3. The electrolyais of water produces oxygen gas at the rate of 32.5 mL/min in a certain experiment. What volume of oxygen gas can be produced in 7.50 min?

243.75 mL

Explanation:

In 1min 32.5 mL of oxygen

In 7.5 min electrolysis of water produces

(32.5mL × 7.5 min)/ 1min

= 243.75mL

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
