Question

a student burnt a metal A found in the form of ribbon. The ribbon burns with a dazzling flame and a white powder B is formed which is basic in nature.(i) Identify A and B. (ii) Write the balanced chemical equation. (iii) How can you test the basic nature of B? need it very urgently, last part is very important, please can anyone help me.​

Answer 1

Answer:

Hey mate here is your answer.//

Explanation:

A student burnt a metal A found in the form of ribbon. The ribbon burns with a dazzling flame and a white powder B is formed which is basic in nature:

1:Compound A is magnesium and compound B is magnedium oxide.

2:2Mg +O2-------> 2Mg0.

3:Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic bonding.

Answer 2

Answer:

Explanation:

1) A is magnesium ribbon while B is magnesium oxide.

2)   2Mg + $O_{2}$ ⇒ 2MgO

3) if MgO reacts with any acid then it will form salt and water as in neutralisation reaction .

MgO+HCl ⇒ MgC$l_{2}$ + $H_{2}$O
