... addition reaction; the hydrogen molecule is split, one of its atoms is added to each carbon atom that is initially double bonded, and an alkene becomes an alkane.

... known as hydrogenation.
Hydrogen gas is produced when sodium is added to water. This reaction is highly exothermic and can result in the sodium igniting.
If hydrogen is added to hydrogen bromine, no chemical reaction occurs because both substances are already in their elemental forms. Hydrogen is H2 and hydrogen bromine is HBr, so the two compounds do not have any atoms available to bond and react with each other.
When acid is added to a metal, hydrogen gas is given off as a product of the reaction. This is because the acid reacts with the metal to form a salt and hydrogen gas. The general reaction is metal + acid → salt + hydrogen gas.
Well, darling, when magnesium is added to a solution of sodium hydrogen sulfate, a chemical reaction occurs. The magnesium will kick sodium to the curb and form magnesium sulfate, while hydrogen gas gets released into the wild blue yonder. It's like a soap opera in a test tube, drama and chemistry all in one!
h2
Yes, hydrogen is a product of this reaction.
To avoid a violent reaction.
Hydrogen gas is produced when sodium is added to water. This reaction is highly exothermic and can result in the sodium igniting.
MnO2 is added as a catalyst in the decomposition of hydrogen peroxide (H2O2) reaction to increase the rate of the reaction. It provides a surface for the reaction to occur on, which lowers the activation energy needed for the decomposition of hydrogen peroxide into water and oxygen gas.
The reaction represents a single replacement reaction where the metal displaces the hydrogen in the acid to form a salt and releases hydrogen gas as a byproduct.
If hydrogen is added to hydrogen bromine, no chemical reaction occurs because both substances are already in their elemental forms. Hydrogen is H2 and hydrogen bromine is HBr, so the two compounds do not have any atoms available to bond and react with each other.
This is a fusion process, the nuclear reaction that powers our Sun. Hydrogen and hydrogen isotopes come together to make helium
Hydrogen ions and a pair of electrons are added to NAD+ to reduce it to NADH. This reduction reaction is important in cellular respiration for the generation of ATP.
An example of a reduction reaction where hydrogen is not added to the reduced compound is the reduction of iron(III) to iron(II) by vitamin C. In this reaction, vitamin C acts as a reducing agent by donating electrons to iron(III) without the addition of hydrogen.
When hydrogen gas is added to iodine, a chemical reaction occurs that forms hydrogen iodide (HI) gas. The reaction is exothermic, meaning it releases heat energy. This reaction is represented by the chemical equation: H2 + I2 -> 2HI.
If a gas is produced and it isn't a state change (such as steam bubbles forming), the reaction is a chemical change because the molecular makeup of either the water or the drain cleaner has changed and the hydrogen has been liberated.
When acid is added to a metal, hydrogen gas is given off as a product of the reaction. This is because the acid reacts with the metal to form a salt and hydrogen gas. The general reaction is metal + acid → salt + hydrogen gas.
