A. CI, Br

Explanation:

Different kinds of atoms bind their valence electrons with various amounts of energy. In order to remove the valence electrons, enough energy must be available.

The amount of energy required for the removal of an electron is the ionization energy or ionization potential.

The ionization energy depends on:

  • Nuclear charge
  • Atomic radius
  • Sublevel accomodating the electron to be removed.
  • Special stability of half or fully filled sublevels.

Across a period, the ionization energy increases.

Down a group ionization energy decreases due to increasing atomic radii.

Cl and Br are in the same periodic group. Cl is element number 2 and Br is element 3 in the group of the halogens.

Therefore, Cl will have a higher ionization energy compared to Br.

Salt water contains n sodium ions (NA ) per cubic meter and n chloride ions (Cl-) per cubic meter. A battery is connected to met
IRINA_888 [86]

Answer: hello your question is incomplete below is the complete question

Salt water contains n sodium ions (Na+) per cubic meter and n chloride ions (Cl−) per cubic meter. A battery is connected to metal rods that dip into a narrow pipe full of salt water. The cross sectional area of the pipe is A. The magnitude of the drift velocity of the sodium ions is VNa​ and the magnitude of the drift velocity of the chloride ions is VCl​.

What is the magnitude of the ammeter reading ?

answer :

| I | = neAVₙₐ  + neAV (Cl-)

Explanation:

Given that there are N sodium ions

<u>Determine the Magnitude of the ammeter reading </u>

| I | = current due to sodium ions + current due to (Cl-) ions

     = neAVₙₐ  + neAV (Cl-)

How much heat is gained when a 50.32g piece of aluminum is heated from 9.0°c to 16°c
Rashid [163]

Answer: 317 joules

Explanation:

The quantity of heat energy (Q) gained by aluminium depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

In this case,

Q = ?

Mass of aluminium = 50.32g

C = 0.90J/g°C

Φ = (Final temperature - Initial temperature)

= 16°C - 9°C = 7°C

Then, Q = MCΦ

Q = 50.32g x 0.90J/g°C x 7°C

Q = 317 joules

Thus, 317 joules of heat is gained.
