Answer:1Zn+2HCl------1ZnCl2+1H2

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus zinc can easily lose electrons as compared to hydrogen and result in the formation of zinc chloride and hydrogen.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

What order did the rock layers and features form in this photograph (listed from oldest to youngest)?
Akimi4 [234]
As newer rock layers form, they overlap with the ones with the pre-existing ones. Therefore, when looking for older rock layers, we would look for the ones that are deeper beneath the surface of the earth. On the other hand, newer rock layers are found at the top. This is also observed in the fact that oil rigs dig very deep into the ground to access the layers that are millions of years old.

What happens to the size in each level in the idealized pyramid as energy is transferred through the trophic levels?
Fed [463]

Answer:

The size is reduced as 80-95% of the available energy at one trophic level is not transferred to the next

Explanation:

There is loss of energy as it is transferred between trophic levels. The decrease in energy as it moves up the pyramid is due to energy loss as metabolic heat when one organism is consumed by another from the next level as it moves up the trophic levels.
