Answer: the oxidation of the copper (it turning green)
Explanation:
The electron that have the most energy in an atom is
electrons in the outer most shell
<u><em> Explanation</em></u>
Electrons in the outer shell have higher energy and they travel fur from the nucleus than those in the inner shells.
As the electrons move away form the nucleus its energy become less and less negative, that is their energy increases.
Uranium is a radioactive substance, which is extremely reactive. As a consequence, it cannot be found in the environment in its elemental state. During uranium, mining disturbances can influence both the quality and quantity of the surface water.
Several of the effects of uranium mining are identical to those experienced in other kinds of mining.
Due to the harmful effects of radioactive substances, the uranium mining for the use of nuclear energy has the greatest environmental influence.
Answer:
C₈H₁₈ + 25/2O₂ —> 8CO₂ + 9H₂O
2C₈H₁₈ + 25O₂ —> 16CO₂ + 18H₂O
Explanation:
The reaction above is simply termed combustion reaction in which an organic compound react with oxygen to produce carbon dioxide and water. Thus, we can obtain the balanced equation for the reaction reaction as follow:
C₈H₁₈ + O₂ —> CO₂ + H₂O
There are 8 atoms of C on the left side and 1 atom on the right side. It can be balance by writing 8 before CO₂ as shown below:
C₈H₁₈ + O₂ —> 8CO₂ + H₂O
There are 18 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 9 before H₂O as shown below:
C₈H₁₈ + O₂ —> 8CO₂ + 9H₂O
There are 2 atoms of O on the left side and a total of 25 atoms on the right side. It can be balance by writing 25/2 before O₂ as shown below:
C₈H₁₈ + 25/2O₂ —> 8CO₂ + 9H₂O
Thus, the equation is balanced!
The above equation can also be written as follow:
C₈H₁₈ + 25/2O₂ —> 8CO₂ + 9H₂O
Multiply through by 2
2C₈H₁₈ + 25O₂ —> 16CO₂ + 18H₂O
Answer:
on the right side of the equation and are called products
Explanation:
Reactants are on the left side of the equation. When reactants react, they give products.
Products formed are at the right side of the equation.
They are directed as reactant to product using an arrow pointing towards the products.
New substances formed are called products. Several By-Products can also be formed . They are also on the right hand side.
