the subscript g after H2O indicates that it is water vapour, a gas, which is what the subscript g stands for. If there was a subscript s after the H2O, it would mean that H2O is in a solid form as ice. If there was a subscript l it means that H2O is in the liquid form as water.
The subscript "g" in H2O indicates that the water molecule is in the gaseous state, meaning it exists as a gas.
its solid state :0)
The "l" subscript on H2O signifies that water is in its liquid state at room temperature and pressure.
Michael W. Swagel has written: 'The determination of the g[subscript J]([superscript 3]P[subscript 1]) value and g[subscript J]([superscript 1]P[subscript 1]) value of barium and the ratio A([superscript 1]P[subscript 1])/[[Greek letter mu subscript O]g[subscript J]([superscript 1]P[subscript 1]) ] of mercury-199' -- subject(s): Barium, Mercury, Spectra, Spectrum analysis
It means that it is in a liquid state as opposed to solid (ice) or gas (water vapour or steam)
The reaction between nitric oxide gas and hydrogen gas to form ammonia gas and water vapor is represented by the equation: 2 NO(g) + 4 H₂(g) -> 2 NH₃(g) + 2 H₂O(g) This is a synthesis reaction where the two reactants combine to form two different products.
eg. O2 (where the 2 is subscript) This shows that there are TWO INTRAMOLECULARLY-BONDED atoms, ie. two atoms joined together. Or, if you are referring to (g), (l), (s) and (aq) subscripts: (s) - solid (g) - gas (l) - liquid (aq) - aqueous, or dissolved in water
To determine the subscript of the empirical formula, you first need to calculate the molar mass of the compound using the given percentages. Then, divide the molar mass of the compound by the molar mass of each element (12.01 g/mol for C, 1.01 g/mol for H, and 16.00 g/mol for O). Finally, divide the resulting values by the smallest value obtained to get the simplest ratio of elements in the compound, which will give you the subscript of the empirical formula.
Keq = [H2O][CO] [H2][CO2]
ctrl = for subscript ctrl shift = for superscript
You can write a subscript (g) after the formula for the gas. For example, CO2(g).
(s) for solid, (l) for liquid, (g) for gas
