What do silver nitrate and magnesium do together? I need to write a lab about the chemical reaction and explain pretty much everything. The lab is due tomorrow morning. Suggestions? I also need help with these, if you can help me (just further explanation would be nice). Everywhere I look on the internet it shows help on how to make them balanced, but I don't need help with that! I need help with observations and why those observations take place.
Magnesium and hydrochloric acid
Mg (s) + 2HCl (aq) à H2 (g) + MgCl2 (aq)
Magnesium and silver nitrate
Mg (s) + 2AgNO3 (aq) à2Ag (s) + Mg(NO3)2
Silver nitrate and sodium chloride
AgNO3 (aq)+ NaCl (aq) à AgCl (s) + NaNo3
Sodium hydroxide and iron (III) nitrate
NaOH (aq) + Fe(NO3)3 (aq)àFe(OH)3 (s) + 3NaNO3 (aq)
Sodium bicarbonate decomposition
2 NaHCO3(s) à CO2(g) + H2O(g) + Na2CO3(s)
Sodium hydroxide and cobalt (III) chloride
CoCl3 (s) + NaOH (aq) à Co(OH)3 + 3NaCl
Lead nitrate and potassium iodide
Pb(NO3)2 (aq) + 2KI (aq) à 2KNO3 (aq) + PbI2 (s)
Isopropyl alcohol and oxygen
2C3H8O (aq) + 9O2 (g)à 6CO2 (g)+ 8H2O (aq)
I think you need to write a formal lab report on various types of chemical reactions.
The report may be divided into several sections like the objective, introduction, observations (perceptible changes occurring there), balanced equations, type of the reaction, discussions as to why such results come out, and conclusion (which is basically restating the hypothesis, hence proved). Objectives include simple statements examining a variety of reactions like precipitation, acid-base, gas forming, and oxidation-reduction reactions. Identify the products formed in these reactions and write balanced chemical equations and net ionic equations. A few words of introduction run like this: A chemical equation summarizes what occurs in a chemical reaction. There are various types of chemical reaction. For example, the reaction of magnesium with hydrochloric acid produces gaseous hydrogen and magnesium chloride. The balanced chemical equation is:
Mg (s) + 2HCl (aq) →H_2 (g) + MgCl_2 (aq)
Similarly, short dewscriptions are needed for all other reactions also:
Magnesium and silver nitrate Mg (s) + 2AgNO_3 (aq)→2Ag (s) + Mg(NO_3 )_2 Silver nitrate and sodium chloride AgNO_3 (aq)+ NaCl (aq) →AgCl (s) + NaNO_3 Sodium hydroxide and iron (III) nitrate NaOH (aq) + Fe(NO_3 )_3 (aq)→Fe(OH)_3 (s) + 3NaNO_3 (aq) Sodium bicarbonate decomposition 2 NaHCO_3 (s) → CO_2 (g) + H_2 O(g) + Na_2 CO_3 (s) Sodium hydroxide and cobalt (III) chloride CoCl_3 (s) + NaOH (aq) →Co(OH)_3 + 3NaCl Lead nitrate and potassium iodide Pb(NO_3 )_2 (aq) + 2KI (aq) →2KNO_3 (aq) + PbI_2 (s) Isopropyl alcohol and oxygen 2C_3 H_8 O (aq) + 9O_2 (g)→6CO_2 (g)+ 8H_2 O (aq)
The discussion portion emphasizes the theoretical basis of the reactions, like why such reactions occur in the way they do. A sample is: Magnesium is a highly active metal which liberates hydrogen from dilute acids, or even water. This reaction may be classified as a redox reaction too, where magnesium is the reducing agent which reduces H+ ions into elemental hydrogen, itself being oxidized into magnesium chloride.
Finally, a sample conclusion goes like this: Thus various types of chemical reactions were studied and found to produce a wide range of observations like gas-formation, precipitation, color-reaction, solubilisation, generation of heat, light etc.
