Aluminum hydroxide is insoluble in pure water but dissolves in a solution of sodium hydroxide because: Select the correct answer

below: hydroxide ions neutralize the Al3 ion, a Lewis acid aluminum participates in an acid-base reaction in the presence of sodium hydroxide the excess of hydroxide ions pushes the equilibrium toward further dissolution of Al(OH)3 aluminum forms a complex ion with excess hydroxide

Answer:

aluminum forms a complex ion with excess hydroxide

Explanation:

Complex formation accounts for the dissolution of certain compounds. For instance,reaction of aluminum and sodium hydroxide yields insoluble aluminum hydroxide as follows;

Al(s) + 3NaOH(aq) -----> Al(OH)3(s) +Na(s)

However, in excess NaOH, the solid aluminum hydroxide dissolves as due to the formation of a complex Al(OH)4^- in the solution.

What is the product when magnesium reacts with nitrogen? Mg(s) + N2(g) → Mg2N3(s) Mg3N(s) Mg3N2(s) MgN3(s)
bixtya [17]
Look at the periodic table to find the charge on atoms.
 Magnesium is +2 and Nitrogen is -3. Since there are two nitrogen charge 2*-3 = -6 there needs to be 3 Mg then (3*2+ = 6+) to pair with the two nitrogen.
3 Mg(+2) + 2 N(-3) = Mg3N2

calculate the heat required in joules to convert 18.0 grams of water ice at a temperature of -20 c to liquid water at the normal
KIM [24]

Answer:

Explanation:

Heat required to convert ice to ice at 0⁰C

= mass x specific heat x rise in temperature

= 18 x 2.09 x 20

= 752.4 J .

heat required to convert ice at 0⁰C to water at 0⁰C

mass x latent heat of fusion

= 18 x 336

= 6048 J

Heat required to increase the temperature of water to 100⁰C

= 18 x 4.2 x 100

= 7560 J

Total heat required

7560 + 6048 + 752.4

= 14360.4 J
