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?

Answers

Answer:

0.432

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

1/3 X (1.27) =0.423

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

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.
