<center><b>Review for Mass and Energy Page 1</b></center><br> <br> Answer the following equation showing all work<br> <br> 1. A chemical reaction absorbes 4.35Kcal of energy from 346ml of water. What is the initial temperature if the final temperature was 12.4degC?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 2. A substance occupies 2.243E-2 (2.24X10<sup>-2</sup>) liters and has a density of 0.053g/cm<sup>3</sup>. What is the mass of this substance in g? If this mass is given 45.2 cals of heat and has a specific heat of 0.456 cal/(gdegC), what is the final temperature if the initial temperature is 65.4degC?(Substance is not water)<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> Answer: 1) 25.0degC 2) 1.2g,148.8degC<br>
