Use the table below to rank the following molecules from non-polar covalent to ionic: CO2, O2, H2O, CH4, HF. Which one would be the second from the left? Types of Bonds

Bond Type Electronegativity Difference

Non-Polar Covalent less than 0.4

Polar Covalent 0.4 to 1.6

Ionic greater than 1.6

A) O2

B) CO2

C) H2O

D) CH4

Which is mostly likely why many scientists reject the cold fusion theory

Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.

What will most likely happen when two bromine atoms bond together?
