Does oxygen and hydrogen explode when ignited?
Oxygen has a tremendously greater attraction for electrons than hydrogen does, so when hydrogen donates an electron to oxygen, there is a substantial release of energy. This energy appears in the form of heat, so the gases (hydrogen, oxygen, and water vapor which is the product of the reaction) will be very hot. Hot gases expand rapidly, hence, they explode.
Who created hydrogen?
how made hydrogen how made hydrogen how made hydrogen how made hydrogen
What does h stand for in h20?
Hydrogen. The lightest element.
What is difference between hydrogen sulfide and hydrogen sulphide?
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
Is hydrogen poisonous?
Hydrogen is not poisonous.
What causes air to expand?
hydrogen and gases
Why does water expand instead of increaing?
due to hydrogen bond
Do stars expand in size?
Stars expand in size to become red giants, when they start running low on Hydrogen fuel.
What type of bonds cause water to expand when it freezes?
Hydrogen bonds
How do you lower the density of the hydrogen gas?
You can lower the density of hydrogen (or any) gas by heating it in a container where it is free to expand, like a balloon.
Does water freeze when it expands?
Yes. Water is one of the few substances on earth that does expand when frozen most other things expand when heated. The hydrogen bonds between the hydrogen and oxygen atoms straighten and the water molecule expands.
Can a star get larger?
Yes. Most stars will expand to many times their original size when they run out of hydrogen in their cores.
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
Which element in the core of a high mass star leads ultimately to a supernova explosion?
The Answer may be hydrogen. Hydrogen moves to the suns core as it starts to die, or explode. hydrogen is a very flammable gas. A star, like the sun is surrounded by heat. this heat will ignite the hydrogen gases as it moves to the core. This ignition of the hydrogen will cause the star to expand in size and increase in temperature.
When ice melts does it expand?
yes it does. one of the consequences of water due to hydrogen bonding.
What is the mass of 1 milliter of hydrogen atom without the electron?
1 milliliter of hyrdogen ions would not exist, as any number of hydrogen +1 ions would expand rapidly in a vaccum, or react with the environment if there was one.
When a star has exhausted its supply of hydrogen?
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity. Core contracts, temperatures incrase. This causes outer layers to expand and cool. This star is called a GIANT.
