Four gases are described below:Gas A: 5 liters at 20 °C
Gas B: 5 liters at 10 °C
Gas C: 5 liters at 40 °C
Gas D: 5 liters at 30 °C

Which gas has the greatest average molecular kinetic energy?

Answer:

some bonds are broken and new ones are formed. Now you are ready to learn more about those bonds. Chemical bonds are attractions between atoms. They are simply attractive forces (between the + nucleus of one atom and the - electrons of a neighboring atom) that hold groups of atoms together and make them function as a unit.

Answer:

Temperature dependency is responsible for the process that hot water freeze faster than cold water.

Explanation:

The effect given above is called Mpemba Effect. According to this idea hot water freezes more quickly as compared to cold water. But until now there is no convincing explanation for this strange phenomenon.  One idea is that hot containers make better thermal contact with a refrigerator and so conduct heat more efficiently because a good conductor is good fro the transfer of heat. Another idea about this effect is that warm water evaporates more quickly and since this is an endothermic process, it cools the water making it freeze more quickly.

warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly.

Answer:

3Mg + Fe₂O₃ → 3MgO + 2Fe.

Explanation:

• To balance the equation, you should apply the law of conservation of mass for the equations.

• The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).

• The balanced equation is:

3Mg + Fe₂O₃ → 3MgO + 2Fe.

That 3.0 mole of Mg react with 1.0 mole of Fe₂O₃ to produce 3.0 moles of MgO and 2.0 moles of Fe.

• The no. of all atoms is the same in both of reactants and products side.

Mg (3), Fe (2), and O (3).
