<span>(4) The dissolving of the LiBr(s) in water is an exothermic process</span>
Seems to me it's graph A, based on the trends.
first one, nerve cells are used to send messages from different parts of the body to the brain.
Explanation:
It is given that the energy change is -162 kJ and work done is -194 kJ. As we know that formula for change in enthalpy is as follows.
dH = dE + W
where, dH = change in enthalpy
dE = change in energy
W = work done
Therefore, the change in enthalpy will be as follows.
dH = dE + W
= -162 kJ + (-194 kJ)
= -356 kJ
As the negative sign indicates heat is being released. Therefore, the reaction is exothermic in nature.
Thus, we can conclude that the change in energy of the gas mixture during the reaction is -356 kJ.
Answer:
seasons as summer, winter, spring, and fall ?
if yes then you could say something like,
plants lose their leaves in autumn in response to decreasing length of the day and animals find the winter hard because it is difficult for them to find food.
