Answer:
Solubility
Explanation:
Solubility is the only thing that you can hold in your hands and touch (you can't hold reactivity or flammability). Physical = you can touch and hold it
Entropy change is defined only along the path of an internally reversible process path.
<h3><u>What is Entropy Change </u>?</h3>
- Entropy is a measure of a thermodynamic system's overall level of disorder or non-uniformity. The thermal energy that a system was unable to use to perform work is known as entropy.
- Entropy Change is a phenomena that measures how disorder or randomness have changed inside a thermodynamic system.
- It has to do with how heat or enthalpy is converted during work. More unpredictability in a thermodynamic system indicates high entropy.
- Entropy is a state function, hence it is independent of the direction that the thermodynamic process takes.
- The rearranging of atoms and molecules from their initial state causes the change in entropy.
- This may result in a decrease or rise in the system's disorder or unpredictability, which will, in turn, result in a corresponding drop or increase in entropy.

If you start with the mass of a substance, divide it by its molar mass to find the number of moles of the substance. Then, multiply the number of moles by Avogadro's number, 6.022*10^23, which gives the number of particles per mole of a substance.
Example:
Find the number of atoms in 10 g of CO2.
The mass of a single mole of CO2 is 54 g/mol. You can get this value by adding up the molar masses of the atoms in CO2(12+16+16).
Then divide 10 g by 54 g/mol to get the number of moles of CO2 in 10 g, which is 0.19 mol.
Finally, multiply 0.19 by Avogadro's number to get 1.1*10^23 molecules of CO2.
Answer:
A. the temperature at which the motion of particles theoretically ceases.
Explanation:
Absolute zero is the same as 0 K (or zero Kelvin). At this point, the temperature cannot get any lower, and it is incredible difficult to get something to this low low temperature. The particles theoretically stop moving at 0 Kelvin aka absolute zero.
Answer:
A typical laser pulse used in MALDI is about 60 microjoules/pulse at 337 nm. At 337 nm the power is about 6 x 10^-19 J/photon. Doing the math suggests that of 10^14 photons are in a typical desorption pulse
