Charles’s law gives V₁/T₁ = V₂/T₂.
V₂ = 2×500÷200 = 5 L.

Kc contains product concentrations over reactant concentrations.
Each concentration is raised to its stoichiometric coefficient.

Charles’s law gives V₁/T₁ = V₂/T₂.
V₂ = 4×400÷320 = 5 L.

Charles’s law gives V₁/T₁ = V₂/T₂.
V₂ = 6×300÷360 = 5 L.

PV = nRT, so P = nRT/V.
Substitution gives approximately 100 kPa.

PV = nRT, so P = nRT/V.
Substitution gives approximately 99.9 kPa.

PV = nRT, so P = nRT/V.
Substitution gives approximately 100 kPa.

AIDS is the advanced stage of HIV infection.
Severe immune suppression permits opportunistic infections and cancers.

AIDS is the advanced stage of HIV infection.
Severe immune suppression permits opportunistic infections and cancers.

Reverse transcriptase copies viral RNA into DNA.
The viral DNA can then integrate into the host genome.

Retroviruses possess an RNA genome and use reverse transcriptase.
HIV is an important human retrovirus.
