During chemical weathering, forsterite is dissolved by the carbonic acid in rainwater. The weathering reaction is: Mg2SiO4 forsterite + 4H2CO3 (aq) ? 2Mg2+ + 4HCO3- + H4SiO4 (aq) Use the thermodynamic data from Appendix II, source 2, for the following calculations. 4a. Calculate the Keq for this weathering reaction at 25 �C. 4b. If the reaction is at equilibrium, using Le Cha?telier�s principle, predict what would happen if Mg2+ ions were added to the solution 4c. Using Le Cha?telier�s principle,...

Two catalysts in a batch chemical process, are being compared for their effect on the output of the process reaction.

Two catalysts in a batch chemical process, are being compared for their effect on the output of the process reaction. A sample of 12 batches was prepared using catalyst 1, and a sample of 10 batches was prepared using catalyst 2. The 12 batches for which catalyst 1 was used in the reaction gave an average yield of 85 with a sample standard deviation of 4, and the 10 batches for which catalyst 2 was used gave an average yield...

LAB Reaction Rates Objectives • Evaluate the effect of concentration on the rate of a chemical reaction. ν • Examine the effect of temperature on the rate of a chemical reaction. Background: Many people believe that you cannot perform chemical reactions without expensive equipment or costly chemicals. But this isn’t true; chemical reactions happen everywhere. All you need is a food store to find many substances that can produce exciting chemical reactions. Preparation Materials water vinegar solution baking soda balloons...

Two catalysts in a batch chemical process, are being considered for their effect on the output of a process reaction. Based on literature, data with different samples with catalyst 1 were found to result to the following yield: 78.53 78.17 81.05 81.77 78.13 81.24 81.84 79.63 78.59 79.74 79.84 On the other hand, you found the following for the yield using catalyst 2: 82.05 81.57 81.71 81.29 81.79 81.47 81.75 81.50 81.75 If you can assume that the distribution characterizing...

For each chemical reaction or physical change, record your observations (i.e. color changes, a ppt or solid formation, gas bubbles/odors, heat production, etc.). Observations should be detailed descriptions of WHAT you see, hear, smell, and feel. Recording a (+/–) is NOT an observation! Short Answers: 1. Zn/HCl (single displacement) OBSERVATIONS: 2. NaHCO3/HCl (double displacement) OBSERVATIONS: 3. Sugar (C12H22O11) (decomposition) OBSERVATIONS: 4.CuSO4•5H2O (decomposition) OBSERVATIONS: 5. Fe/CuSO4 (single displacement) OBSERVATIONS: 6. NH3/HCl (combination) OBSERVATIONS: 7. Cu/HCl and Al/HCl (single displacement) OBSERVATIONS (for...
