Three constant things are the speed of light, the Gravitational Constant and Planck's constant. c, G and h.

Some would also add to the list: Death and taxes.

What is the relationship between the gas constant (R), temperature (T), and the number of moles (n) in the ideal gas law equation, 3/2nRT?

In the ideal gas law equation, the gas constant (R), temperature (T), and number of moles (n) are related by the equation 3/2nRT. This equation shows that the product of the number of moles, the gas constant, and the temperature is equal to 3/2 times the ideal gas constant.


Vanadium at 20c is Bcc and has an atomic radius of 0.143 nm calculate a value of its lattice constant a in nanometers?

The body-centered cubic (BCC) lattice constant can be calculated using the formula a = 4r / sqrt(3), where r is the atomic radius. Plugging in the values for vanadium (r = 0.143 nm) gives a lattice constant of approximately 0.303 nm.


If 2 gases with pressures of 2 ATM and 3 ATM are mixed at constant temperature what will the total pressure be?

2 atm + 3 atm


What is the difference between dissociation constant and equilibrium constant?

The dissociation constant describes the extent to which a compound breaks apart into its ions in a solution, specifically for weak acids or bases. The equilibrium constant, on the other hand, describes the ratio of product concentrations to reactant concentrations at equilibrium for a chemical reaction.


If temperature of a gas tripled what happens to the volume?

Assuming a fixed amount of an ideal gas kept at constant temperature, then the volume is reduced to a third of its former amount when the pressure is tripled. P V = n R T = constant = k P1 V1 = k = P2 V2 P2 = 3 P1 3 P1 V2 = P1 V1 V2 V1 / 3
