What number and types of atoms occur in a formula unit of Ca(NO3),? Select one:
. 1 calcium atom, 2 neon atoms, and 3 oxygen atoms
. 1 calcium atom, 2 nitrogen atoms, and 6 oxygen atoms
. 1 carbon atom, 1 neon atom, and 6 oxygen atoms
. 1 carbon atom, 1 nitrogen atom, and 3 oxygen atoms​

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

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.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
