Temperature means, in this context, movement.
Condensation can be explained by the reduction of temperature of the system. This effect make possible the cohesion forces increases. In other words, the result is coalescence by attractive forces.
Answer:
0.99%
Explanation:
The Henderson-Hasselbalch equation relates the ratio of the ionized to the non-ionized form of an acid as follows:
pH = pKa + log([A⁻]/[HA])
Inserting the values for pH and pKa and solving gives:
7.4 = 5.2 + log([A⁻]/[HA])
2 = log([A⁻]/[HA])
[A⁻]/[HA] = 100/1
The percentage of the weak acid in non-ionized form (HA) is then calculated:
[HA]/([A⁻] + [HA]) = 1/(100+1) x 100% = 0.99&
1. I think you chose the right answer, the equation has the states of the reactants and products.
2. I think you chose the right answer.
3. I think you also chose the right answer. Assuming that the Hrxn is written as kJ per mol CH4
4. Heat of solution is the enthalpy change associated with dissolving a solute in a solvent. I think the first choice is the right one.
5. I think you chose the right answer.
