Answer:

Keq for this reaction is 6.94x10⁻³

Explanation:

The equilibrium equation is this one:

N₂O₄ (g) ⇄  2NO₂ (g)

Initially we have 0.03 moles from the dinitrogen tetroxide and nothing from the dioxide.

In the reaction, some amount of compound (x) has reacted.

As ratio is 1:2, we have double x in products.

Finally in equilibrium we have:

       N₂O₄ (g) ⇄  2NO₂ (g)

       0.03 - x          2x

And we know [N₂O₄] in equilibrium so:

0.03 - x = 0.0236

x = 0.03 - 0.0236 → 6.4x10⁻³

As this is the amount that has reacted, in equilibrium I have produced:

6.4x10⁻³  .2 = 0.0128 moles of NO₂

This is the expression for K,

[NO₂] ² / [N₂O₄]

0.0128² / 0.0236 = 6.94x10⁻³

How did the development of the earliest idea about atoms differ from the later work of scientists?
gtnhenbr [62]

The correct answer is C. It was based on the thoughts of an early philosopher.

Explanation:

An atom is a basic and smallest unit that composes matter and that determine the properties of elements. Regarding the development of ideas related to atoms these did not begin in science but in philosophy; indeed the first person that proposed matter or elements were composed of certain smaller units was the philosophers Leucippus and his pupil Democritus in Ancient Greece, who stated atoms were eternal, infinite and defined the qualities of an object, idea that was supported by other Greek philosophers. But it was not until 16th and 17th centuries after the Middle Ages that the term re-emerged and until the 19th century it was officially proposed and there were experiments by scientists that later became a theory. Therefore, the development of the earliest idea about attoms differs from later work of scientists is that the earliest idea was based on the thoughts of an early philosopher.

Scilla [17]

Answer:

0.84kg of gatorade powder

Explanation:

From the question given, we were told that 0.6kg of gatorade powder required 5 gallons of water.

To obtain the mass of gatorade needed for 7 gallons of water, we simply do the following:

0.6kg of gatorade powder required 5 gallons of water.

Therefore, xkg of gatorade powder will require 7 gallons of water i.e

xkg of gatorade powder = (0.6 x 7)/5

xkg of gatorade powder = 0.84kg

Therefore, 0.84kg of gatorade powder will be required.
