Explain what effect the following scenarios would have on the calculated specific heat (i.e. would it be calculated artificially high, low, or have no effect). Your explanation should address what variable(s) would be affected by the scenario and how that affects the calculation of specific heat.(1.5pt each) A student accidently dropped the piece of metal on the countertop during the process of transferring it from the boiling water bath to the calorimeter, but was quickly picked up and put into...

Error Analysis 1. In parts A, B, and C, if the calorimeter was not dry, the change in temperature would be too (high/low). This would make the |AH| appear too _(high/low). 2. If a reaction is exothermic, the sign of AH is and heat is 3. If a reaction is endothermic, the sign of AH is and heat is 4. In the determination of the specific heat of the metal, if some of the water that was used to...

1. for each of the given situations, tell how the error will affect the calculated specific heat. Will it be too high, too low, or have no effect on the result? explain your answer. a. the balance used to determine the mass of the metal was in error by 10g on the high side. In other words, the balance gave a larger mass than the true mass. b. it was thought that the metal was in the boiling water long...

Suppose a lab scale consistently measures 2 g too high. How would that effect measurement of specific heat? Too high, too low, or not at all?
Need help with my lab report for specific heat of unknown metal
Need help with my lab report for specific heat of unknown metal! I need to Find the Specific Heat of Al! I know its Q= M x Cs x Change in Temp I am getting a such a high number am just confused if its right. Here is what I got in Lab: Aluminum Mass of Metal (Mm): 6.128g Mass of water (Mw) : 25 mL Temp of water in calorimeter: 23.6 C Temp of metal in water-bath: 100 C...

What would have happened to a calculation of the specific heat of your metal in the second trial if you had not carefully dried the metal before reuse? Clearly explain your reasoning. NG 3 3. What would have been the effect on your calculation of the specific heat of the metal had you forgotten to add the correction for your calorimeter constant? Explain. 4. How would your data have been affected if you had failed to dry your calorimeter between...

Post Laboratory Questions 1. A student places 138 g of an unknown metal at 99.9°C into 60.00 g of water at 22.2 °C. The entire system reaches a uniform temperature of 31.5 °C. Calculate the specific heat capacity of the metal. 2. If the correct specific heat of the metal in problem 1 is 0.25 J/gºC, calculate the percent crror. 3. While transferring the piece of unknown metal to the calorimeter, the student dropped the metal into the...

In a lab experiment involving calorimetry with brass and lead samples, a perfect calorimeter with no heat loss in which any heat lost from the metal was gained by the water was assumed. If the calorimeter was not perfect and some heat was lost to the environment, would this cause your calculated specific heat capacity of a solid (c) values to be higher or lower than the actual specific heat capacity of a solid (c) values?
