Answer:
molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
Answer:
Specific heat capacity formula
Explanation:
The heat capacity gives the exact heat energy at which a given mass of a substance is heated from one temperature to another.
This formula can help determine how much heat is gained or lost during the reaction and is given by:
Q = mcΔT
where:
Q = heat energy in Joules or Calories
m - mass of the substance (g)
c = Specific heat capacity (J/kg°C)
ΔT = change in temperature = (final temp - initial temp) (°C)

Answer:
Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Minerals that have the same chemistry but different crystal structures are called polymorphs.
Answer:
Synthesis reactions. Decomposition reactions. Combustion reactions.
Explanation:
Synthesis reactions. - Two or more reactants combine to make 1 new product
Decomposition reactions. - A single reactant breaks down to form 2 or more products.
Combustion reactions. - A single element or compound combines with oxygen gas releasing energy. This rapid oxidation is called burning.
