1. All answers to be entered via short answer are in the NUMERICAL FORMAT and presented up to the 3rd decimal place. ADD TRAILING ZEROS if necessary, to complete your answer. NO NEED TO INCLUDE THE UNIT for now.For uniformity of answers, please be guided by the following examples:- If your answer is 5.627594, enter 5.628- If your answer is 3.129934, enter 3.130- If your answer is 8.38, enter 8.380- If your answer is 1.2, enter 1.200- If your answer is 25, enter 25.000- If your answer is less than the value of 1, always place a zero before the decimal point (E.g.: if 0.5, enter 0.500)2. In cases for answers in the EXPONENTIAL FORMAT, please be guided by the following examples and format:- Do not convert your answer to decimal format- If your answer from the calculator is 1.23454566 x 10E-4, enter 1.235x10^-4 (no spaces in between)- If your answer from the calculator is 7.379566 x 10E-5, enter 7.38x10^-5 (no spaces in between)3.

A. Types of Error. A group of students is doing an analysis of copper in a 1-peso coin. They were tasked to prepare standard solutions and weigh the analyte as the end-product of their experiment. What type of error is it and explain how this type of error incurring in their experiment. Choices for Type of Error 1. Determinate error – also known as systemic error, causes the mean of a data set todiffer from the accepted value. It can cause all the results to be too high or too low. a. Instrumental error – caused by non-ideal instrument behavior, by faultycalibrations, or by use under inappropriate conditions. Calibration eliminatesmost systematic errors. b. Method error – arise from non-ideal chemical or physical behavior of analyticalsystems. It includes the slowness of some reactions, the incompleteness ofothers, instability of some species and the possible occurrence of side reactionsthat interfere with the measurement process. c. Personal error – result from carelessness,…
