Answer:
1.89 V
Explanation:
To calculate the standard cell potential, subtract the reduction potential of the anode from the reduction potential of the cathode.
So for your calculation,
-0.22 V - (-2.11 V)= 1.89 V
Best Answer: producers use nutrients in the soil > consumers eat the producers, obtaining the energy and nutrients that the plant took > the consumer dies and is decomposed by a decomposer (usually decomposing bacteria), which replaces the nutrients back into the soil > producers use the nutrients in the soil.
now put that into your own words; if you cant, try drawing pictures to help you :) that might help you revise too, but remember to add info underneath, otherwise you might not understand it when you come back to it later
Answer:
The products will be;
CO₂ + H₂O + NaC₂H₃O₂
Explanation:
We are given;
Two reactants NaHCO₃ and HC₂H₃O₂
We are supposed to determine the products;
- We need to know that hydrogen carbonates reacts with acids to give water, carbon dioxide and a salt as the products.
Therefore;
- In this case, sodium hydrogen carbonates (baking soda) reacts with acetic acid to form water, carbon dioxide and sodium acetate.
- The equation for the reaction is;
NaHCO₃ + HC₂H₃O₂ → CO₂ + H₂O + NaC₂H₃O₂
- Therefore, the products of the complete reaction between sodium hydrogen carbonate and acetic acid are CO₂ + H₂O + NaC₂H₃O₂
A-Locations M and O are at the poles.
Explanation:
Locations M and O are located at the poles because they receive sunlight that is spread out over a large surface area. The poles receive sunlight at an angle to the surface and it causes the rays of the sun to spread out in all direction.
- At the equator, sunlight impinges directly on the surface and the solar radiation here is very much.
- It is important to know that the sun is overhead directly at the equator.
- The earth is tilted at an angle to sun and therefore, areas around the polar region will receive sunlight that is spread out in different directions over a large area.
- Away from the pole, the equator is directly facing the sun and it receives direct sunlight.

Answer:
2 FeL3+3Ag2Co3
Explanation:
in a chemical reaction, the quantity of each element does not change. thus each side of the equation must represent the same quantity of any particular element
