A34.87 g sample of a substance is initially at 27.1 c. after absorbing 1071 j of heat, the temperature of the substance is 145.0 c. what is the specific heat (sh) of the substance?
sh= j / g * c

Find the number of moles of argon in 364g of argon.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
