Answer: Cell
Explanation: The cell is the most basic unit of life.
Answer:
In carbon containing compounds, carbon usually forms four bonds, nitrogen usually forms three bonds, oxygen usually forms two bonds, and hydrogen only forms one bond.
Explanation:
In organic compounds in which carbon is present, the number of bonds formed depend on the number of electrons available for each chemical element. In the case of Carbon, it is 4. Nitrogen is 3. Oxygen is 2. Hydrogen is 1. In other types of compounds, it is possible to see different types of bonds.
Answer:
V = 479.6 mL
Explanation:
assuming ideal gas:
∴ T = 25.2°C ≅ 298.2 K.........remains constant
∴ P1 = 637 torr = 0.8382 atm
∴ V1 = 536 mL = 0.536 L
∴ R = 0.082 atm.L/K.mol
⇒ n = (P1V1)/(RT) = ((0.8382 atm)*(0.536 L))/((0.082 atmL/Kmol)*(298.2K))
⇒ n = 0.0184 mol......remains constant
∴ P2 = 712 torr = 0.936842 atm
⇒ V2 = RTn/P2 = [(0.082atmL/Kmol)*(298.2K)*(0.0184mol)]/(0.936842atm)
⇒ V2 = 0.4796 L
Convection drives the earth's atmosphere and dictates the distribution of life in the world's oceans.
