Methane is a hydrocarbon which when burns in air (combustion) produces carbon dioxide and water. The equation for the reaction;
CH4 +2O2 = CO2 +2H2O
When one mole of methane combusts 2 moles of water are formed
Therefore; when 22 moles of methane combusts 44 moles of water are formed (22 ×2)
Answer:
True rod cell are best in the dark or dim light.
Answer:
c is not a true statement
The effusion rate of H2 molecules is 4.342 times that of an unknown gas. Determine the molar mass of the unknown gas. You can write the formula for Graham's law of diffusion or effusion of gases as: rate 1 / rate 2 = √ (mass 2 / mass 1) , where: rate 1 and rate 2 - Rates of effusion or diffusion of Gas 1 and 2, respectively, measured moles per unit time
<h3>What is
H2 molecules?</h3>
The chemical element hydrogen is represented by the letter H and atomic number 1. The lightest element is hydrogen. Under normal circumstances, hydrogen is a gas made up of diatomic molecules with the formula H2. It is non-toxic, tasteless, colorless, odorless, and extremely flammable. In the cosmos, hydrogen is the most prevalent chemical, making up around 75% of all ordinary matter. [note 1] Plasma hydrogen makes up the majority of stars like the Sun. On Earth, hydrogen mostly takes the form of molecules like water and organic substances. Each atom of hydrogen's most prevalent isotope, 1H, has one proton, one electron, and no neutrons.
