In a science project I’m doing, I’m putting a powder on peoples hands and seeing if a warning changes the amount of powder spread. What would be the variables in this project? Please help me lol, thank you!(i had no idea what category this goes in)

You may expect bonds between two atoms which each have n covalent lonic metallic hydrogen

Which type of precipitation would most likely form when the surface air temperature is slightly below freezing and the air temperature increases as you move upward away from the ground?

Give the set of reactants (including an alkyl halide and a nucleophile) that could be used to synthesize the following ether: draw the molecules on the canvas by choosing buttons from the tools (for bonds and charges), atoms, and templates toolbars, including charges where needed. ch3ch2och2ch2chch3 | ch3
