molecules compised of only two atoms of the same element (HOFBrINCl)
Matter is neither created or destroyed, and in any chemical reaction the total mass of the reactants must be equal to the total mass of the products
two simple reactants combine to form a larger or more complex product (A + B = AB)
e.g sodium + chlorine gas = sodium chloride
a complex reactant breaks down to make two or more simpler products (AB = A + B)
a non- metal may displace another non metal from a compound (AB + C = AC + B)
a metal may displace another metal or hydrogen from acids or water (AB + E = EB + A)
two compounds react to form two new compounds
AB + CB = AD + CB
the reaction of carbon with oxygen, if carbon monoxide or soot is formed it is incomplete combustion
ionize to produce hydrogen ions in a solution (forming ions from a covalent bond)
Oxoacids fo when hydrogen combines with a polyatomic ion that contains oxygen
Binary acids form when hydrogen combines with a non metal, usually a halogen
form when a metal combines with the polyatomic ion hydroxide (OH-)
they break down when dissolved in water to produce positive metal ions and negative hydroxide ions
sour, no specific texture, conductive, corrodes tissues and metals, makes hydrogen gas when reacting with metal, turns blue litmus red, colourless ph, 0-7
bitter, slippery, conductive, corrodes only tissues, no reaction with metal, turns red litmus blue, pink with phenolpthalein, 7-14 ph range
changes colour depending on if its an acid or base, phenolpthalein, litmus paper, and cabbage juice
the number of hydrogen ions and hydroxide ions must be the same to be neutral. Balance acids and bases to make them neutral, this is a double displacement reaction
