Answer:
the volume stays the same, but the shape changes to fit the new container
Explanation:
because the same amount/volume of liquid is being placed in a new container, the new container has a different shape to the old, thus changing the liquids shape but not volume.
Answer:
Solute
Explanation:
The salt is the substance that dissolves in hot water (solute)
Explanation: In solids, particles are very closely packed in an orderly arrangement in a lattice and only vibrate in fixed positions. The forces of attraction between them are very strong. This allows them to overcome the forces of attraction that hold the other phases closer together
Answer : The change in enthalpy for the reaction is, 175 kJ
Explanation :
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The main reaction is:

The intermediate balanced chemical reaction will be,
(1)

(2)

(3)

Now we are dividing reaction 1 by 2, dividing reverse reaction 2 by 2 and then adding all the equations, we get :
(1)

(2)

(3)

The expression for change in enthalpy of the given reaction is:



Therefore, the change in enthalpy for the reaction is, 175 kJ
