There are actually five things that are common to all chemical reactions. These are change of color, change of state, evolution of a gas, formation of a precipitate, and change in temperature.
New compound is created using building block from depleted compound.
Mass and Energy in conserved before and after reaction.
If the energy or mass is not conserved then something is wrong in the balancing of equation.
All chemical reactions involve the breaking of chemical bonds and the formation of new and different chemical bonds.
What kind of elements are least often involved in single-displacement reactions
They all form a new substance.

solid, liquid, gas, and aqueous
they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells. they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells.
There are many chemical reactions that relase enegy but do not involve Oxygen at all. The decomposition of Nitrogen Triodide is an example. 2NI3 -> N2 + 3I2
Yes, chemical weathering involve chemical reactions.
Metabolism
metabolism
All chemical reactions need a certain amount of activation energy to get started.

enzymes
Usually, only electrons participate in chemical reations. The other subatomic particles play a larger role in nuclear chemistry.

Dissolution, Mineral conversions, Exchange reations, Redox reactions.
solid, liquid, gas, and aqueous
yes it does because the chemical reations are not uised to be freezing
no
