9. Ms. Ramos is moving the chemistry boxes around the prep room. One of the boxes weighs 50 kg and she exerts a force of 250N as she pushes it
down and across the floor at an angle of 45°. The coefficient of friction
between the box and the floor is 0.7.

a. What is the normal force acting on the box?

b. what is the net force on the box in the horizontal direction

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

answer: i dont know the answer but this might
