The thermometer reading will change from reading the solution temperature.
Adding more solute or more solvent can change a solution.
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
If Russian people did not believe that change was necessary, it might be difficult to implement any reforms or improvements in the country. Without a sense of urgency or motivation for change, progress and development could be hindered, leading to stagnation and potential challenges in addressing issues or adapting to new circumstances.
He made them do what he said!
They believe change is necessary to make society more equal.
The purpose is to obtain a homogeneous mixture.
Define problem, develop model, optain data, develop solution, solve equtions, test solution, analize results, implement results and change if necessary
i don't believe it does
A solution does not have a chemical change, but it does have a physical change in state.
the Russian people were not pleased.
sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
The thermometer reading will change from reading the solution temperature.
The answer is Perestroika
it is a chemical change
