Please do not round off calculations until final answer. Thank you. A student dissolves 14.4 g of potassium hydroxide (KOH)in 250. g of water in a well-insulated open cup. He then observes the temperature of the water risefrom 21.0 °C to 35.2 °C over the course of 5.3 minutes.Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction:KOH(s)K(aq) + OH (aq)You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to thecorrect number of significant digits.Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known andpublished values for this reaction.Is this reaction exothermic, endothermic, or neither?If you said the reaction was exothermic or endothermic, calculate the amount ofheat that was released or absorbed by the reaction in this case.Calculate the reaction enthalpy ΔΗ per mole of KOH.rxn0exothermicendothermicneitherkJkJmol0x10X5

Q Search for 20 minutes. Then return, put it down, and weigh yourself immediately three times. Since reporting your weight is a little too personal, I want you to tell me the variation between each reading (called a first derivative measurement). You should see the first weight is somewhat higher than the rest; often as much as 2-3 pounds. What do you th this tells you about your scale's quality? All other data is provided in the lab procedure Questions So, go ahead and answer them, then. a For measuring the block, (part 1) measure something and tell me what it is. Today, definitions. Here are your lab questions: 1. Define significant figure 2. Define accuracy 3. Define precision 4. How many significant figures are present in the measurement 0.053402 mm? How many are in 0.053400? Calculate the following: For three replicate (repeated) measurements, your values are as follows: 3.510 g; 3.565 g; 3.593 Answer the following questions: a.
