What happens when hydrogen and nitrogen are combined in the presence of heat?
They react to form ammonia
What are the 6 most abundant elements in the biosphere?
Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
The key elements for a fire?
Fuel, Oxygen and Heat Fuel, Oxygen and Heat Fuel, Oxygen and Heat
Which is the most heat resistant Oxygen mercury iron or nitrogen?
oxygen
What happens when you combine 2 hydrogen atoms with one oxygen to make water?
The combination of the atoms releases heat energy.
Is air a mixture of hydrogen and oxygen gases?
No, air is a mixture of gases that primarily consists of nitrogen (about 78%) and oxygen (about 21%), along with smaller amounts of other gases like argon, carbon dioxide, and water vapor. Hydrogen is present in very small traces in the atmosphere.
What happens hydrogen and carbon during combustion and what is formed as a result?
During combustion, hydrogen and carbon react with oxygen to form water and carbon dioxide. The hydrogen combines with oxygen to form water vapor (H2O), while carbon combines with oxygen to form carbon dioxide (CO2).
Is kevlar a hydrogen bond?
No, Kevlar is not a hydrogen bond. Kevlar is a synthetic fiber made of a strong, heat-resistant polymer matrix. Hydrogen bonds are weak electrostatic interactions between hydrogen atoms and electronegative atoms like oxygen or nitrogen.
What happens when chlorine and hydrogen peroxide react with each other?
When chlorine and hydrogen peroxide react, they form hydrochloric acid and oxygen gas. This reaction is exothermic, meaning it releases heat energy.
What happens when hydrogen peroxide and vinegar react together?
When hydrogen peroxide and vinegar react together, they produce oxygen gas and water as byproducts. This reaction is exothermic, meaning it releases heat energy.
What physical bond is easily broken by water and heat?
Hydrogen bonds are easily broken by water and heat. These bonds are weak forces that form between the slightly positive hydrogen atom of one molecule and the slightly negative atom of another molecule, such as oxygen or nitrogen. When exposed to water and heat, hydrogen bonds can be disrupted, causing molecules to separate.
What does heat and copper nitrate produce?
copper oxide, nitrogen and oxygen
