The temperature of a reaction was monitored with an thermometer that is reported to have precision of 20.2 K (uniform distribution). If we used this thermometer to monitor the temperature change in a particular exothermic reaction, what is expanded uncertainty (use coverage factor k = 2) in the net temperature change for the following measurements: Temperature before reaction starts = 296.2 K Temperature after reaction is finished = 305.6 K Net temperature change = 9.4 K. Expanded uncertainty at the 95% confidence interval level (k = 2) = ? (include unit!) Answer: 0.3K

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
