Answer
A. Metals A and metals B
Explanation
Heat transfer takes place whenever there is temperature difference. When two bodies of different temperatures are brought together, heat energy will move from one body to the other until equilibrium temperature is reached.
In our case, heat transfer will take place in all four metals.
Metal A will transfer heat to the water since it's temperature is higher than that of water.
Metal B will also transfer heat to the water since it's temperature is higher than that of water.
Metal C will get heat from the water since it's colder than the water.
Metal D will also get heat from the water since it is colder than water.

B) The substances produced are identical to the substances that reacted except that they're isomers.
C) The total mass of the reacting substances is the same as the total mass of the substance produced by the reaction.
D) The chemical properties of the substances produced by the reaction are different from those of the reacting substances.
Answer: B) The substances produced are identical to the substances that reacted except that they're isomers.
Explanation: Chemical change is a change in which atoms of the reactants are rearranged ,thus leading to formation of new products.
The new substances formed are different compounds from the original reactants and thus they have different properties.
This is an example of chemical reaction in which the bond between chlorine molecule is broken and a new bond between sodium and chlorine gets formed.
formed is an ionic compound whereas chlorine is a covalent compound and sodium is a metal.
