What else can I help you with?
Infer what state hydrogen and helium would be in at room temperature?
Both the elements exist in gaseous states at room temperatures.
What is the state of matter at room temperature of hydrogen as a solid?
If it were a solid at room temperature, then that would be the state of matter. However, hydrogen is NOT solid at room temperature. It is a gas and that would be the state of matter.
Would an hydrogen balloon float better than a helium one?
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
Is helium dense or less dense than water?
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
Where would Helium 1s be relative the hydrogen 1s?
There is one thing that is relative to both helium and hydrogen. Both of these are a type of chemical.
Is helium safe to fill balloons with?
Yes. I would go with helium if you can get it. Hydrogen can explode.
Is the sun made up of mostly hydrogen?
Essentially yes; the sun's energy comes from nuclear fusion with hydrogen being converted to helium.
Why must a star convert helium after it has converted all of its hydrogen to helium?
As a star exhausts its hydrogen fuel and increases in temperature and pressure, it needs to start fusing helium to produce energy and maintain equilibrium against the inward force of gravity. This process is necessary to sustain the star's energy output and prevent collapse.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
An equal mass of helium would contain fewer atoms compared to hydrogen, as each helium atom is four times heavier than a hydrogen atom. This is because the atomic mass of a helium atom is roughly four times that of a hydrogen atom.
Which gas would be more suitable for the Hindenburg?
Helium was more suitable but not available in Germany before the war.
How is the formula for hydrogen different from the formula for helium?
I am unsure what you mean by the formula for Hydrogen and Helium because both are an element, not a compound and you would generally not have a formula for an element. However, I can tell you that the difference between the formula for Hydrogen gas and Helium gas if; Hydrogen gas: H2 H-H Helium gas: He Hope this helps
What is the really cold gas?
In its coldest state, matter would be a solid - with no movement of any of the atoms. Realistically if the pressure was low enough it might remain a gas even at 0 K - but that's strictly theoretical
