Can you please answer number 1 and show all of the steps 

### Chemistry Educational Content #### 1. Describe the Imminent Importance of "Green Chemistry" and Its Importance to Society. Green Chemistry focuses on designing products and processes that minimize the use and generation of hazardous substances. It's crucial for reducing pollution, conserving natural resources, and promoting sustainability. It also aims to lower the environmental and health impacts associated with chemical manufacturing. #### 2. Characteristics of Elements, Compounds, and Homogeneous Mixtures - **Elements:** - Pure substances consisting of only one type of atom. - Cannot be broken down into simpler substances by chemical means. - **Compounds:** - Substances formed by the chemical combination of two or more elements in fixed proportions. - Can be broken down into simpler substances by chemical means. - **Homogeneous Mixtures:** - Compositions that are uniform throughout. - The different components are not visibly distinguishable. #### 3. Classification of Substances Classify each of the following as an element, compound, or mixture: - Rain Water: Mixture - Ocean Water: Mixture - Gold: Element - Table Sugar: Compound - Milk: Mixture - Blood: Mixture - Technetium: Element - Air: Mixture - Aspirin: Compound - Urea: Compound #### 4. Calculation of Lead Content in Blood Calculate the quantity of lead (in grams) in 6.0 x 10³ g of blood if the lead content is 0.62 ppm (parts per million). \[ \text{Lead content} = \frac{0.62 \text{ grams}}{10^6 \text{ grams of blood}} \times 6.0 \times 10^3 \text{ grams of blood} \] #### 5. Characteristics of Sub-Atomic Particles - **Electron:** - **Mass:** Approximately 0.0005 atomic mass units (amu). - **Charge:** -1. - **Location:** Outside the nucleus in electron shells. - **Neutron:** - **Mass:** Approximately 1 amu. - **Charge:** 0. - **Location:** Inside the nucleus. - **Proton:** - **Mass:** Approximately 1 amu. - **Charge:** +1. - **Location:** Inside the nucleus. #### 6. Thompson Experiment vs. Rutherford
