Circuit is a closed loop through which current flows
Answer:
6.07 L
Explanation:
It appears that the reading has been made at constant pressure .
At constant pressure , the gas law formula is
V/T = constant V is volume and T is temperature of the gas.
V₁ / T₁ = V₂ / T₂
V₁ = 6.6 L ,
T₁ = 40°C
= 273 + 40
= 313 K
T₂ = 15+ 273
= 288K
V₂ = ?
Putting the values in the formula above
6.6 / 313 = V₂ / 288
V₂ = 6.07 L.
<u>Answer:</u> The half reactions are written below.
<u>Explanation:</u>
Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
We are given a chemical cell which is Fe-Sn cell. The half reaction follows:
<u>Oxidation half reaction:</u> 
<u>Reduction half reaction:</u> 
The substance having highest positive 
potential will always get reduced and will undergo reduction reaction. Here, zinc will always undergo reduction reaction will get reduced.
<u>Total cell reaction:</u> 
Hence, the half reactions are written above.
Answer:
When the energy is passed on from one trophic level to another, only 10 percent of the energy is passed on to the next trophic level.
Explanation:
Answer:
Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.
Hope this helps!!!
