In the mond process for the purification of nickel, carbon monoxide is reacted with heated nickel to produce ni(co)4, which is a gas and can therefore be separated from solid impurities: ni(s) + 4co(g) ⇌ ni(co)4(g) given that the standard free energies of formation of co(g) and ni(co)4(g) are −137.3 and −587.4 kj/mol, respectively, calculate the equilibrium constant of the reaction at 64.0°c. assume that δg o f is temperature-independent.

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. her friend, a hockey player, then shoots a hockey puck at each shoe. the first puck immediately comes to rest after it collides with the left shoe. the second puck rebounds after it collides with the right shoe. if each hockey puck has the same incoming speed, which shoe has greater speed after the collision? the right shoe. both shoes have the same speed. the left shoe.

There are two routes similar in terrain; however, one route has an incline of approximately 28 degrees, and you must decide on which route to take. what is the maximum road grade that your fully loaded ecv can climb?

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v
