Answer:
Copper
Explanation:
Within intermolecular forces, ion-dipole is the strongest, followed by hydrogen bonding, then dipole-dipole, and then London dispersion.
Answer:
1.The electrode on the right is positive
2. 0.058V
Explanation:
The above cell is a concentration cell.
A concentration cell is an electrolytic cell that is made of two half-cells with the same electrodes, but differs in concentrations of the solutions. A concentration cell functions by diluting the more concentrated solution and concentrating the more dilute solution, creating a voltage as the cell reaches an equilibrium thereby transferring the electrons from the cell with the lower concentration to the cell with the higher concentration.
In the above cell, electrons flow from the left electrode (less concentrated) to the right electrode (more concentrated). Therefore, the right electrode is the positive electrode (cathode).
Part 2: Please, see the attachment below for the calculations.
Answer:
Mass = 2.222 g
Explanation:
Given data:
Volume of neon gas = 2.56 L
Temperature = 273 K
Pressure = 1 atm
Mass of neon gas = ?
Solution:
PV = nRT
n = PV / RT
n = 1 atm × 2.56 L/ 0.0821 atm. L / mol. K× 273 K
n = 2.56 L.atm / 22.4 atm. L/ mol
n = 0.11 mol
Mass = number of moles × molar mass
Mass = 0.11 mol × 20.2 g/mol
Mass = 2.222 g
A. Atoms B and D are isotopes.
b. Isotopes are elements with the same amount of protons (thus being the same element) and have different amounts of neutrons. Since atoms B and D have the same amount of protons but different amounts of neutrons, they are isotopes.
I believe the answer is that It's a gas-liquid solute-solvent combination. Hope this helps. Sorry if I'm wrong.
