Which of the following correctly compares periodic properties of two elements and provides an accurate explanation for that diff

erence? The first ionization energy of Al is greater than that of B because Al has a larger nuclear charge than B does. A The first ionization energy of F is greater than that of O because O has a higher electronegativity than F has. B The atomic radius of Ca is larger than that of Mg because the valence electrons in Mg experience more shielding than the valence electrons in Ca do. C The atomic radius of Cl is smaller than that of S because Cl has a larger nuclear charge than S does.

A set of headphones produces sounds that cancel out sound waves from the
Basile [38]

Answer:

C. Destructive interference

Explanation:

<em>Destructive interference</em> is when there are two waves <u>with the same frequency</u>, and the peaks of one wave (the highest points) line up with the valleys (the lowest points) of the second one.

Constructive interference would cause the sound to be louder.

Absorption and reflection are interactions that would not take into account the fact that the headphones produce sounds.

What is the pH of a solution with hydrogen ion concentration of 1 x 10^–6 M?
kakasveta [241]

Answer:

The pH of the solution is 6,00.

Explanation:

The pH indicates the acidity or basicity of a substance. pH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as:

pH = -log (H +)

pH= -log (1x10^-6)

<em>pH= 6, 00</em>

Convert 1.45 × 1024 atoms of carbon to moles of carbon.
anygoal [31]
1 mol = 6.02 * 10^23 atoms of carbon
x mol = 1.45 * 10^24 atoms of carbon

1/x =6.02*10^23 / 1.45 * 10^24

6.02 * 10^23 x = 1.45 * 10^24
x = 1.45 * 10^24 / 6.02 * 10^23
x = 2.41 mols of carbon
