Q6) Ahmad has two unlabeled balloons, one filled with hydrogen gas and the second filled with neon gas.

He places both balloons in a chamber of Helium to help him identify

neon and hydrogen.

a.

Predict what will happen to help Ahmed identify the element

in each of the balloons when it is placed in Helium. Explain your

answer. Give your evidence

Oxygen has a molar mass of 16.00 g/mol. One mole of CO2 contains 32.00 grams of oxygen. One mole equals 22.4L at standard temperature and pressure. 0.60L CO2 equals 0.0268 mol at STP

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
