Use the balanced equation given below to solve the problem that follows: Calculate the mass in grams of carbon dioxide produced by the reaction of 25.0 g of butane (C4H10). 2 C4H10 + 13 O2 --> 8 CO2 + 10 H2O

75.7 g CO2
18.9 g CO2
33.0 g CO2
4.73 g CO2

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
