Answer:
Oxidation - reduction reaction which is called redox reaction.
Explanation:
The type of reaction that is a part of another type but treated separately is called Oxidation - reduction reaction.
Thus is because they usually involve 2 separate half reactions which are oxidation reactions that involve loss of electrons and then reduction equations which involve gain of electrons.
They are treated separately for example when sodium reacts with chlorine to form sodium chloride.
2Na + Cl2 = 2NaCl
Now, sodium undergoes oxidation by loosing elctrons and it's half reaction is;
2Na → 2Na^(+) + 2e^(-)
Meanwhile chlorine undergoes reduction by gaining electrons and its half reaction is;
Cl2 + 2e^(-) → 2Cl^(-)
Answer:
The pH of the solution is 1.38.
Explanation:
Mass of HCl = 614 mg = 0.614 g
Moles of HCl = 
Concentration of HCl :
On adding 0.01682 moles to 400 mL of water that 0.4 L of water.
![[HCl]=\frac{0.01682 mol}{0.4 L}=0.04205 M](https://tex.z-dn.net/?f=%5BHCl%5D%3D%5Cfrac%7B0.01682%20mol%7D%7B0.4%20L%7D%3D0.04205%20M)
1 mole of HCl gives 1 mole of hydronium ion and 1 mole of chloride ions in an aqueous solution.
Then 0.04205 mol/L of HCl will give:
of hydronium ions.
![[H_3O^+]=0.04205 M](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%3D0.04205%20M)
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
![pH=-\log [0.04205 M]=1.38](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5B0.04205%20M%5D%3D1.38%20)
The pH of the solution is 1.38.
Answer:
El ácido acético , denominado sistemáticamente ácido etanoico, es un compuesto orgánico líquido incoloro con la fórmula química CH3COOH (también escrito como CH3CO2H o C2H4O2
Explanation:
Cuando no se diluye, a veces se le llama ácido acético glacial . El vinagre es aproximadamente del 3 al 9% de ácido acético en volumen, lo que hace que el ácido acético sea el componente principal del vinagre, aparte del agua.
Low-cost energy. Although building nuclear power plants has a high initial cost, it's relatively cheap to produce energy from them and they have low operating costs.
Reliable.
Zero carbon emissions.
Promising future energy supply.
High energy density.
Bonding electrons are involved in chemical bonding these electrons have their valnce shell incomplete
