The land breeze arrow is correct
The rest are incorrect.
Warm air should 'rise' by the land
This air then moves towards the sea and cools down
The cool air would then sink
Have A Nice Day ❤

Answer: -64.1 kJ.
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done by the system=
{Work is done by the system is negative as the final volume is greater than initial volume}
w = -855 Joules = 0.855 kJ (1kJ=1000J)
q = -65.0 kJ {Heat released by the system is negative}
Thus the change internal energy (ΔE) for a system that is giving off 65.0 kJ of heat and is performing 855 J of work on the surroundings is -64.1 kJ.
I think you want to ask the complete ionic equation and net ionic equation. For complete ionic equation: 3Ba2+ + 6Cl- + 2Al3+ + 3SO42- -->3BaSO4 + 2Al3+ + 6Cl-. For net ionic equation: 3Ba2+ + 3SO42- -->3BaSO4.
On the Moon<span>, there is (as on </span>Earth) day and night (though the day is as long as month onEarth<span>) and no spot remains </span>dark<span> for longer (except for the pole caps as on </span>Earth<span>). There is, of course, the far </span>side of the Moon<span>, most of which is invisible from </span>Earth.
