Answer: D!! ( difference in the potential energy of the reactants and products )
Explanation:
i have the same test
Widespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica and Australia was one of the major pieces of evidence for the theory of continental drift.
A. soluble.
The are solubility rules that predict precipitation reaction.
Metallic bonds<span>, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize</span>
A change in temperature is a sign that a chemical reaction has occurred. This occurs in an endothermic reaction. An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.
Hopefully im not too late :/
