Question

1)Li+?=Li2O 2)?+O2=ZnO 3)Al(OH)3=?+? 4)Fe(OH)2=?+?​

Answer 1

Ответ:

Li+O2=Li2O

Zn+O2=ZnO

Al(OH)3=Al2О3+H2O

Fe(OH)2=Fe2O3+H2O

Answer 2

1) Li+O=Li2O
2) Zn+O2=ZnO
3) Al(OH)3=Al+OH
4) Fe(OH)2=Fe+OH

Answer 3

1. Li+ + O2- = Li2O (In this reaction, one lithium ion (Li+) combines with one oxygen ion (O2-) to form lithium oxide (Li2O).)

2. 2Zn + O2 = 2ZnO (In this reaction, two zinc atoms (Zn) combine with one oxygen molecule (O2) to form zinc oxide (ZnO).)

3. 2Al(OH)3 = Al2O3 + 3H2O (In this reaction, two molecules of aluminum hydroxide (Al(OH)3) decompose to form one molecule of aluminum oxide (Al2O3) and three molecules of water (H2O).)

4. Fe(OH)2 = FeO + H2O (In this reaction, one molecule of iron(II) hydroxide (Fe(OH)2) decomposes to form one molecule of iron(II) oxide (FeO) and one molecule of water (H2O).)
