So, what’s the difference between premium and regular gas? Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Who has the best qualityRead More →
The six noble gases that occur naturally are helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). What does noble gases mean in the periodic table? The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable dueRead More →
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy. Are gasses low density?Read More →
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds. Why is Xe a nobleRead More →
The particles of a gas move about randomly at very high speeds because of large spaces and very less attractive forces between them. … Because of this continuous collision between the particles of the gas and the walls of the container, the gas particles exert pressure on the walls ofRead More →
“Insoluble” generally means that a substance does not dissolve in water. Some examples include: sand, fats, wood, metals, and plastic. When we put them in water and try to mix them, they will not dissolve. Is hydrogen gas insoluble in water? Hydrogen gas is highly insoluble in water. … TheRead More →
Noble gases are monoatomic because they have complete octet (apart from Helium, which has duet) , hence they are highly stable on their own and do not react with others to form compounds in standard temperature and pressure conditions. Why is argon monoatomic? Argon being a noble gas is ArRead More →
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable. Are noble gases low reactive?Read More →
All gases have weight (1 litre of air in a normal room weighs approximately 1 gram). Most gases encountered by students are colourless (e.g. air, water vapour and oxygen). Smoke, fog and smog are not coloured gases but rather small particles of carbon or water droplets suspended in the air.Read More →
It is also good to know that ideal gas law assumes that the gas molecules have negligible/no size. Keeping that in mind, Xe is the largest of the bunch, and therefore is expected to have the greatest deviation of the ideal gas when under high pressure or low temperature. WhyRead More →
