4.95 is the number of molecules in 500m cube of Oxygen at room temperature and pressure
we have got data
pressure=1atm
temperature=298 k
volume=500 m^3
gas constant, R=8.31
now, by applying ideal gas equation
PV=nRT
1×500=n×8.31×298
n=2476.38/500
n=4.95
It is the lowest part of the material and has chemical elemental properties. Atoms do not independently exist; rather, they combine to form ions and molecules, which then combine to form the material that we can see, feel, and touch.
Molecules are made up of one or more atoms connected by covalent (chemical) connections. Atoms can be visualized as circles with a nucleus in the center (made up of protons and neutrons) and one or more concentric circles around it that indicate the "shells" or "levels" in which the electrons surrounding the atom's nucleus are located, as well as markings that identify the electron. each level

<span>oxidation, because oxygen is combining with the banana peel, and the peel is reacting with the air.</span>
AgNO3(ag) + NaBr(aq) ----> AgBr(s) + NaNO3(aq)
the ionic equation
Ag+(aq) + NO3-(aq) + Na +(aq) +Br-(aq) -----> AgBr(s) + Na+(aq) + NO3-(aq)
cancel the spectator ions in this case Na+ and No3-
the net ionic equation is therefore =
Ag+(aq) + Br-(aq) ----> AgBr (s)
