During an investigation, a student mixes two liquids in a beaker. The student recorded the following observations in her science notebook. I. Both liquids are clear prior to mixing.
II. Both liquids are room temperature prior to mixing.
III. The liquid turned pink when mixed.
IV. The temperature of the liquid increased.
V. Over time, a white solid formed at the bottom of the beaker.

Required:
Write down the evidence of a chemical reaction.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

b is the correct

the answer is either b or c

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
