B. sulfur and oxygen

Firstly, covalent bonds are made between non-metals. In covalent bonding electrons get shared between elements in order to become stable. So you answer would therefore be sulfer and oxygen (which should form sulfer dioxide).

Hope it helps!

Given the following list of densities, which materials would float in a molten vat of lead provided that they do not themselves
vampirchik [111]

Answer:

b. glass and charcoal

Explanation:

Step 1: Given data

  • Density of Pb: 11.4 g/mL
  • Density of Glass: 2.6 g/mL
  • Density of Au: 19.3 g/mL
  • Density of charcoal: 0.57 g/mL
  • Density of platinum: 21.4 g/mL

Step 2: Determine which material will float in molten lead

Density is an intrinsic property of matter. Less dense materials float in more dense materials. The materials whose density is lower than that of lead and will therefore float on it are glass and charcoal.

Phosphorus oxychloride has the chemical formula POCl3, with P as the central atom. In order to minimize formal charge, how many
Elina [12.6K]

Answer:

Phosphorus makes 5 bonds with other atoms

Explanation:

POCl_{3} has total 32 number of valence electrons (P has 5 , O has 6 and Cl has 7 valence electrons).

These valence electrons are used to draw Lewis structure of POCl_{3}.

Formal charge on an atom = (no. of valence electrons of the atom)-(no. of covalent bonds attached to the atom)-(no. of electrons in lone pair of the atom)

Applying octet rule (atoms have eight electrons in their valence shell) and minimizing formal charge of POCl_{3}, it has been found that P makes total 5 bonds with rest of the atoms.

Lewis structure of POCl_{3} along with formal charge (in parentheses) has been given below.
