Answer:
B = 0.10 M of AlCl₃
Explanation:
A = 0.10 M NaCl
NaCl → Na⁺ + Cl⁻
sodium chloride dissociate into sodium and chlorine ions. The one mole of NaCl produced on mole of Na⁺ and one mole of Cl⁻, so concentration of chloride ions will be 0.10 M.
B = 0.10 M of AlCl₃
AlCl₃ → Al³⁺ + 3Cl⁻
AlCl₃ dissociate into aluminium cation and chlorine anion. one mole of AlCl₃ dissociate into one mole of Al³⁺ and three mole of Cl⁻.
so concentration of chloride ion in 0.10 M solution is
0.10 × 3 = 0.3 M
C = 0.10 M MgCl₂
MgCl₂ → Mg²⁺ + 2Cl⁻
MgCl₂ dissociate into one mole of Mg²⁺ and two mole of Cl⁻.
so concentration of chloride ions in 0.10 M solution of MgCl₂ is,
2× 0.10 M = 0.20 M
d = 0.05 M CaCl₂
CaCl₂ → Ca²⁺ + 2Cl⁻
CaCl₂ dissociate into one mole of Ca²⁺ and two mole of Cl⁻, So concentration of chloride ions in 0.05 M CaCl₂ is
2× 0.05 = 0.1 M
Answer:
B)The octet of carbon atom remains incomplete in the molecule.
Explanation:
Answer:
Explanation:
The temperature and amount of gas are constant, so we can use Boyle’s Law.
Data:
Calculations:
The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. They strike the surface of the container with more force. If the container can expand, then the volume increases until the pressure returns to its original value. I hope that helped!!
