H2+i2->2hi
Combination of Hydrogen and iodine
iodine reacts with chlorine gas produces iodine trichloride I + Cl2 -->ICl3 now you have to balance the equation and you get: 2I + 3Cl2--> 2ICl3 Note: iodine trichloride is a molecular compound and that is why they used a prefix on the chloride. Therefore iodine trichloride just means 1 iodine and 3 chlorines resulting in ICl3. Also because chlorine is a diatomic element it needs to have a subscript of 2.
Iodine and hydrogen have a valence of 1- and both exist naturally as diatomic molecules. ie: I2 and H2 (most commonly iodine gas and hydrogen gas respectively) Therefore the formula is: HI
Br2 + CaI2 ----> CaBr2 + I2 bromine and iodine are diatomic molecules
H2 + F2 -> 2HFhydrogen + fluorine -> hydrogen fluorideOne molecule of hydrogen reacts with one molecule of fluorine to produce two molecules of HF.
H2o+no2
Combination of Hydrogen and iodine
2h2o --> 2h2 + o2
H2,g + I2,s --> 2HIg
Hydrogen + oxygen → water2H2 + O2 → 2H2ORemember to balance the equation

Solid lithium iodide decomposes into solid lithium and iodine gas.

This equation is I2 (s) + 4 Cl2 (gas) => 2 ICl4 (s).
The chemical equation for hydrogen to water vapor is not possible as stated. In order for hydrogen to form water in any physical state, it must combine with oxygen. The following are the word equation and the chemical equation for hydrogen and oxygen combining to form water. Hydrogen gas plus oxygen gas produces water. 2H2 + O2 --> 2H2O
the balanced equation is N2 + 3H2 = 2NH3
2 oxygen, 4 hydrogen
