Answer:

B.  Cl.

Explanation:

These are Group  7 elements whose reactivity reduces as you go down the group. Chlorine  has a smaller atoms than the rest and has a stronger  tendency to grab an electron in its valency shell. This is because its nucleus is closer to the outer electrons than the other elements.

Can anyone help me with the calculations for the Frequency, Wavelength, Energy Chart?
sergeinik [125]
Use the following equations to fill the chart.

E = hf
where
h = 6.63 x 10⁻³⁴ J/s, Planck's constant
f = frequency Hz
E = quanta of energy, J

c = fλ
where
c = 3 x 10⁸ m/s, the velocity of light
λ = wavelength, m

If energy is given in J/mmol, divide by Avogadro's number, N = 6.02 x 10²³, to convert it to J.

The completed table is shown below.

For the homogeneous solution, consisting of kcl and h2o, indicate the type of forces that are involved.
zubka84 [21]
<span>The pairs of substances I would expect to form homogeneous solutions when combined will form a homogeneous because both are polar and form dispersion forces, dipole-dipole and hydrogen bonding between the water molecules and ion-dipole forces between the K+ and Cl- ions and the water molecules.</span>

A student pours 800.0 mL of a 3.000 molar solution of sodium hydroxide into a 2.00 liter volumetric flask and fills the flask up
hammer [34]
M1V1 = M2V2
M1 = 3.000 M
V1 = 0.8000 L
M2 = ?
V2 = 2.00 L

M2 = M1V1/V2 = (3.000 M)(0.8000 L)/(2.00 L) = 1.20 M
