Can alkali metals react with nitrogen? Of the alkali metals, only lithium reacts with nitrogen, and it forms a nitride (Li3N). In this respect it is more similar to the alkaline-earth metals than to the Group 1 metals. Lithium also forms a relatively stable hydride, whereas the other alkali metals form hydrides that are more […]

What is the movement of charge when a positively charged object is grounded out?
What is the movement of charge when a positively charged object is grounded out? Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer […]
Why is centripetal force not a force?
Why is centripetal force not a force? In a similar way, the centrifugal force has very real effects on objects in a rotating reference frame and is therefore real. But the centrifugal force is not fundamental. Rather it is caused by the rotation of the reference frame. The centrifugal force is not some psychological oddity […]
Is heat from a fire radiation or convection?
Is heat from a fire radiation or convection? The thermal radiation from the fire spreads out in all directions and is able to reach you. This thermal radiation is mostly in the form of infrared waves and visible light. In contrast, the campfire heat transferred via convection shoots straight up into the sky and never […]

What is a disadvantage of the metric system?
What is a disadvantage of the metric system? Difficult to Use With Fractions The only major disadvantage in using the metric system is that it’s not well-suited for working with fractions. For example, 1/6 meter is approximately equivalent to 167 millimeters and 1/3 kilogram is approximately equal to 333 grams. What’s better 6pt or 12pt […]
