A sample of propane (C3H8) has a mass of 0. 47 g. The sample is burned in a bomb calorimeter that has a mass of 1. 350 kg and a specific heat of 5. 82 J/(g • °C). How much energy is released by the reaction if the temperature of the calorimeter rises by 2. 87°C? Use q equals m C subscript p Delta T. 7. 85 kJ 10. 6 kJ 22. 5 kJ 47. 9 kJ.

Order the following from smallest to largest atom, electron, quark, proton, neutron, molecule, nucleus

Is this a scientific model? use complete sentences to explain why or why not. a graphic organizer showing the water cycle i need : ( asap i go it never mind

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
