During an endothermic reaction, h for the reactants was −600 kj/mol. which of the following statements is correct about the h for the products and the comparison of the energy in bonds?

a. it is less than −600 kj/mol, and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.

b. it is less than −600 kj/mol, and the amount of energy required to break bonds is less than the amount of energy released in forming bonds.

c. it is greater than −600 kj/mol, and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.

d. it is greater than −600 kj/mol, and the amount of energy required to break bonds is less than the amount of energy released in forming bonds.

For each of the following types of reactions, write a general reaction formula in the symbolic form—for example, a + b → ab. single-displacement double-displacement synthesis decomposition

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.
