Question

te a balanced chemical equation for each reaction listed below for the group IV/V known solution. Be sure to balance each equation and include physical state notations. These reactions will be included in your Lab Report for this experiment and should also be recorded in your Lab Notebook. GROUPS IV AND V REACTIONS 1) NH + NaOH = (turns moist red litmus paper blue) 2) NH3(aq) 3) Ca?' + CO, — 4) CaCO3 + HC,H,O, — 5) Ca²+ + CO2- 6) CaC2O4 + HCI — 7) Mg?+ + Na2HPO4 + NH3 -

answer all

Answer 1

1) NH₄⁺ + NaOH $\rightarrow$ Na⁺ + NH₃ + H₂O

2) NH₃$\rightarrow$ NH₄⁺ + OH^-

3) CaCO₃

4) CaCO₃ + 2 CH₃COOH $\rightarrow$ Ca(CH₃COO)₂ + H₂O + CO₂

5) CaC₂O₄

6) CaC₂O₄ + 2 HCl $\rightarrow$ CaCl₂ + H₂C₂O₄

7) MgNH₄PO₄ + 2 Na
