chemical reactions

Reactant + reactant = product

State symbol - no capitals

Solid - (s)

Liquid - (l)

Gas - (g)

Aqueous(dissolved in water) - (aq)

Combustion reaction

Reaction that releases heat → exothermic

Element + oxigen → oxide

Combustion

1, Oxidation

2, Hydrocarbon(fuels) + excess oxygen → CO2 (g) + H2O(g) carbon dioxide

Complete

3, Hydrocarbon(fuels) + limited oxygen → CO(g) + H2O(g) carbon monoxide

Incomplete

carbon monoxide - bonds with the hemoglobin in your blood and prevents it from carrying oxygen

formative hw with ins history of chemical warfare

This will be next week

Need informe like with both of the subjects, format is free but in text

Redox reactions - oxidation number of reactants is changed

Reduction: the oxidation is reduced

Oxidation and the oxidation number increases

Both need to be changed for it to be one

Elements are always = 0

While compounds have anions and the other one but these have positives and negatives

Acid base neutralization

Find the acid and base,

Acid is substance that can produce or donate h2

And the base is ab alkali that will accept that h2, it normally contains OH

Neutralization reaction

The reaction between an acid and a base

And the result would be salt and water

A salt consists of a positive ion of a base and a negative ion of an acid

Salt finished in ide
