They are fused into helium and create energy. But it takes 4 hydrogen atoms to make 1 atom of helium. The Hydrogen is first converted to Deuterium (heavy hydrogen), and the two deuterium atoms fuse to make the Helium atom. This process releases a lot of energy, not the least because of the neutrons released. Lol

What is a unique property of water Describe the property and explain the chemical or physical reason that causes water to have the property?
Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.
How is lithium formed in stars?
Lithium is formed through the fusion of a hydrogen and a helium ion. This will only occur at very high temperatures and pressures.
How are hydrogen bonds important in your body?
Hydrogen bonds are important to the body for several reasons. For one thing, they cause DNA to retain its double helix structure. Additionally, they contribute to the folding of proteins, which is necessary for proper protein function.
A student asserts that silicon and germanium become good insulators at very low temperatures and good conductors at very high temperatures. Do you agree?
silicon and germanium have 4 valence electrons...they will be bound by covalent bonds at very low temperature..hence there will be no delocalized electrons to conduct electricity..therefore at low temperature these two elements behave like insulators....at high temperature,the energy will be sufficient to break the covalent bond and thus electrons become delocalized....therefore at high temp they behave like conductors
Are there hydrogen bonds between molecules in steam?
Water is a polar substance. In liquid water, this gives rise to hydrogen bonds between molecules, making it structurally more compact. However when water is heated up to steam, those hydrogen bonds break up and the molecules cannot be maintained globally as aggregates. The forces in play in steam are of collisional type and the polarity of the molecules does result in short-range attractive forces yielding negative second virial coefficients but in no way the molecules arrange themselves to conform to a hydrogen-bonded structure. The probability of simultaneous collision between several molecules though rare in steam may become important at high pressures below the critical point, but should not be confused with the structuration between neighbouring molecules in liquid water where hydrogen bonding takes place due to the closeness between water molecules. What is sure is that there is no hydrogen bonds above the critical point of steam. In steam hydrogen bonding is just not taking place for the molecules are too distant from each other. Collisional binary encounter does not generate hydrogen bonding!!!
In DNA molecules Which bonds are disrupted at high temperatures?
hydrogen bonds
Waters high specific heat is mainly a consequence of the?
absorbtion and release of heat when hydrogen bonds break and form
Do hydrogen bonds form more quickly in higher temperatures?
All bond will break at high temperature; in another word, bond will not form more quickly in higher temperature but instead it form at low temperature.
Why does H2O have high such values for its specific heat and boling point?
H2O has high values for its specific heat and boiling point because it is made up of hydrogen bonds. Hydrogen bonds are the strongest type of intermolecular forces. Hydrogen bonds occur whenever hydrogen bonds with fluorine, oxygen, or nitrogen. Since they are the strongest type of bonds, it takes much more energy to break apart the molecules, which is what needs to happen for something to boil.
Does water have a low vapor pressure?
High heat of vaporization. It requires a great deal of energy to break the H bonds in water.
What causes of high melting point of water?
High polarity and hydrogen bonds.
Liquids with hydrogen bonds tend to have viscosities?
High Viscosities
What stops water from becoming too hot or boiling?
Water has a high specific heat (resistance to temperature change) because of its hydrogen bonds. Before raising its temperature, the heat has to go into disrupting the hydrogen bonds so they can break, and then the molecules can move faster to become a gas.
What The high surface tension of water explains why water?
Water molecules can make hydrogen bonds with other water molecules. Hydrogen bonds are the strongest type of intermolecular forces. This explains the high surface tension of water.
What is one type of molecule that forms hydrogen bonds with each other?
The most well known molecule that hydrogen bonds is water. This is why water has such a high boiling point and high surface tension.
What happens to hydrogen atoms at a very high temperatures?
They ionize (into plasma).
Will liquid hydrogen and liquid oxygen react when blended?
No. Hydrogen and oxygen will only react at high temperatures.
