OSHA's Hazard Communication Standard requires chemical manufacturers to evaluate hazards relating to their products and provide a Safety Data Sheet in accordance to the Globally Harmonized System (GHS) in which the use of pictograms (see Figure 1) is required to communicate hazard information. Predict (with reasons) two (2) hazards related to each of the two activities below, and assign two (2) relevant pictograms listed in Figure 1 to each of the two activities. Activity 1: Removing diethyl ether (last opened in 2019) using a rotary evaporator. Activity 2: Using carbon monoxide gas as a reducing agent to reduce iron chloride.

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

Identify and explain the mistakes made in the following laboratory protocols: A 1250 mg sample of NaOH was weighed using an analytical balance. The pellets were directly transferred in the balance pans, pellets were gradually added until the reading of the balance was near to 0.2000 mg.
1-arr In a study of the gas phase decomposition of phosphine at 120 °C PH3(g)- →1/4 P4(g) + 3/2 H2(g) the concentration of PH3 was followed as a function of time. It was found that a graph of In[PH3] versus time in seconds gave a straight line with a slope of -2.50×10² s1 and a y-intercept of -3.24. Based on this plot, the reaction i v O order in PH, and the half life for the reaction is seconds. zero first second
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.
