Answer:
Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).
Explanation:
Non electrolytes are Pentacarbon decahydride, Phosphorus pentachloride, Glucose.
<u>Explanation:</u>
Non electrolytes do not exist as ions in aqueous solution. Since it does not get dissociated into ions, these non electrolytes do not conduct electricity when it is dissolved or it is heated or melted.
Pentacarbon decahydride is a non electrolyte.
Magnesium chloride is an electrolyte.
Copper phosphate is an electrolyte
Sulfur trioxide is an electrolyte.
Aluminum oxide is an electrolyte
Phosphorus pentachloride do not get dissociated into its ions so it is a non-electrolyte.
Glucose gets dissolved in water but do not dissociate into ions, so it is a non electrolyte.
The answer is:
C) Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.
Answer:
8.0 g
Explanation:
To convert moles to grams, you need to use the molar mass. The molar mass of sulfur is 32.06. The molar mass is the atomic mass of the atom.
(0.25 mol) × (32.06 g/mol) = 8.015 g
Round for significant figures.
8.015 g ≈ 8.0 g
