Answer:
Because in elastic collisions there is no heat emission or absorption.
Explanation:
A collision is considered elastic when the total kinetic energy of the study system is conserved during the collision. Since the total kinetic energy is conserved, heat is not emitted or absorbed during the collision. Since the emission or absorption of heat is what produces changes in temperature, If the system remains at a constant temperature, there were only elastic collisions.
Answer:
The reducing agent is Hg (mercury) and the oxidixing agent is Cl (chlorine)
Explanation:
first find the oxidation charges of each of the different ions. All elements that are alone have a charge of 0. As you compare the reactants and products we can see that the chargers of Hg and Cl have changed.
Hg went from a charge of 0 to a charge of +1
Cl went from a charge of 0 to a charge of -1
remember when a substance gains electrons it is reducing and when a substance is losing electrons it is oxidizing.
