Answer:
Thats the solution to the question
The exterior of magnesium metal is shielded with a thin layer of oxide that somewhat protects the metal from attack by air. Magnesium metal burns in air with a distinctive blinding bright white spark when ignited to give a mixture of white magnesium oxide, MgO, and magnesium nitride, Mg3N2. Magnesium is highly reactive to halogens such as chlorine, Cl2 or bromine, Br2, and it burns to create dihalides magnesium chloride, MgCl2 and magnesium bromide.
Answer:
Al + 2 KOH + 6 H 2O → 3 H 2 + 2 K[Al(OH) 4] This is a complexation reaction: K[Al(OH) 4] is the formed complex. ; Silvery-white, malleable, ductile, odorless metal.

<u>Answer:</u> The average rate of disappearance of A is
<u>Explanation:</u>
The given chemical reaction follows:
The average rate of the reaction for disappearance of A is given as:
Or,
where,
= final concentration of A = 0.11 M
= initial concentration of A = 0.91 M
= final time = 90 minutes
= initial time = 0 minutes
Putting values in above equation, we get:
Hence, the average rate of disappearance of A is
