Answer:

We associate paper money or points in video games, as molecules that make a heat transfer or an increasin in its temperature.

Explanation:

The meaning of heat is associated with an energy transfer, where for example if we put a spoon in a cup of hot drink, the drink will be transferring heat to the spoon. It is a transfer of energy between two bodies due to a difference between their temperatures.

Temperature is associated with the movement of kinetic energy of the molecules. When the temperature is higher, the kinetic energy is higher, so as more detained they are, temperature will be lower.

If we take paper money as molecules, the greater movement of money explains that we have an increase in temperature (we would be hot), even if we think of video games, for example gambling where as more points we gain, we generate an increase in the movement of "molecules".

When we use paper money to buy something we are doing a heat transfer.

We can associate terms to the Thermodynamic where

Heat = Internal energy + work

For clearance would be

Internal energy = Heat - Work

The money we use less the work we do keeps our internal energy. If in a gambling video game, we earn points over and over again, when withdrawing the prize we perform "heat transfer".

A rigid 3.80 L sealed vessel contains 0.650 mol Ne, 0.321 mol Kr, and 0.190 mol Xe. Find the density of the mixture in g/L.
Eddi Din [679]

Answer:

17.09g/L

Explanation:

Density = total mass of elements/ volume

We need to find the mass of each mixture constituents using their molar mass:

mole = mass/molar mass

For Neon (Ne) which contains 0.650mol;

0.650 = mass/20.18

mass = 0.650 × 20.18

mass = 13.12g

For Krypton (Kr) which contains 0.321mol;

0.321 = mass/83.79

mass = 0.321 × 83.79

mass = 26.89g

For Xenon (Xe) which contains 0.190mol;

0.190 = mass/131.3

mass = 0.190 × 131.3

mass = 24.95g

Total mass = 13.12g + 26.89g + 24.95g = 64.96g

Density = total mass / volume

Density = 64.96g / 3.80L

Density of the mixture = 17.09g/L

Which one would be expected to happen? If one of the buffers that contribute to pH stability in human blood is carbonic acid (H2
tino4ka555 [31]

Answer:

Option (D) is definitely the answer.

Explanation:

Before going further, it is important to know what buffers and pH represent, which are keywords to answering this question.

Buffers is a special solution that can withstand or resist changes due to pH levels which may be as a result of an introduction of acidic or basic components into the blood. In other words, they maintain the stability of pH level in the human blood.

pH blood levels on the other hand, can be grouped into three: acidity, neutrality and alkalinity. Using a pH scale, one can determine its current level. In the human blood the pH level is near neutral and needs to be on a level near 7.4 in order to avoid a high rise or a drastic fall even if acidic or basic components come in or departs the blood stream.

Therefore, if one of the buffers that contributes to pH stability in human blood is carbonic acid, which is as a result of a combination of carbon dioxide and water in the blood stream. On getting to the lungs it is converted to water and subsequently released as waste. Maintaining this stability will definitely be to decrease the concentration of carbonic acid and increase that of water instead.
