I need help with my homework

researchers working in a chemistry lab were examined anatomical structures of the brain using concentrated formaldehyde solutions. Once their studies concluded there remained 1.5 gallons of the substance and the researcher decided to pour this down the drain. In this case, they directly violet regulations put in place by which office?1. Office of research integrity 2. Institutional animal care and use committee3. Occupational safety and health administration 4. Institutional review board

1. You have determined the mp of pure Urea and pure Cinnamic acid. Here is your actual data: Urea: mp 132.5C-133.0 °C Cinnamic acid: mp 132.5C-133.0 °C 2. You have determined the mp of mixtures of urea and cinnamic acid. Here is your actual data: 1:4 (20% and 80%) urea/cinnamic acid: mp 104.5-114.6°C 1:1 (50% each) urea/cinnamic acid: mp 103.0-109.4°C 4:1 (80% and 20%) urea/cinnamic acid: mp 113.5-126.9°C In the data section of your report present your data in tabular format. Use your data (mp of Urea, cinnamic acid, and mp of the three mixtures) to construct a melting point (on the Y-axis) versus composition (% composition on the X-axis) diagram, like the one on the left below, in your report. Do not include the mp of your unknown (a common student mistake)

Determine the compound (name or structure) from the data. Explain features from each data. Molecular formula: C3H8O

Why is the glucose assay one of the most common analytical test performed in clinical chemistry.
