Answer: increases
Explanation:
Matter exists in three different states, they are solids, liquids and gases. And each of them contains molecules with a certain amount of kinetic energy.
Hence, the addition of heat changes a substance from a liquid to a gas through a process called vaporization, whereby liquid molecules on changing to gases acquire a higher kinetic energy, and move more freely within the containing vessel.
Thus, the higher kinetic energy explains the increase in the average distance between molecules.
Yo u need to know it’s molar mass, balanced equation
Answer:
Gas/vaporization
Explanation:
The most stare has the high volume is the gas state. So the answer is between vaporization and sublimation
First, convert 2.0 mL of AlCl3 to grams using the density, which is 2.48g/mL. So 2.48g/mL * 2.0 mL = 4.96g. Then find the molar mass of aluminum chloride and divide 4.96 by this number, which is 133.34g. 4.96g*(1mol/133.34g) = .0372 mols AlCl3. Check for significant digits though.
Answer:
Explanation:
Hello,
In this case, for the given chemical reaction, the law of mass action at equilibrium results:
Next, in terms of the change due to reaction extent, it is rewritten, considering an initial concentration of HCl of 0.25M (1mol/4L), as:
Thus, solving for via quadratic equation or solver, the following results are obtained:
Clearly, the solution is as the other result will provide a negative concentration for the hydrochloric acid at equilibrium, thereby, its equilibrium concentration turns out:
Best regards.
