Can you please help me understand how to solve this answer. A balloon is being inflated to its full capacity by heating the air inside of it. The volume of the balloon changes from 4.30 x 10^9 mL to 4.80 x 10^9 mL by the addition of 1.6 x 10^8 J of heat energy. If the balloon expands against a constant pressure of 1.00 atm, calculate (delta) E for the process.
A student dissolves 14.9 g of sodium hydroxide (NaOH)in 300. g of water in a well-insulated open cup. He then observes the temperature of the water rise from 21.0 °C to 33.2 °C over the course of 5.4 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NaOH(s) → Na"(aq) + OH (aq) You can make any reasonable assumptions about the physical properties of the solution, Be sure answers you calculate using measured data are rounded to 3 significant digits. Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction.
