Why are nitrogen compounds explosive?
Why are nitrogen compounds explosive? Nitro compounds are explosive because although the diatomic form of nitrogen is very stable – that is, the triple bond that holds N2 together is very strong, and therefore has a great deal of bond energy – the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and […]
Can I leave laptop plugged in all the time?
Can I leave laptop plugged in all the time? But if you’re like most people, you probably keep yours plugged in when you’re at work or home. Stop doing that.

Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat […]
Is a higher refractive index better?
Is a higher refractive index better? The higher the refractive index, the closer to the normal direction the light will travel. When passing into a medium with lower refractive index, the light will instead be refracted away from the normal, towards the surface. Which has highest refractive index water or glass? Solution. The refraction index […]

What makes a synovial joint unique?
What makes a synovial joint unique? Synovial joints allow for movement. Where the bones meet to form a synovial joint, the bones’ surfaces are covered with a thin layer of strong, smooth articular cartilage. A very thin layer of slippery, viscous joint fluid, called synovial fluid, separates and lubricates the two cartilage-covered bone surfaces. What […]
Where is the greatest resistance to airflow in the respiratory tract?
Where is the greatest resistance to airflow in the respiratory tract? bronchi What happens when airway resistance is increased? Bronchospasm, mucus plugging, and edema in the peripheral airways result in increased airway resistance and obstruction. Air trapping results in lung hyperinflation, ventilation/perfusion (V/Q) mismatch, and increased dead space ventilation. What is the normal airway resistance? […]
