Dumping waste is different from dilution and dispersion. Dumping waste is directly disposing your waste and not regulating its effect to the environment. Dilution is done usually before waste water disposal, meaning adding water to the waste to minimize its concentration.
I think Batteries you can connect a batteries to a circuit and reaction between chericals
Answer:
SEM provides detailed high resolution images of the sample by rastering a focussed electron beam across the surface and detecting secondary or backscattered electron signal. An Energy Dispersive X-Ray Analyzer (EDX or EDA) is also used to provide elemental identification and quantitative compositional information.
It is to be assumed that the unit of the given concentration is in molarity. To determine the number of moles given molarity and volume, we use the equation,
m = (M)(V)
volume should be in liters. Substituting the known values,
m = (0.350)(0.40 L)
m = 0.14 mols
Then, multiply the number of moles by the molar mass of KOH which is equal to 56.1056 g/mol.
mass = (0.14 mols)(56.1056 g/mol)
mass = 7.855 grams
Answer: 7.855 grams
Answer:
Cl⁻ is the reducing agent.
Explanation:
The redox reaction is as follow:
MnO₂ + 4H⁺ + 2Cl⁻ → Mn²⁺ + 2H₂O + Cl₂
One should know the following terms,
Reducing agent:
An atom or element which tends to lose electron during a chemical reaction and get itself oxidized. In above reaction Cl⁻ is reducing agent as it carries a negative charge (means it has one extra electron) on the reactant side while, it has zero oxidation state on the product side. It means going from -1 to 0 the Cl lost one electron hence, it is an reducing agent according to definition.
Oxidizing Agent:
On the other hand oxidizing agent is an element or compound which tends to accepts electron(s) and get itself reduced. In above reaction Mn has an oxidation state of +4 on reactant side and after gaining electron from Cl it has changed to +2 on the product side. Hence, it has reduced but has oxidized the Cl atom so it is an oxidizing agent according to definition.
