The following molecule can be synthesized from an epoxide and alkyllithium reagent, followed by aqueous workup. however, there are two ways in which this molecule can be formed. in one approach, the epoxide has a higher molecular weight than the epoxide used in the other approach. draw both versions in the boxes below. draw the carbon-lithium bond as a covalent bond. part 1: draw the combination of epoxide and alkyllithium reagent that uses a lower molecular weight epoxide. part 2: draw the combination of epoxide and alkyllithium reagent that uses a higher molecular weight epoxide.

In this thread, i would like you to comment on the nature of light and how operation of telescopes. light has a duality of a particle and a wave; which one affects your life? also how does light interact with optics inside telescopic systems? answer these questions in two paragraphs. then respond the another students response.

Apoint charge +q is at the origin. a spherical gaussian surface centered at the origin encloses +q. so does a cubical surface centered at the origin and with edges parallel to the axes. select "true" or "false" for each statement below. the electric flux through the spherical surface is greater than that through the cubical surface. suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. the flux through both surfaces remains unchanged. the area vector and the e-field vector point in the same direction for all points on the spherical surface. the e-field at all points on the spherical surface is equal due to spherical symmetry. the flux through the spherical gaussian surface is independent of its radius.

What does the negative sign in f = –kx mean?
