This is called reactivity.
the way a substance reacts with other substances is called
Chemical reaction
The substance that reacts chemically with another to produce heat is called a "reactant."
solids
A chemical reaction occurs when one substance reacts with another, resulting in the formation of new products with different properties. This change involves the breaking of existing bonds in the reactants and the formation of new bonds to create the products.
when a substance forms a new substance it is usually because it reacts under the formation of the sun when one reacts it is usually because of the heat measurments it gets per day. then when the dinasours exist again substance will reform to another in a totally different way. to try this experiment: h20 just add water
it is chemical change
Chemical equation
Copper oxide, a black substance, forms when copper reacts with oxygen in the presence of air.
Something that reacts to another substance.
It means that the substance readily reacts with other substances, often at normal temperatures, due to its chemical properties.
products
