QUICK!! 2NaN3 —> 2Na + 3N2

this equation is balanced, but why does the N in the reactant have a subscript of 3, and the N in the product has a subscript of 2.

why did the subscript change? from what i learnt, when you balance an equation, you can only use coefficients to balance the equation.

Answers

Answer:

-Before balancing the equation, you need to determine the index of the components in the substances correctly to balance

-Between two atoms in the molecule N2 forms a stable triple bond, so nitrogen gas is denoted N2.

give reason : Inert gas shows least reactivity
pls help

Answers

Answer:

Noble gases also known as inert gases are the least reactive of all known elements because with eight valence electrons, their outer energy levels are full. As a result, noble gases cannot become more stable by reacting with other elements and gaining or losing valence electrons. Therefore, noble gases are rarely involved in chemical reactions and almost never form compounds with other elements.

Explanation:

The only exception is helium, which has just two electrons. But helium also has a full outer energy level, because its only energy level (energy level 1) can hold a maximum of two electrons. A full outer energy level is the most stable arrangement of electrons.

Explanation:

The temperature of the ideal gas in the container shown is 300K. The gas occupies a volume of 1.27. What would be the volume of the gas if it’s temperature were decreased to 100K?

At 100K the particles are moving 1/3 as fast as 300K so the volume would be

history of atomic structure​

Answers

Matter is composed of indivisible building blocks. This idea was recorded as early as the fifth century BCE by Leucippus and Democritus. The Greeks called these particles atomos, meaning indivisible, and the modern word “atom” is derived from this term. Democritus proposed that different types and combinations of these particles were responsible for the various forms of matter. However, these ideas were largely ignored at the time, as most philosophers favored the Aristotelian perspective.
