I need help understanding a post lab question for a rates of reaction lab, im a student it asks: Why was it necessary that the two solutions to be mixed at the same temperature before mixing? What error would have been introduced if the solutions were not at the same temperature (they couldnt be more than 1 degree apart when temp was measured before mixing)?

__C₅H₁₂ + __O₂ --> __H₂O + __CO₂ To balance the attached reaction, what coefficient needs to be put in front of the H₂O?

30jud to 28AM basu mw 5. Sodium carbonate is a reagent that may be used to standardize acids in the same way that you have used KHP in this experiment. In such a standardization it was found that a 0.498-g sample of sodium carbon- ate required 23.5 mL of a sulfuric acid solution to reach the end point for the reaction.

How do precipitation reactions work?
