Answer:
1) Test tube 3, and 1.
2) Test tube 4, and 2.
3) Test tube 3.
4) Test tube 1.
Explanation:
Test tubes 4, and 2 don't react because the sodium carbonate (NaCO3) needs to become sodium hydrogen carbon (NaHCO3) to form a possible reaction. NaCO3 + C6H8O7 → No reaction.
NaHCO3 + C6H8O7 → NaC6H7O7 + H2O + CO2
Answer:
isotopes of hydrogen are protium,deuterium and tritium
1.) Calculate the change in pH when 4.00 ml of 0.100 M HCl(aq) is added to 0.100 mL of a buffer solution that is 0.100 M in NH3 (aq) and 0.1000 M in NH4Cl(aq).
2.) Calculate the change in pH when 4.00 mL of 0.100 M in NaOH(aq) is added to the original buffer solution.
Answer:
iron (III) oxide =Fe2O3
iron(III) carbonate =Fe2(CO3)3
