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.

elements make up everything, and they combine to make compounds.

the answer is c

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
