Which characteristic is typical of metals? a. they are brittle. b. they do not conduct electricity. c. they are highly soluble in water. d. they are malleable.

D. They are malleable.

Option (D) is the correct answer.

Explanation:

Metals are the species which have excess of electrons. Metals are placed from left side to more than middle side of the periodic table.

Some properties of metals are as follows.

Thus, we can conclude that out of the given options, characteristic they are malleable is typical of metals.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
