When 2.50 g of a certain hydrocarbon was completely combusted in a "bomb (constant-volume) calorimeter" with a heat capacity (excluding water) of 350 j/°c and which contained 2.00 liters of water (density = 1.00 g/ml and specific heat capacity = 4.184 j/°c•g), the resulting temperature change was measured to be 5.52°c. calculate the thermal energy (in kj) released per gram of hydrocarbon combusted. (1) 48.1 kj/g (2) 0.773 kj/g (3) 19.2 kj/g (4) 18.5 kj/g (5) 46.2 kj/g

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.
