Suppose 160 mL of 8.0 M NaOH(aq) is added to 197 mL of 6.0 M HNO3(aq) to make a solution with a density of 1.1 g/mL and a specific heat of 4.1 J/gxK. If the initial temperature of both solutions is 295 K, what will be the final temperature (K)? Enter your answer as an integer. H+(aq) + OH-(aq) → H2O() ΔHo=-55.8 kJ/mol

Argumentation and Documentation Classify each substance as metallic, ionic, molecular or covalent network based on your experimental results and further observations Part I. Testing Conductivity of Substances at Room Temperature Two substances were electrically conducting solids. The only classifications for substances that conduct electricity as solids are metallic or covalent network solids. Use the malleability property of metals to determine the classification of the two substances. Part II. Testing Conductivity of Solutions...
