The Volume Change Associated with a Chemical Reaction Is Often $\degree$

question 95

Multiple Choice

The volume change associated with a chemical reaction is often approximated as being directly proportional to the change in the number of moles of gas moles of gaseous products - moles of gaseous reactants) .The combustion of methanol at 25 $\degree$ C and 1 atm releases about 1453 kJ of heat.Which of the following correctly describes the relationship between $\Delta$ E and $\Delta$ H ? 2 CH₃ OH(l) + 3 O₂(g) $\rightarrow$ 2 CO₂(g) + 4 H₂O(l)

• A)(\(\Delta\)H \(\lt\) -1453 kJ, \(\Delta\)E =-1453 kJ)
• B)(\(\Delta\)H \(\gt\) -1453 kJ, \(\Delta\)E = -1453 kJ)
• C)(\(\Delta\)H = -1453 kJ, \(\Delta\)E \(\gt\)-1453 kJ)
• D)(\(\Delta\)H =-1453 kJ, \(\Delta\)E \(\lt\) -1453 kJ)
• E)(\(\Delta\)H= -1453 kJ, \(\Delta\)E = -1453 kJ)

Definitions:

Pathogens

Microorganisms that can cause disease in hosts, including bacteria, viruses, fungi, and parasites.

Elasticity

The ability of tissue or material to resume its normal shape after being stretched, compressed, or altered in any way.

Chronic Wounds

Wounds that fail to proceed through the normal stages of healing in an orderly and timely manner, often remaining open for an extended period.

Full-Thickness Wounds

Wounds that extend through the dermis to affect deeper tissues and potentially muscle or bone, requiring more complex healing processes.
