Is hydrogen sulfide a solid at standard room temperature and pressure?
No: hydrogen sulfide is a gas at standard room temperature and pressure
What is the concentration of hydrochloric acid?
Generally this concentration is 36.5 %. However cocentrations up to just over 40% are possible but require special pressure and cool temperature conditions because the vapor pressure of the hydrogen chloride (which is dissolved into water to make hydrochloric acid) is high enough to cause evaporation of the hydrogen chloride out of the solution which then reduces the concentration unless you have the pressure and temperature conditions.
What is the phase of hydrogen in room temperature?
The element hydrogen is in the gas phase at standard temperature and pressure.
What is hydrogen' s state of matter?
Hydrogen is a gas at standard temperature and pressure.
Which conditions of pressure and temperature would give the most accurate value of Mr?
Its high temperature and low pressure
Is hydrogen a electrical conuctor?
Hydrogen is not an efficient conductor of electricity under normal conditions, but can be made to conduct well at a low temperature under very high pressure.
Is hydrogen sulfide a solid at standard room temperature and pressure?
No: hydrogen sulfide is a gas at standard room temperature and pressure
What is the luster of hydrogen?
The element hydrogen does have a metallic form, which exists under conditions of both low temperature and high pressure. Under more usual conditions hydrogen is a gas and as such, has no luster. As a metal it has a metallic luster much like other metals.
Does a gram of hydrogen or a gram of oxygen have the greater volume at the same temperature and pressure?
They would have the same volume, as long as they are in the same conditions.

What is the state of hydrogen at room temperature?
Hydrogen is a gas at room temperature and standard pressure.
Why volumes of gases are converted into STP conditions and then compares?
Since volumes of gases change with temperature and pressure, a standard value of temperature and pressuure is chosen to which gas volumes are referred. Hence volumes of gases are converted into S.T.P. conditions and then compared easily.
Are hydrogen and helium gases?
They can be depending on the temperature and pressure. They can also be liquids and solids. At room temperature and pressure they are gases.
What is the partial pressure of hydrogen in air?
I think at sealevel and standard conditions the partial pressure of hydrogen is nearly zero (~0 Pa).
What is the colour of hydrogen bromide?
Hydrogen bromide is a colorless gas at standard temperature and pressure.
