Answer:
Charging Level The cycle life of Lithium batteries can be increased by reducing the charging cut off voltage.
Explanation:
Answer:
Number of moles of Al = 0.02 mol
Number of moles of CuCl₂ = 0.02 mol
Explanation:
Given data:
Mass of CuCl₂ = 2.50 g
Moles of CuCl₂ = ?
Solution:
Formula:
Number of moles = mass / molar mass
Molar mass of CuCl₂ = 63.546 + 35.5 ×2
Molar mass of CuCl₂ = 134.546 g/mol
Now we will put the values in formula:
Number of moles = 2.50 g / 134.546 g/mol
Number of moles = 0.02 mol
Given data:
Mass of Al = 0.50 g
Moles of Al = ?
Solution:
Formula:
Number of moles = mass / molar mass
Molar mass of Al = 27 g/mol
Now we will put the values in formula:
Number of moles = 0.50 g / 27 g/mol
Number of moles = 0.02 mol

Answer:
electroluminescence is a production of light by the flow of electrons, as within certain crystals. An example is at most resataurants with a bright sign that either says open or closed.
Explanation:
Answer:
The answer to your question is pH = 9.08
Explanation:
Data
pH = ?
Concentration = 1.2 x 10⁻⁵ M
Process
1.- Calculate the pOH of the solution
Formula
pOH = -log[OH⁻]
pOH = -log[1.2 x 10⁻⁵]
pOH = 4.92
2.- Calculate the pH
Formula
pH = 14 - pOH
Substitution
pH = 14 - 4.92
Result
pH = 9.08
