The current condition in the troposhere is (C) The Atmosphere
Deuterium has one proton and one neutron, 12H, while tritium has one proton and two neutrons, 13H.
animals, grass, and decomposers
D. mixture in which its components retain their identity
In a heterogeneous mixture, multiple substances are mixed, but they don't chemically react and they remain chemically the same.
Standard Temperature and Pressure (STP) are 273.15 K (Kelvin) and 101.3 KPa (kilopascals).
You can substitute 1 ATM (atmosphere) for the kilopascal measurement. It is discouraged to use 0°C for the temp equivalent since negative temperature numbers can't be used in gas equations..
