Consider the reaction ? Li(s) + ? N2(g) ⇀↽ ? Li3N(s).
Calculate the mass of lithium nitride
formed from 32.8366 g of nitrogen gas and
50.5021 g lithium.
Answer in units of g.

fire could start, buildings collapsing, and ash falling from the sky.

hope this .

the role of the microscope world in creating new materials .

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
