Write a balanced chemical equation for the formation of silver chloride precipitate from solutions of sodium chloride and silver nitrate.
a) nacl(aq) + agno3(aq) → nano3(aq) + agcl(s)
b) nano3(aq) + agcl(s) → nacl(aq) + agno3(aq)
c) nacl(aq) + agno3(aq) → nano3(s) + agcl(aq)
d) 3nacl(aq) + agno3(aq) → nano3(aq) + 3agcl(s)

Suppose that recording station n is located 200 km north of the epicenter of an earthquake, and recording station s is located 100 km south of the epicenter of the same earthquake. which of the following statements would be true?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
