Answer 2

Equations of Reactions:

1) NH2-CH2-COOH + Li2CO3 → NH2-CH2-COOLi + H2O + CO2 2) NH2-CH2-COOH + H2SO4 → (NH3-CH2-COO)SO4 3) CH3COOH + Mg → CH3COOMg + H2 4) CH3COOH + NaOH → CH3COONa + H2 5) C2H5OH + K → C2H5OK + H2 6) C2H5OH + 4 O2 → 2 CO2 + 3 H2O

Let's break down each reaction and write the balanced chemical equations.

1) NH2-CH2-COOH + Li2CO3 → NH2-CH2-COOLi + H2O + CO2 - The reaction involves the reaction between NH2-CH2-COOH (glycine) and Li2CO3 (lithium carbonate). - The products formed are NH2-CH2-COOLi (lithium glycinate), H2O (water), and CO2 (carbon dioxide).

2) NH2-CH2-COOH + H2SO4 → (NH3-CH2-COO)SO4 - The reaction involves the reaction between NH2-CH2-COOH (glycine) and H2SO4 (sulfuric acid). - The product formed is (NH3-CH2-COO)SO4 (glycine sulfate).

3) CH3COOH + Mg → CH3COOMg + H2 - The reaction involves the reaction between CH3COOH (acetic acid) and Mg (magnesium). - The products formed are CH3COOMg (magnesium acetate) and H2 (hydrogen gas).

4) CH3COOH + NaOH → CH3COONa + H2 - The reaction involves the reaction between CH3COOH (acetic acid) and NaOH (sodium hydroxide). - The products formed are CH3COONa (sodium acetate) and H2 (hydrogen gas).

5) C2H5OH + K → C2H5OK + H2 - The reaction involves the reaction between C2H5OH (ethanol) and K (potassium). - The products formed are C2H5OK (potassium ethoxide) and H2 (hydrogen gas).

6) C2H5OH + 4 O2 → 2 CO2 + 3 H2O - The reaction involves the combustion of C2H5OH (ethanol) in the presence of oxygen (O2). - The products formed are 2 CO2 (carbon dioxide) and 3 H2O (water).

Please note that the above equations are balanced chemical equations, representing the reactants and products in a stoichiometrically balanced manner.
