Answer: The coordination number of Cu+ is two while the coordination number of O2- is 4
Explanation:
The coordination number of an ion in a unit cell arrangement refers to the number of immediate neighboring ions of opposite charge surrounding a particular ion. In Cu2O, the charge on Cu is +1 and the charge on the oxide ion is -2. Each copper I ion is surrounded by two oxide ions while each oxide ion is surrounded by four copper I ions in each unit cell.
Answer:
Units of force.
Explanation:
Issac Newton created the laws of motion and discovered gravity.
M(H₂O) = 97,2 g.
n(H₂O) = m(H₂O) ÷ M(H₂O).
n(H₂O) = 97,2 g ÷ 18 g/mol.
n(H₂O) = 5,4 mol.
N(H₂O) = n(H₂O) · Na.
N(H₂O) = 5,4 mol · 6,023·10²³ 1/mol.
N(H₂O) = 3,25·10²⁴ molecules of water.
n - amount of substance.
Na - Avogadro number.
Answer:
The answer is 1722 e⁻
Explanation:
Let's make a rule of three:
9.708×10⁻³¹ kg is the mass of 1 e⁻
1.672 ×10⁻²⁷ kg (which is 1 p⁺), how many e⁻ does it contain.?
1.672 ×10⁻²⁷ kg / 9.708×10⁻³¹ kg
The answer is 1722 e⁻
