351 Joules of energy was released when a 12 gram sample of unknown metal with an initial temperature of 90 °C was cooled down to 25 °C Describe the direction of heat flow between the metal and the water. (4 pts)

Naturely, the direction of the heat flow is from zone of high temperature to zones of low temperature. Hence, the direction of heat flow is from the sample of unknown metal and surrounding water until thermal equilibrium in the water-sample system is reached.

Explanation:

Naturely, the direction of the heat flow is from zone of high temperature to zones of low temperature. Hence, the direction of heat flow is from the sample of unknown metal and surrounding water until thermal equilibrium in the water-sample system is reached.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
