Which of the following correctly describes the structure of an atom where electrons are found? * A. Electrons are found in energy levels inside the nucleus of an atom.
B. Electrons are found floating in a cloud inside the nucleus of an atom.
C. Electrons are found outside the nucleus orbiting in a circular pattern.
D. Electrons are found floating in a cloud outside the nucleus of an atom.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Explain why scientists use shared characteristics to make cladograms.

The table describes how some substances were formed substance 19 description formed by boiling pure water formed by combining three hydrogen atoms to every nitrogen atom formed by adding 5 g of sugar to 1 l of water formed by compressing carbon under high pressure based on the given descriptions, which substance is most likely a mixture?
