Answer: Option (c) is the correct answer.

Explanation:

Number of moles is defined as given mass of substance divided by molar mass.

Mathematically,    No. of moles = \frac{mass of given substance}{molar mass}

Molar mass of H_{2}O_{2} is 34.015 g/mol.

Therefore, calculate number of moles of H_{2}O_{2} as follows.

       No. of moles = \frac{mass of given substance}{molar mass}

                             = \frac{17.0 g}{34.015 g/mol}

                             = 0.4997 mol

or,                          = 0.500 mol (approx)

Thus, we can conclude that 0.500 mol is present in 17.0 grams of H_{2}O_{2}.

The electron configuration of an element is 1s22s22p4. Describe what most likely happens when two atoms of this element move tow
Vlad1618 [11]

Answer:

When the two atoms move towards each other a compound is formed by sharing electron pairs supplied by each of the atoms to enable them have the stable 8 (octet) valency electrons in their outermost shell

Explanation:

The electronic configuration of the given element can be written as follows;

1s²2s²2p⁴

The given electronic configuration is equivalent to that of oxygen, therefore, we have;

The number of electrons in the valence shell = 2 + 4 = 6 electrons

Therefore, each atom requires 2 electrons to complete its 8 (octet) electrons in the outermost shell

When the two atoms move towards each other, they react and combine to form a compound by sharing 4 electrons, 2 from each atom, such that each atom can have an extra 2 electrons in its outermost orbit in the newly formed compound and the stable octet configuration is attained by each of the atoms in the newly formed compound.
