Why do water exist in liquid form and hydrogen sulphide exist in gaseous form?
Wiki User
∙ 11y ago
Oxygen (O) is more electronegative than sulfur (S). This means that H2O more polar than H2S.
This means that the forces of attraction between H2O molecules is grater than that in H2S molecules, making it harder to separate them from one another to turn it into a gas.

∙ 12y agothis is because h2 and o2, non polar molecules have only london forces actng upon them....and this london force is the weakest out of all three intermolecular forces whereas h20 has 2 hydrogen bonds present (stronger IMF) since h2o has stronger attrction to each other they will be closer, so its natural that it would be liquid in room temperatature

∙ 12y agoAlthough hydrogen sulphide has a greater molecular mass than water, water is a liquid at room temperature while carbon dioxide is a gas because of the strong intermolecular forces that hold water.
Wiki User
∙ 10y agoThe presence of hydrogen bonding in water, results in more molecules per unit volume. Hence H2O is liquid. No such hydrogen bonding is seen in H2S.
Wiki User
∙ 14y agoThis is because in H20 there is a hydrogen bond whereas in H2S the hydrogen is attracted by very weak van der waals forces

∙ 11y agoThat's correct, unless you've got an abnormally hot or cold room.
If you're asking WHY, it's because of strong hydrogen bonding in the case of water.

∙ 10y agoH2O have strong Hydrogen bonds.H2S have dipole-dipole bonds,weaker than H bonds.

Which is the only planet where the same substance can exist in gaseous and liquid and solid form?
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
Is the escape velocity of hydrogen at mars more than it's gravity or in other words can hydrogen in gaseous state exist on the planet mars?
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
Could NH4 be a gas?
NH4 is an ion. It does not exist under normal conditions. It may exist in combined state as Ammonium Chloride NH4Cl (which is a sublimates and exists only in solid and gaseous state), Ammonium Nitrate NH4NO3, Ammonium Sulphate (NH4)2SO4 which may exist in gaseous state at high temperatures. In case you are talking about Ammonia which is NH3, then yes,it is a gas under normal conditions but becomes a liquid on bubbling through water. (Ammonia solution of varying concentrations), much like Hydrogen Chloride, which on bubbling through water, forms, Hydrochloric acid in varying concentrations.
What is the matter state of water in the atmosphere?
Gaseous
Why does ionization take place in gaseous atoms?
Because in gaseous state all the atoms are comparable. In natural state some atoms (Elements) exist in solid state some in liquid and some in gaseous state.
Which is the only planet where the same substance can exist in gaseous and liquid and solid form?
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
Do all substances exist in a solid liquid or gaseous state?
Yes
Can and does francium exist in other forms?
Francium can be solid, liquid or gaseous.
Elements and substances can exist in these forms of matter?
Solid, liquid, gaseous and plasma.
What is the gaseous form of a substance which exist as a liquid at room temperature known as?
water is the substance
Can ice and boiling water exist at same temperature?
Yes. In fact, there is a specific combination of pressure and temperature where the solid, liquid, and gaseous phases can co-exist. Do some reading on "triple point".Yes.

What is the chemical difference between the gaseous and liquid state of the same substance?
Any chemical difference exist.
Infer what state hydrogen and helium would be in at room temperature?
Both the elements exist in gaseous states at room temperatures.
Nitrogen is a gas?
Yes, nitrogen exists in a gaseous form (N2) at at temperatures above its boiling point. It can also exist as a liquid at 77 K.
Why hydrogen chloride is a liquid while hydrogen chloride is a gas?
At the standard temperature and pressure, hydrogen chloride exists as a gas. It does not exist in liquid state, but in aqueous medium along with water as a solvent.
In what three states does water exist?
Water exists in liquid, (water); solid, (ice); and gaseous (steam) form.
What if the hydrogen is not a gas but something else?
Hydrogen can exist as a solid, a liquid, a gas, or a plasma, as well as many other states.
