12. Which gas has the greatest kinetic energy at STP?
balandron [24]

Answer:

d. none of the above (all have the same kinetic energy)

Explanation:

The kinetic theory of gases states that the molecules of an ideal gas experience a constant random motion.

At standard temperature and pressure (STP), the kinetic energy of an ideal gas such as hydrogen, argon, neon, sodium, oxygen, helium, magnesium, beryllium, nitrogen, carbon, fluorine, chlorine etc are all the same.

The standard temperature and pressure (STP) of an ideal gas is 273K and 100 kPa.

Hence, all of the gases have the same kinetic energy at standard temperature and pressure (STP).

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

You have a glass of pure water and add acidic lemon juice to it. This means that you are adding _____ to it, and the solution wi
mr Goodwill [35]

Answer: acid; acidic

Explanation:

You have a glass of pure water and add acidic lemon juice to it. This means that you are adding ACID to it, and the solution will become ACIDIC.

Pure water has a pH value of 7

Lemon juice has a pH value less than 7 i.e acidic

Therefore, addition of lemon juice to pure water will drop the latter pH from 7 to form a final solution that is ACIDIC.
