The use of force, usually in the absence of any drugs, to assist in the performance of medical procedure, such as intubating the trachea.
When reacted with butane, oxygen (O2) is needed to form carbon dioxide (CO2) and water (H2O) in a combustion reaction. The balanced chemical equation for this reaction is: 2 C4H10 + 13 O2 -> 8 CO2 + 10 H2O
No, butane, pentane, and hexane are not members of the same homologous series. They are all alkanes, which form a homologous series characterized by the general formula CₙH₂ₙ₊₂. Each successive member differs by a CH₂ group, making them part of the same series. Therefore, butane (C₄H₁₀), pentane (C₅H₁₂), and hexane (C₆H₁₄) are indeed members of the same homologous series of alkanes.
