What is the word equation for the reaction that takes place when hydrogen burns in the air?

When hydrogen burns in air, it combines with atmospheric oxygen to form water. Since hydrogen and oxygen are undergoing a chemical change to become chemically bonded together producing H2O the change is chemical in nature.

What happens when you put potassium chloride into water?
The potassium reacts with the water to form potassium hydroxide and hydrogen gas. The reaction is very exothermic, and the hydrogen explodes during the reaction. THIS IS A VERY DANGEROUS REACTION! DO NOT ATTEMPT IT ON YOUR OWN!
Define an irreversible reaction?
An irreversible reaction is one in which the entire amount of a reactant or all of them are converted into products. They proceed only in the forward direction and an arrow pointing to the products is placed between reactants and products in the reaction equation. A chemical reaction becomes irreversible when one of the products leaves the homogeneous system where the reaction takes place. e.g. suppose A and B are the reactants, and C and D are the products. The reaction takes place in liquid phase. If one of the products precipitates (appears as an insoluble solid), or is a liquid that is not miscible with the reactant liquid phase, or is a gas that comes out of solution, then we have an irreversible reaction. Reversible reaction A + B ↔ C + D Irreversible reaction A + B → C + D↓ (D precipitates out of solution) A + B → C + D↑ (D bubbles out of solution)
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
If you add a piece of hydrogen peroxide tiny gas bubbles will form. However if you crush the piece of potato first more gas bubbles will form. Explain these observations?
The crushed piece has a greater surface area, and so the reaction takes place easier and faster.
What is the difference between an exothermic and endothermic reaction?
Exothermic (hyperthermic) reaction: a chemical reaction that releases energy,*Endothermic (hypothermic) reaction: a chemical reaction that absorbs energy.** Energy = heat, light, etc.The direction of Heat transfer:Exothermic reactions transfer heat energy to the environment.Endothermic reactions transfer heat energy from the environment .
What is equation for the reaction that takes place when magnesiam burns in aiur?
Reaction that takes place when magnesium burns in air= Magnesium + Oxygen = Magnesium Oxide (magnesia)
What is the reaction taking place as the hydrogen burns?
Water is formed when hydrogen gas burns (reacts) with oxygen (from air) 2 H2(g) + O2(g) --> 2H2O(l)
What is the reaction type when sodium is placed into water?
When sodium is mixed with water, a chemical reaction takes place and new compounds are formed, namely sodium hydroxide and hydrogen gas. Sodium hydroxide is highly corrosive and hydrogen gas is extremely flammable. The chemical equation for such a reaction is as follows: Na + H2O -> NaOH + H
When a candle burns in air which chemical reaction takes place?
combustion
What equation represents a reaction taking place in these stars?
There are many sorts of reactions that take place in stars, in the sun for instance the main nuclear chain reaction isP-P ( Proton-Proton ), in general the hydrogen consumed and turns into helium and by the way it produces a lot of energy.
What is the reaction equation between NH3 and HNO3?
The parts of a chemical equation always follow after the arrow are products and parts of a chemical equation always before the arrow are reactants . the reaction equation between NH3 and HNO3 is as follows .Balanced equation:HNO3 + NH3 = NH4NO3.The reaction type is syntheis reaction for the above equation and the reaction taking place .
Equation for benzene plus KMnO4?

What type of chemical reaction takes place when ammonia and hydrogen chloride gases are mixed and write a chemical equation of this?
NH3(g) + HCl(g) ==> NH4Cl(s). This type of reaction is called "synthesis". The two gases react to form a solid ammonium chloride salt.
