Answer:
Explanation:
Zn + 2HCl ⇄ ZnCl₂ + H₂
A system in equilibrium will try to annul any stress placed on the system for it to maintain the equilibrium position.
For reactions in which concentration changes are effected, the equilibrium shifts to the right if the concentration of species on the reactant side is increased and vice versa.
In the reaction above, if the concentration of the HCl is decreased, the equilibrium will shift to the left in order to increase back the concentration of both the Zn and HCl. Therefore, the acid HCl will become more acidic.
Lipids serve as structural components of cell membranes, function as energy storehouses, and function as important signalling molecules. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.
Hope this helped :)
In order to convert mm³ to m³, we use the conversion factor of 1m = 1000 mm. Also, the conversion factor of mm³ to cm³, we use the factor of 1cm = 10 mm.
= (0.45 mm³) x (1 m/ 1000 mm)³ = 4.5 x 10^-10 m³
= (0.45 mm³) x (1 cm/10 mm)³ = 4.5 x 10^-4 cm³
Thus, the answer is letter B.
Population is my helpful answer
Answer:
The biodiversity of an area is literally the number of species, both plant and animal, inhabiting the environment being examined. When a species is no longer found in a region, it is locally extinct.
