Answer is: A. covalent bonds.
Insulator most likely has covalent bonds, because it must have low electrical conductivity.
1) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.
2) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.
3) Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
Answer:
27J/Kmol
Explanation:
Heat = number of moles times the Moeller heat capacity chimes the change in temperature.
^ Q = nC△T
^ C = Q/ n△T = +53J / (1mol) (299.5K - 297.5K)
^ = 26.5 (rounded to 27)
are hydrogen atoms which have lost protons
Answer:
Explanation: The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance
