At 1'30'' of the video the reaction is shown taking place. Write the chemical equation of this reaction. please answer short

In any manufacturing process, reaction monitoring ensures that a chemical reaction proceeds as expected. Table 1 shows the monitoring data for the formation of chlorohexane, collected using a technique called gas chromatography. Note that the concentrations of the chlorohexane solutions are given in millimoles per litre (mmol l–1). The abbreviation mM (millimolar) is frequently used. Plot a graph of the data in Table 1. The graph should be drawn on graph paper or use fine grid if it’s drawn on Excel. Elapsed Time/Hours  Concentration of Chlorohexane/mM 0 0 2 40 4 65 6 80 8 90 10 95 12 99

Part B Before investigating the scene, the technician must dilute the luminol solution to a concentration of 8.00x102 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00 L of the diluted spray? Express your answer with the appropriate units. • View Available Hint(s) Tempjetes Symbols undo redo Teset keyboard shortcuts Help Value Units moles of luminol =

Please help me complete question 4

What should I put in the box

3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industria strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume o vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below. Volcano # 1 Volume of gas produced (mL.) vs. Time (s) for Volcano #1 Time Volume of gas (s) produced (ml) 60 E 50 10 20 30 25 8 40 38 46 30 20 Volume of gas produced (ml) 40 50 50 60 52 of 10 53 20 40 60 80 Time (s) Volcano # 2 Volume of gas Volume of gas produced…

I need help understanding how to do this, can you please show me how you get the CFU/mL

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.
