Question 1

For an explosion in an open vessel, one would expect
◦ ΔH to be positive and ΔE to be less than ΔH.
◦ ΔH to be positive and ΔE to be greater than ΔH.
◦ ΔH to be negative and ΔE to be greater than ΔH.
◦ ΔH to be negative and ΔE to be less than ΔH.

Question 2

When 20.00 moles of H2(g) reacts with 10.00 mol of O2(g) to form 20.00 mol of H2O(l) at 25°C and a constant pressure of 1.00 atm. If 1366 kJ of heat are released during this reaction, and PΔV is equal to -74.00 kJ, then
◦ ΔH° = -1366 kJ and ΔE° = -1440 kJ.
◦ ΔH° = +1366 kJ and ΔE° = +1440 kJ.
◦ ΔH° = -1366 kJ and ΔE° = -1292 kJ.
◦ ΔH° = +1366 kJ and ΔE° = +1292 kJ.

Autoimmune diseases occur when the immune system destroys its own healthy tissues. When this occurs, white blood cells cannot distinguish between pathogens and normal cells.

Did you know?

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.

Did you know?

There are immediate benefits of chiropractic adjustments that are visible via magnetic resonance imaging (MRI). It shows that spinal manipulation therapy is effective in decreasing pain and increasing the gaps between the vertebrae, reducing pressure that leads to pain.

Did you know?

Computer programs are available that crosscheck a new drug's possible trade name with all other trade names currently available. These programs detect dangerous similarities between names and alert the manufacturer of the drug.

Did you know?

When intravenous medications are involved in adverse drug events, their harmful effects may occur more rapidly, and be more severe than errors with oral medications. This is due to the direct administration into the bloodstream.
