An unknown mineral is placed in a bomb calorimeter for analysis. The geologist wants to find out how much heat is released during the
combustion of this unknown material. This will help her to
understand the stability of this mineral under certain temperature
conditions. She places a 1.2 g sample into the bomb calorimeter
which holds 800 g of water. The temperature within the calorimeter
raises from 24.5 °C to 32.6 °C. The C for the calorimeter is known
at 830 J/°C. Find the q, in k), of the reaction for this sample of
teria

Write a paragraph at least 10 sentences explaining how rocks are used today in society

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.
