Answer:
C. The samples contain the same substances in a fixed proportion.
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.
Yes, Sharpies contain volatile solvents—and when inhaled these solvents can produce a "high." The effects of inhalants (including Sharpies) can be similar to those of alcohol and include slurred speech, lack of coordination, euphoria, and dizziness.
Answer:
Lewis structure in the attached image.
Explanation:
To draw the Lewis structure of H₂SO₄, we need to consider the octet rule: atoms gain, lose or share electrons to have 8 electrons in their valence shell. Hydrogen is an exception because its valence shell is complete with 2 electrons (duet). H, S and O are nonmetals, so they form covalent bonds to complete their valence shell, that is, they share pairs of electrons.
- S has 6 valence electrons, so it has to share 2 pairs of electrons to reach the octet.
- O has 6 valence electrons, so it has to share 2 pairs of electrons to reach the octet.
- H has 1 valence electron, so it has to share 1 pair of electrons to reach the duet.
In the attached image is the resulting Lewis structure.
