According to given chemical reaction, one mole of carbon monoxide reacts with one mole of water results in the formation of one mole of calcium hydroxide.
Therefore, calcium monoxide and water reacts in one ratio one (1:1).
Now, in given chemical reaction, change in enthalpy is negative i.e. -65.2 kJ (less than zero).
The negative sign of change is enthalpy indicates that heat is released and the reaction in which heat is released is said to be exothermic reaction. Thus, the given reaction is exothermic i.e. heat is released.
Hence, 65.2 kJ of heat is released for every one mole of calcium monoxide which reacts is the correct statement for the given reaction.

Answer for number 1. Weight is the force of gravity. It acts in a downward direction—toward the center of the Earth.
Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences...
Thrust is the force that propels a flying machine in the direction of motion. Engines produce thrust.
2. For an airplane to takeoff, thrust must be greater than drag and lift must be greater than weight. To maintain level flight, lift must equal weight and thrust must equal drag. For landing, thrust must be less than drag, and lift must be less than weight.
3.When the forward forces are bigger than the opposing forces, you speed up (accelerate). As you go faster, the force of air resistance pushing back on you increases. Eventually, the forces become balanced (the forward forces are the same size as the opposing forces). Once the forces become balanced, your speed stays the same.
4.Every object on Earth has weight, a product of both gravity and mass. A Boeing 747-8 passenger airliner, for instance, has a maximum takeoff weight of 487.5 tons (442 metric tons), the force with which the weighty plane is drawn toward the Earth.
