<span>The earth's crust is primarily composed of a mineral named feldspars. Feldspars are the most common mineral by a margin of 30% more than the second most common mineral, quartz. Together, both of these minerals make about 50% of our Earth's crust.</span>
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.
When a man travels from earth to space, the mass of the person, defined as the amount energy a matter has remains constant. However, when he moves to space, gravity decreases until such time that there is no gravity that acts on the person. Weight thus changes or decreases until the point of state called weightlessness.
