Heat Capacity of Sodium Hydroxide

Abstract: The sea captain aspire of this experiment was to combine atomic number 20 Oxide and Water to attempt to replicate the self- wakening tush and record the temperatures achieved, that on commencement of the experiment it was spy that there was an wrongdoing with either the chemicals or the set-up procedure as no rouseing was generated. Instead, the experiment was slightly altered with new(a) chemicals. The purpose of the new experiment was to experimentally determine the Specific take fire dexterity of sodium hydroxide and also to determine which ratio of Sodium Hydroxide to Water will produce the or so warmth. It was hypothesised that the perfect concentration would be 7.5g of NaOH to 112.5g of H2O and that this reaction would stint between 50-60oC. The experiment was carried out by placing 112.5g of water into a outstanding beaker and then adding the divergent amounts of NaOH and recording the heat minded(p) off. The atomic number 42 experiment was co mpleted by using the above set-up with the surpass amount of NaOH and then placing a smaller beaker with 25ml of water privileged the larger beaker and recording the heat transferred. The results showed that out of four different amounts of NaOH, the highest amount (7.5g) produced the most heat, the original predictions were correct; the highest temperature achieved by 7.5g of NaOH was 52.04oC.

initiation: Self Heating tidy sum A self-heating can is an enhancement of the general food can. Self-heating cans nonplus dual chambers, one surrounding the other. In one version, the interior(a) chamber holds the f ood or drink, and the outside chamber house! s chemicals that brook an exothermic reaction when combined. When the user wants to heat the contents of the can, they institutionalise a ring on the can that ceases the barrier separating the chemicals in the outermost chamber. In another type, the chemicals be in the versed chamber and the beverage surrounds it in the outer chamber. When the user wants to heat the contents of the can, they push on the furnish of the can to break the barrier...If you want to get a encompassing essay, order it on our website: BestEssayCheap.com
