In junior high school, I learned chemical equations that generate water

Acid-base neutralization to produce water.

Ba+ and So4-, Ag+ and Cl-, Ca+ and CO3- form white precipitates.

Cu+ and OH- generate a blue precipitate.

Fe3+ and OH- form a reddish-brown precipitate.

Not enough to say more!

You mean, metathesis reaction, it should be easy to find, search for it yourself, it's troublesome to type.

Hydrogen and oxygen produce water.

Calcium ions and carbonate ions form a white precipitate.

Copper ions and hydroxide ions form blue precipitates.

water-generated; Ca(OH)2+CO2==CaCO3 +H2O produces a blue precipitate: CuO+H2SO4==CuSO4+H2O reddish-brown precipitate is FeCl3+3NaOH==Fe(OH)3 +3NaCl

Why are you so lazy to end it yourself?

The chemical equation for the generation of mercury withering.

2h2+o2=2h2o，hcl+naoh=h2o+nacl。Hydrogen has stable properties at room temperature, and can chemically react with many substances under the condition of ignition or heating.

Hydrogen and oxygen produce water under the condition of ignition, and the chemical equation is 2H2 + O2 = ignition = 2H2O.

Hydrogen and oxygen produce water under ignition conditions. Hydrogen is stable at room temperature, and can react with many substances under the condition of ignition or heating. Ignition of impure hydrogen gas to occur**, must be pure before ignition of hydrogen, similar, deuterium (heavy hydrogen.

Ignition in oxygen can produce heavy water.

The chemical formula of water is H2O, the chemical equation regarding water.

There are: 2H2 + O2 = Ignition = 2H2O, 2H2O = Energized = 2H2 +O2, Cuo + H2 = Cu + H2O, etc. Water is a colorless and transparent liquid at room temperature and is the most important component of living organisms.

Physical properties of waterThe density of the slippery water is the largest, and it is generally taken often. Solid water, or solid ice, is less dense than liquid water, so ice can float on the surface of the water. When the water freezes, the volume increases slightly.

at standard atmospheric pressure.

The boiling point of pure water is 100 and the freezing point is 0.

Definition of waterWater is a non-smuggling substance composed of two elements, hydrogen and oxygen.

The chemical formula is HO. Water is a colorless, odorless, transparent liquid at room temperature and pressure, and conductive.

Very weak electrolyte.

Water, including inorganic compounds, is an important resource for the survival of all life, including human beings, and is also the most important component of living organisms. Pure water is a very weak electrolyte with very weak electrical conductivity. Water in daily life has more anions and cations due to the dissolution of other electrolytes, so it has more obvious conductivity.

1.Acid crude base neutralization can produce water, HCl + NaOH = NaCl + H2O

2.In fact, water can be generated by digging hydroxide and hydrogen roots in the reactants.

3.The heating of the crystals produces water.

4.Water is produced by heating hydroxides, which are insoluble in water.

Such as: 2Fe(OH)3 == Heating) =Fe2O3 +3H2O5The reduction reaction of oxides with hydrogen produces water.

6.Chemical reaction: 2H2 + O2 = 2H2O (Dianyan Hui Ran) 7 metathesis 2HCl + CaCO3 = CO2 (upward arrow) + H2O + CaCl2

8.Replace Fe2O3+3H2===2Fe+3H2O

Si + 2NaOH + H2O = NaSiO3 +2H2 2Na2O2 + 2H2O = 4NaOH + O2 Good Travel 2Na + 2H2O = 2NaOH + H2 3Fe + 4H2O(G) =F3O4 + 4H2 Cao + H2O = Ca(OH)2 4Fe(OH)2 + 2H2O + O2 = 4Fe(OH)3 2Na+2H2O=H2 (Gas-type bold friend rental stool)+2NaOH2SiO3....

It can also be used for other acidic oxides to react with alkalis).
