Answer
3.65 liters is the volume of H₂ produced in the reaction
Explanation:
2 Al(s) + 6 HCI (aq) → 2AICI₃ (aq) + 3 H₂ (g)
I'll convert the mass of Al to moles.
2.93 g . 1mol/26.98 g = 0.108 moles
Ratio is 2:3. 2 moles of Al can produce 3 moles of H₂
Then, 0.108 moles of Al would produce (0.108 .3)/ 2 = 0.163 moles of H₂ Let's apply the Ideal Gases Law to find out the produced volume, at STP.
STP is 1 atm as pressure and 273K as T°
1 atm . V = 0.163 mol . 0.082L.atm/mol.K . 273K
V = (0.163 mol . 0.082L.atm/mol.K . 273K) / 1atm
V = 3.65 L
Answer:
C.) If the solid is conductive, the bonds are metallic.
1) 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.
2) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.
3) Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons. Most metals have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.
