Hydrogen is a clean alternative to methane, also known as natural gas. It's the most abundant chemical element, estimated to contribute 75% of the mass of the universe.Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course, humans. But while...
What is the density of hydrogen gas at25∘Celsius and 1 atm? Density of Gases: As with any kind of matter, we determine the density of gases by dividing its mass,m, by its volume,V, such thatρ=mV. We can assume the ideality of the gas for our computation in order t...
A 0.100g sample of carbon-hydrogen-oxygen compound is combusted in a stream of pure oxygen and produces 0.220g CO2 and 0.239g H2O. What is the mass of hydrogen in the sample? If 36 grams of water is split into hydrogen and oxygen ...
process is a major contributor to climate change, which is why an increasing number of countries are switching to ‘green’ hydrogen produced using renewable energy. TheUS Department of Energysays hydrogen has “potential for near-zero greenhouse gas emissions” when produced usin...
liquid and gas. The illustration implies that the molecules are composed of a diatomicelementin which each molecule consists of two atoms of the same element, such as hydrogen (H2), nitrogen (N2), oxygen (O2) or chlorine (Cl2). However, transitioning between states is common to most matter...

The density of a substance is the mass present in a unit volume of its sample. Density varies with the phase of the substance sample, in which gases are much less dense than solids and liquids. The density of a gas is also very sensitive to the temperature and pressure conditions...

However, if Earth were a little closer to the Sun, its oceans would evaporate; if it were farther from the Sun, the oceans would freeze solid. [#highlight12]Because liquid water was present, self-replicating molecules of carbon, hydrogen, and oxygen developed life early in Earth’s history...
