What substance do you get when you burn hydrogen?
When hydrogen is burned in the presence of oxygen, it produces water as a byproduct. The chemical equation is 2H2 + O2 -> 2H2O.
What ion causes a substance to be acid?
The presence of hydrogen ions (H+) in a substance causes it to be acidic. In an aqueous solution, hydrogen ions are responsible for the characteristic sour taste and ability to react with bases.
What can weaken hydrogen bonds?
High temperature, polar solvents, and changes in pH can weaken hydrogen bonds by disrupting the electrostatic interactions between hydrogen and electronegative atoms. Additionally, the presence of other molecules that can compete for hydrogen bonding partners can also weaken hydrogen bonds.
In which substance can hydrogen peroxide decompose?
Hydrogen peroxide can decompose in the presence of certain substances, such as metals like iron or copper, as well as enzymes like catalase found in living organisms.
What is the gas produced when any metal reacts with acids?
Hydrogen gas is produced when any metal reacts with acids. This is a common reaction that is often used to test for the presence of metal in a substance.
How does the presence of hydrogen bonds affect the heat of fusion of a substance?

What substance yields no toxic compounds but only water and heat when it burns?
Hydrogen (H2) is an example of a substance that yields only water and heat when it burns. When hydrogen burns in the presence of oxygen, it combines to form water (H2O) as the only byproduct, making it a clean and efficient fuel source.
What are the type of intermolecular forces present in hydrogen iodide?
The intermolecular forces present in hydrogen iodide (HI) are dipole-dipole interactions and London dispersion forces. In HI, the hydrogen is partially positive while the iodine is partially negative, leading to dipole-dipole interactions. Additionally, the nonpolar nature of the HI molecule allows for the presence of London dispersion forces.
What is the flashing point of hydrogen peroxide?
The flash point of hydrogen peroxide is around 186 degrees Celsius (367 degrees Fahrenheit). This is the temperature at which the vapors from the substance can ignite momentarily in the presence of a flame.
How does the presence of hydrogen affect magnetic properties in materials?
The presence of hydrogen can affect the magnetic properties of materials by either enhancing or reducing their magnetic behavior. In some cases, hydrogen can weaken the magnetic properties of a material by disrupting the alignment of magnetic moments. However, in other cases, hydrogen can enhance the magnetic properties by promoting the formation of magnetic clusters or increasing the magnetic interactions between atoms.
State a test for the presence of hydrogen?
The burning splint test is used to test for the presence of hydrogen. The symbol for hydrogen is H.
Will a oxygen gas mixed with hydrogen gas produce substance?
If there is a source of activation energy, or in the presence of an active catalyst, these elements will react to produce water.
