CHEM MISC Activity B.3 Relationships in Acid-Base Reactions Lab Report Answered 2024. Activity B.3 Relationships in Acid-Base Reactions Lab Report Collective Analysis A variable is a property of an object that can take on different values. The relationships between four variables were explored in experiments A (Part I) and B (Part II). The variables were VHCl (volume of hydrochloric acid), NNaOH (total number of drops of sodium hydroxide) and VH2 O (volume of water), and T (temperatur...

Hypothesis Procedure - 1. Hypothesis 2. Level of Sig 3. Subjects & Data 4. Statistical Method 5. Fail to reject/reject null Hypothesis - null research (alternative) Level of Sig - p<0.05 Statistical Method - -excel gives you R-value (pearson correlation) -find degrees of freedom (npairs-2) -find critical correlation value -finally, compare R-value (absolute value) and critical value |R|>critical value - statistically significant correlation -if R is positive it's direct/vice ...

CHEM 103 Lab experiment 4 : Thermochemistry (Portage learning) Purpose: All chemical reactions result in some heat change. Heat changes are important not only in the laboratory but also in everyday life. Procedure: We looked at a basic combustion chemical reaction of methane plus water with a combustion reaction which produced Carbon dioxide and water: CH₄ (g) + 2o2 (g) Co2(g) + 2H2O(e) ΔH= -212.8kcal (Exothemic) CaCo3 CaO + CO2 ΔH = +42.4 Kcal (Endothermic energy coming in) Reverse: ...

Chem 162 Experiment #3: Intermolecular Forces Part II: Vapor Pressure and Enthalpy of Vaporization PURPOSE (4 pts) The purpose is to measure the enthalpies of vaporazation of pentane, diethyl ether, butanone, and 2-butanol. For each of these molecules, a portion of the enthalpy of vaporization is due to dispersion forces (all molecules have dispersion forces) and the other to a polar component. In the boxes provided below, draw the structural formula for each molecule (should be drawn by h...
