of emissions (such as CO2, methane) released into the atmosphere by a specific entity, region, or activity, contributing to environmental impacts like climate change.

Sustainability Initiatives

Practices and strategies companies implement to manage and improve the environmental, social, and economic impacts of their operations.
