1. Explain the work being done at the New Mexico Institute of Mining and Technology and why it is significant. 2. Following a bombing, what does Romero explain needs to be collected and why?
3. What type of forensic evidence was recovered during the bomb set off at the New Mexico facility on the video that was similar to the evidence obtained at the Boston bombings and how did this evidence allow researchers to connect other pieces of evidence to the same bomb?
4. Given that pressure cooker bombs can be created using information readily available online, why does Romero believe the Boston bombers had some level of experience in creating bombs?
5. Explain why scientists record explosions at the New Mexico facility?

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

c is the answer because when something is left after something evaporates that shows the chemical change.
