mass of oxygen to ignite 20g of hydrogen in oxygen

Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it constitut..

Summary - Alcohols and Phenols are compounds containing -OH as the functional groups. In alcohols, the -OH group is attached to sp 3 hybridised carbon. In phenols, it is attached to sp 2 hybridised carbon of an aromatic ring. In ethers, oxygen atom is attached to two carbons ato..

Oxygen (or dioxygen) has the following physical properties. Oxygen is colorless, odorless and a tasteless diatomic gas under normal conditions. Oxygen is slightly heavier than air. Its density relative to air is 1.1053. Oxygen is sparingly soluble in..

A proton is actually a hydrogen atom, which has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is 1 a.m.u., the relative ..

Hydrogen atom (Z = 1) has no neutrons. Number of protons = 1Number of electrons = 1Number of neutrons = 0It has been reported that the hydrogen element has atoms with mass number 2 and 3 also i.e., Atoms of elements having the same atomic number with differe..

. While the mass of one atom of hydrogen is considered as 1 atomic mass unit, hydrogen gas in its natural state has 3 isotopes of atomic mass 1, 2 and 3 respectively. Thus average mass works out to be 1.008 a.m.u rather than 1 a...

The centre of mass is an imaginary point where one can assume the entire mass of the given system or object to be positioned. Consider a system consisting of two point masses m1 and m2, whose position vectors at a time t with reference to the origin ..

It is the mass of a body measured, when it is in translatory motion, by the application of external force other than gravity. where a 1 and a 2 are accelerations of bodies of masses m 1 and m 2 respectively. Inertial balance is used to measure inertial..

It is the most abundant isotope of hydrogen. Its nucleus has one proton and no neutron (mass number = 1). It is represented as H..
