Across
- 1. Prevention and minimization of these types of products is important.
- 4. The amount of this used in a reaction can be lowered by choosing more efficient chemical routes.
- 7. Products should be designed with this in mind, once released into the environment they will be able to break down harmlessly.
- 8. The use of these in a reaction can lower the energy required and decrease reaction time.
- 9. The amount of waste produced can be decreased by minimizing the number of these in a reaction.
- 10. Doing this in real time, as a chemical reaction progresses, will prevent the formation of hazardous or polluting substances and waste.
- 11. Predict the properties of these to reduce their toxicity by designing chemical processes accordingly.
Down
- 2. Reduce the overall amount of these used especially those that are organic.
- 3. Renewable forms of this are more sustainable as they deplete less natural resources.
- 5. Ensuring this is high results in more reactant atoms forming products and less waste.
- 6. When designing chemical processes it is important to consider this a priority, it can be done by assessing and minimizing risks, consequentially lowering the chance of accidents occurring.
- 9. Using less dangerous chemicals in this type of reaction ensures it is less hazardous.
