What kind of reaction is hydrogen and oxygen?
When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. An example of a simple chemical reaction is the breaking down of hydrogen peroxide molecules, each of which consists of two hydrogen atoms bonded to two oxygen atoms (H2O2).
Does hydrogen and oxygen explode?
Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud.
How does hydrogen bond with oxygen?
Strong linkages—called covalent bonds—hold together the hydrogen (white) and oxygen (red) atoms of individual H2O molecules. Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other.
How does oxygen bond with hydrogen?
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Opposites attract, so this lopsided charge difference allows bonds to form between the hydrogen and oxygen atoms of adjacent H2O molecules.
Why does H2 not react with O2?
(a) H2andO2 do not react at room temperature because the activation energy is high for that reaction which is not provided at room temperature.
Why is hydrogen attracted to oxygen?
Hydrogen atoms are attracted to other atoms such as oxygen atoms, because the electrons are pulled closer to the oxygen atom, due to its greater attraction for electrons. As a result the oxygen atom has a slightly negative partial charge and the hydrogen atoms have a slightly positive partial charge.
Is Earth the only planet where fire can burn?
Earth is the only known planet where fire can burn. Everywhere else: Not enough oxygen. Oxygen supply influences the color of the flame. A low-oxygen fire contains lots of uncombusted fuel particles and will give off a yellow glow.
Can you combust water?
No, your refreshing glass of water won’t spontaneously combust. Water is made up of two elements, hydrogen and oxygen. Hydrogen is flammable, but oxygen is not. You can’t burn pure water, which is why we use it to put out fires instead of starting them.
Can you combine hydrogen and oxygen for water?
Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. The trouble with adding energy into the equation is that a large-scale chemical reaction of flammable hydrogen and oxygen (which is what keeps a fire burning) is likely to result in a rather large explosion.
