Question 25 2 pts Butane releases heat when it burns. 2C4H10(g) + 1302(g) → 8C02(g) + 10H2O(1) AHrxn=-5754 kJ How much heat would be released if 0.171 mol of butane (C4H10)is combusted? Your answer should have 3 significant figures. Question 26 2 pts Name 3 ions that have the condensed electron configuration equal to Ne. Input the answers with the symbol and charge with no space between-for example, H+ or Ba2+.
14. (4 pts.) Butane (C4H10) reacts with oxygen (O2) according to the reaction: 2C4H10(g) + 1302(g) → 8C02(g) + 10H20(1) A4.00 L container is filled with 0.750 atm butane (CH2o). a. What pressure of Oz must be added to the container to react with butane? b. What would be the total pressure of the container after the O, has been added?
