Sodium carbonate (na2co3) reacts with acetic acid (ch3cooh) to form sodium acetate (nach3coo), carbon dioxide (co2), and water (h2o). a chemist carries out this reaction in a bomb calorimeter. the reaction causes the temperature of a bomb calorimeter to decrease by 0.985 k. the calorimeter has a mass of 1.500 kg and a specific heat of 2.52 j/g•k. what is the heat of reaction for this system? answer in kj

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
