Jlenok [28]

The element that has been reduced in the chemical equation is \rm Cl_2.

The given reaction has been:

\rm Mg\;+\;Cl_2\;\rightarrow\;Mg^2^+\;+\;2\;Cl^-

The reaction has been the redox reaction, in which the one of the reactant has been oxidized, and the other has been reduced in the chemical reaction.

<h3>Reduction in the reaction</h3>

The reduction has been defined as the gain of electrons. In the given reaction, the Mg loses 2 electrons and has been converted to the Mg ion.

Thus, Mg has been oxidized in the reaction.

The Cl has been present as the diatomic molecule and with the gain of two electrons from the Mg it has been converted to two chloride ions.

Thus, the element that has been reduced in the chemical equation is \rm Cl_2.

If the grass contains 220,000 kcal of energy, who much energy will be available to the owl?
Anni [7]

Answer:

Generally, consumers only receive 10% of the energy from what they eat. So, if the grass had 220,000 kcal of energy, then the cow would receive 10% of that -  200kcal. And then when a human eats the cow, it will only receive 10% of the cow's energy. This is because within a food chain, energy is lost as organisms use their energy to survive - like moving and producing heat (if endothermic). So consumers do not get 100% of their food's energy. Hope this helps a little.
