what is the charge of aluminum when paired with non metals?
Homework Answers
Aluminium is a metal when paired with non metal it posses + 3 charge
For example AlCl3
Here Al is (+3) and Cl is (-1)
AlN ( aluminium nitride)
Here Al is (+3) and Nitride is (-3)

Magnesium-aluminum alloys are commonly used in aircraft construction. When treated with acid, both metals react to form hydrogen gas, as shown in the unbalanced chemical equations below. A 1.000 g sample of alloy produces 0.107 g of H2 (g) when reacted with excess HCl (aq). What is the percent composition by mass of Al in the alloy? Al (s) + HCl (aq) à AlCl3 (aq) + H2 (g) Mg (s) + HCl (aq) à MgCl2 (aq) + H2 (g)

21. (25 points) 8-hydroxyquinoline (Q) can complex and precipitate many metals. A mixture of the aluminum and magnesium complexes weighed 1.0843 g (MW=459.43; 312.61). When ignited, the mixture decomposed and left a residue of Al2O, and MgO weighing 0.1344g. What is the wt% of the Al-complex in the mixture?
What is required for there to be a non-zero magnetic force on a charge?
QUESTION 1 What is required for there to be a non-zero magnetic force on a charge? The presence of a magnetic field The presence of a magnetic field and non-zero velocity of the charge The presence of a magnetic field and a component of (or all of) the velocity of the charge which is perpendicular to the magnetic field The presence of a magnetic field and a component of (or all of) the velocity of the charge which s parallel or antiparallel to the magnetic...

Aluminum is one of the most versatile metals. It is produced by the Hall-Heroult process, in which molten cryolite, Na_3AlF_6, is used as a solvent for the aluminum ore. Cryolite undergoes very slight decomposition with heat to produce a tiny amount of F_2, which escapes into the atmosphere above the solvent. K_c is 2 times 10^-104 at 1300 K for the reaction. Na3AlF6(/) 3 Na(/) + Al(/) + 3 F2(g) What is the concentration of F_2 over a bath of...
