Answer:

She can conclude that the reaction started with three nitrogen atoms because she can be based in the law of conservation of matter which states that the amount of matter in a system is conserved: there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.

Explanation:

In science, a law is a general statement that explains a large number of observations. One law that provides the foundation for understanding in chemistry is the law of conservation of matter: it states that in any given system that is closed to the transfer of matter (in and out), the amount of matter in the system stays constant, or in other words, the amount of matter in a system is conserved.

So, in this case, for Marcia to conclude that the reaction started with three nitrogen atoms, she can be based in the law of conservation of matter, and because the matter of that system is conserved, there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.

Answer:

There would have to be three nitrogen atoms in the products. The law of conservation of matter states that the amount of substance before a reaction occurs should be the same as the amount of substance after the reaction.

How did the asteroid that smashed into Yucatan, Mexico 66 million years ago kill so many organisms (including the non-avian dino
Bad White [126]

Explanation:

Dinosaurs are living organisms that depends on the environment for survival. As the asteroid hits the Yucatan Peninsula area about 66 million years a couple of things can happen:

Frictional heating of the surface as the earth collided with the asteroid. This heating will cause surface temperature to rise globally and can induce the phenomenon of global warming. This can lead to release of water from reservoirs on the earth surface and hence flooding.

The impact can lead to increase in surface pressure beyond normal and that which life has adjusted to.

Debris in form of dust will be released into the atmosphere and a global air pollution will occur. Gases useful for life will be highly polluted by the vast amount of dusts and other particles discharged into the atmosphere.
