Some theories of aging suggest that free radicals cause certain diseases and perhaps aging in general. as you know from lewis theory, such molecules are not chemically stable and will quickly react with other molecules. free radicals may attack molecules within the cell, such as dna, changing them and causing cancer or other diseases. free radicals may also attack molecules on the surfaces of cells, making them appear foreign to the body's immune system. the immune system then attacks the cells and destroys them, weakening the body. draw lewis structures for each of the following free radicals implicated in this theory of aging.
a. o2-
b. o-
c. oh
d. ch3oo(unpaired electron on terminal oxygen)

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

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
