Hydrogen sulfide occupies 278.2 cm3 at 26oC and standard pressure What is the mass of the hydrogen sulfide?
To find the mass of hydrogen sulfide, we need to use the ideal gas law equation. The molar volume of an ideal gas at STP (standard pressure and temperature) is 22.4 L/mol. First, convert the given volume to liters (0.2782 L), then calculate the number of moles using the ideal gas law. Finally, multiply the number of moles by the molar mass of hydrogen sulfide (34.08 g/mol) to find the mass.
What is the systematic name for H2S?
Hydrogen Sulfide. It is present as a gas at room temperature, but is an acid.
What is the density of H2S gas at STP?
The density of hydrogen sulfide is 1.363 g/cm3.
The decomposition reaction of hydrogen sulfide?
The decomposition reaction of hydrogen sulfide (H2S) is: 2 H2S -> 2 H2 + S2. This reaction occurs when hydrogen sulfide is heated to a high temperature, breaking down into hydrogen gas and sulfur.
Why is hydrogen sulphide a gas at room temp?
Hydrogen sulfide is a gas at room temperature because it has a low boiling point of -60.3°C. This means that at room temperature (usually around 20-25°C), hydrogen sulfide remains in its gaseous state.
Is hydrogen sulfide a solid?
This largely depends on the pressure and temperature that the Hydrogen Sulfide is at. However, at room temperature hydrogen sulfide is a gas. At normal pressure it condenses to liquid at -60 °C (boiling point) and solidifies at -80 °C (melting point).

Is the density of water more than the density of hydrogen sulfide?
It is substantially more when water is a liquid (it weighs 1000 g/cubic dm) as hydrogen sulfide (H2S) is a gas weighing 1.363 g/cubic dm. However, a molecule of hydrogen sulfide weighs more than a molecule of water (H2O).
When Hydrogen sulfide is boiling is it a chemical or physical change?
Boiling hydrogen sulfide is a physical change, as it is a reversible process where the substance changes from a liquid to a gas due to the absorption of thermal energy. The chemical composition of hydrogen sulfide remains the same during boiling.
Which of the following statements is NOT true about hydrogen sulfide?
hydrogen sulfide is not hazardous
Why is hydrogen sulphide a gas at room temp?
Hydrogen sulfide is a gas at room temperature because it has a low boiling point of -60.3°C. This means that at room temperature (usually around 20-25°C), hydrogen sulfide remains in its gaseous state.
What is the metal element in hydrogen sulfide?
Hydrogen sulfide is H2S and has no metals. Both hydrogen and sulphur are non metals.
What is the density at STP of hydrogen sulfide gas (H2S)in grams per liter?
The density of hydrogen sulfide gas (H2S) at standard temperature and pressure (STP) is approximately 1.363 grams per liter. This value can be derived from the molar mass of H2S, which is about 34.08 g/mol, and the fact that one mole of gas occupies 22.4 liters at STP. Thus, the density is calculated as the molar mass divided by the molar volume.
What is hydrogen sulfide symbol?
The chemical formula for hydrogen sulfide is H2S.
