Redox reaction definition
Answers
A redox reaction involves the transfer of electrons between two chemical compounds. It has an oxidizing and reducing reaction with a reducing and oxidizing reagent respectively. Oxidation is the loss of electrons while reduction is the gain of electrons.

Answer:
The correct option is C
Explanation:
A battery is an electrochemical device that converts chemical energy into electrical energy. Electrochemical device contains two electrodes (anode and cathode). These two electrodes are placed in contact with an electrolyte. A spontaneous chemical reaction (redox reaction) causes electrical energy/current to be produced. This chemical reaction causes a potential difference (which produces electric current/charge). However, this charge/electric current causes a voltage difference.

There are approximately of silver in the 100 mL silver bar.
To determine the number of atoms in a silver bar, you can follow these steps:
Calculate the mass of the silver bar:
Mass (g) = Volume (mL) x Density (g/mL)
Mass = 100 mL x 10.5 g/mL = 1050 g
Calculate the molar mass of silver (Ag):
The molar mass of silver (Ag) is approximately 107.87 g/mol.
Calculate the number of moles of silver in the bar:
Moles = Mass (g) / Molar Mass (g/mol)
Moles = 1050 g / 107.87 g/mol ≈ 9.73 moles
Calculate Avogadro's number:
Avogadro's number is approximately
Calculate the number of silver atoms in the bar:
Number of atoms = Moles x Avogadro's number
Number of atoms =
Thus, there are approximately of silver in the 100 mL silver bar.

1050 g silver * ( 1 mol silver/107.8682g) = 9.734 mol silver
9.734 moles silver * 6.022E23 atoms/ mole = 5.861E24 atoms of silver
Where molar mass if silver = 107.8682g/mol
Avogadro's number = 6.022E23 atoms/moles

Answer: The water is highly corrosive when the saturation index < - 0.5 and
> 0.5
Explanation:
If the saturation index for a pool measures the balance between the acid level and the amount of minerals in pool water. Considering its balanced water has an index value of 0.
The water is highly corrosive when the saturation index < - 0.5 and
> 0.5
The attachment below shows the calculations.
