Draw resonance structures for the following compound: First, add curved arrow(s) to show the resonance using the following pattern: a pi bond between two atoms of differing electronegativity. Modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds.

In a popular classroom demonstration, solid sodium is added to liquid water and reacts to produce hydrogen gas and aqueous sodium hydroxide. part a write a balanced chemical equation for this reaction. express your answer as a chemical equation. identify all of the phases in your answer.

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
