Answer:
Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. ... The water‐conducting xylem cells provide an internal hydrophobic surface facilitating water transport as well as mechanical strength.
The molecule of sulfur dioxide has two pi and two sigma bonds and one lone pair of electrons.
<h3>What is lone pair?</h3>
- A lone pair, also known as an unshared pair or a non-bonding pair, is an unshared pair of valence electrons that are not shared with another atom in a covalent connection in chemistry.
- Atom's outermost electron shell contains lone pairs. The Lewis structure can be used to locate them.
- Due to the high electric charge of a lone pair, which results in strong electron repulsion, the bond angle between the bonding pair of electrons reduces.
- They participate in the creation of a dative relationship as well.

Answer:
Mercury
Explanation:
This is the only metal that exists as a liquid at room temperature
Answer: 40 + 2x14 + 6x16 = 164g/mole
54.3g x [1mole / 164g] = 0.331moles
355mL x 1L / 1000mL = 0.355L
molarity = 0.331moles / 0.355L =
00
