1. what is the lewis dot structure for nci2h?

answer:

electrons exist outside of an atom 's nucleus and are found in principal energy levels that contain only up to a specific number of electrons. lewis symbols are diagrams that show the number of valence electrons of a particular element with dots that represent lone pairs.

explanation:

h let me think

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.
