1. What data is collected in a titration?
2. How would I be able to find what the volume of 0.10M HCl should be needed to titrate .136 g Na2CO3 according to the reaction equation:
Na2CO3(aqueous) +2HCl(aqueous)  2NaCl(aqueous) + H2O(liquid) + CO2(gas)
3. How would I determine the density of a solid using water displacement? Can you give me a detailed procedure with steps??
4. What is the density and specific heat (heat capacity) of aluminum, zinc and iron?
