Acar travels at a speed of 80 km/h. which of the following is correct to convert the speed of the car to hm/s? [1 km = 10 hm, 1 h = 3600 s] a divide 80 by 3600 b multiply 80 by 3600 c divide 80 by 10 and multiply the result obtained by 3600 d multiply 80 by 10 and divide the result obtained by 3600

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)

Reactions in cells take place at about a. 40°c b. 0° c. 100°c d. 60°c

Describe the process that was used in this lab to create magnesium oxide, specifically identifying the type of chemical reaction. explain why the product had a higher mass than the reactant, and how this relates to conservation of matter.
