Depending on what you are using the chemical could react in an explosion if the substance is not known
Answer: hot
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and the system will be cold and surroundings will be hot.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and the system will be hot and surroundings will be cold.
As heat is absorbed, the reaction is endothermic and the system will feel hot.
Answer:
Gas liquid solid
Explanation:
gases have a weak potential since they have a weak bond between molecules while in solids it's the strongest making them vibrate in a fixed position
The number of atoms in a molecule varies depending on the specific molecule formed. As a rule of thumb, a molecule must be composed of at least two atoms with no maximum amount of atoms as long as all the atoms in the molecule are bonded together somehow.
The answer: DNA stores an organism’s genetic code.
