Write the letter T or F inside each box after deciding which statement is true or false. Then on the 3 box, write the letter of your choice based on the given instructions. MODIFIED TRUE OR FALSE.: A if both statements are true B if the 1 statement is false and the 2nd statement is true C if the 1st statement is true and the 2d statement is false D if both statements are false 1. Thermodynamics is a branch of physical chemistry that deals with thermal changes. Thermochemistry determines the quantities of energy emitted or absorbed. 2. Changes that seem to happen by themselves in one direction are spontaneous reactions. The meiting of ice is an exothermic reaction. 3. A portion that is singled out in a study where energy can be transferred back and forth is called the surroundings. A thermochemical system where neither energy can be exchanged with its surroundings is called a closed system. 4. Compounds formed from their elements in exothermic reaction have negative AH, lonic compounds…
