1. You are working with a colleague to measure the carbonate chemistry of a set of water samples. Unfortunately your colleague is a bit sloppy, and when you look at the data, you realize there must have been some errors in the measurements. Blank cells in the table below mean your colleague didn't collect data for that species in that sample. For each sample (#1-6), EITHER explain why at least some measurements for that sample must be in error OR fill in the missing data with reasonable values. (Note: you can assume the precision of the measurements is ±1mM, so inconsistencies below that level do not necessarily indicate errors.) Sample pH [H2CO3*] (MM) [HCO3] (mM) [CO3²-] (MM) Total C (mM) 1 12.0 195 199 2 3.1 155 520 3 1000 100 1101 4 7.4 317 317 50 CO 248 248 1675 6 8.3 97 402

Give detailed Solution..don't give Handwritten answer..give correct answer

Should be 3 answers in total. Will thumbs up! Next the student conducts two different runs: In RUN 1, 10.0 mL of 5.00 M NAOH is combined with 10.0 mL of 0.010 M CO and 80.0 mL of wate In RUN 2, 20.0 mL of 5.00 M NAOH is combined with 10.0 mL of 0.010 M CO and 70.0 mL of wate The following plots were obtained for each of the runs: [crystal orange] vs time (RUN 1) In[crystal orange] vs time (RUN 1) 0.0012 0.001 -2 y--0.4463x- 7.3334 y =-0.0002x + 0.0007 R- 0.6565 R = 0.893 0.0008 4 0.0006 -6 0.0004 -8 0.0002 0.0002 -12 time (hr) time (hr) 1/[crystal orange] vs time (RUN 1) 1/[crystal orange] vs time (RUN 2) 12000 25000 10000 20000 8000 15000 6000 y = 2000x + 1000 R =1 10000 y 4000x + 1000 R =1 4000 2000 5000 time (hr) time (hr) Figure 4.

Based on the selected correct unit, what is the value of x?

i have hard time geting it stright even after I do the experiment can  u help me with the one pls Material ChemicalsSealed NO2 tubes, KSCN solution (0.002 M), acidified Fe(NO3)3 solution (0.2 M), KSCN crystals, Fe(NO3)3 crystals, KOH (concentrated (8 M)), distilled waterApparatus:Bunsen burner, ring stand, wire gauze, matches, thermometer, dropper, test tubes, glass stirring rod, beaker tongs Procedure Part A: Fill a 600 mL beaker to the 3/4 mark with water. Bring to a boil using a Bunsen burner. In another 600 mL beaker, fill to the 1/2 mark with water; add ice in order to lower the temperature to about 0°C. Note the room temperature. Observe the NO2 thoroughly at room temperature. Place the sealed NO2 tube in the cold bath. Note your observations. Remove the test tube from the cold bath. Let the test tube stand until it reaches room temperature. Note your observations. Place the test tube in the hot bath. Note your observations. Remove the test tube from the hot bath. Let the test…

can be used as a standard solution for checking the concentration of a solution containing sulphuric acid, 8.7 cm' of sulphuric acid. Find the concentration of the sulphuric acid in both mol dm3 and g dm³. In a particular experiment 10,0 cm³ of a 0.50 mol dm³ solution of sodium ethanedioate was found to react with Q2. Sodium ethanedioate, Na;C¿O4, can be made into a solution of an exact and reliable concentration and so London ndon A.C.1.2
