1. What is the chemical formula?NO2
2. What is the molecular geometry?Bent molecule with C2v point group symmetry
3. Why can nitrogen dioxide be dangerous?When people breathe too much of it, it can irritate the lungs and make it hard to breathe. At about 174 parts per million for one hour, it can be deadly.
4. How does nitrogen dioxide get into our homes?It can come from gas stoves that don’t have good ventilation, and from cars and power plants that release it into the air.
