Answer:
27 days, 7 hours and 43 minutes.
Explanation:
To complete a full orbit around Earth, it takes 27 days, 7 hours and 43 minutes for the Moon. This is called sidereal month and is measured by the Moon's position relative to distant *fixed" stars.
I believe that the answer would be true

just read the explanation.
Explanation:
1.Maintaining a healthy, perennial plant cover.
2.Mulching.
3.Planting a cover crop – such as winter rye in vegetable gardens.
4.Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
Hope this helps. :)
Explanation:
According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
As the given reaction is as follows.

(a) When increase the temperature of the reactants or system then equilibrium will shift in forward direction where there is less temperature. It is possible for an endothermic reaction.
Thus, formation of
will increase.
- (b) When we decrease the volume (at constant temperature) of given reaction mixture then it implies that there will be increase in pressure of the system. So, equilibrium will shift in a direction where there will be decrease in composition of gaseous phase. That is, in the backward direction reaction will shift.
Hence, formation of
will decrease with decrease in volume.
- When we increase the mount of
then equilibrium will shift in the direction of decrease in concentration that is, in the forward direction.
Thus, we can conclude that formation of
will increase then.
