explain why samples of gold and copper can have the same extensive properties, but not the same intensive properties

1 answer:

3 0

Extensive properties, as volume and mass, depend on the amount of material. So, you can have a sample of gold and a sample of copper with the same volume as long as you have different amount of each one.

On the other hand, intensive properties do not depend on the amound of material but on the chemical constitution of the material. Density is an intensive property, so gold and copper have different densities. That is why you can use intensive properties to characterize different materials.

How many atoms of hydrogen are found in the compound, NH4C2H302?

Mariulka [41]

<h2>Answer:</h2>

7 hydrogen atoms

<h2>Explanation:</h2>

N<em><u>H4</u></em>C2<em><u>H3</u></em>02

In this problem we see the hydrogen atom twice, along with the numbers 4 and 3 next to them. (as shown above in bold & underlined)

So, in order to find how many there are in all you add both hydrogen atoms together-

H4+H3= H7

therefore, there are 7 hydrogen atoms in all

Does this sound good/ right? I hope so! Thank you! please give me criticism NICELY!!

Mamont248 [21]

This sounds good so far.
May want to check how you say "and are spread way out" - a better way to say it would be "the crystals are spread out"

Dinitrogen oxide (N₂O) gas was generated from the thermal decomposition of ammonium nitrate and collected over water. The wet ga

RideAnS [48]

Answer:

126.73 mL

Explanation:

The total pressure of the gas mixture is the sum of the vapor pressure of its constituents. So, the vapor pressure of N₂O(p) can be calculated:

750 = 18.85 + p

p = 750 - 18.85

p = 731.15 torr

It means that for 731.15 torr, N₂O occupied 130 mL. For the general gas equation, we know that

$\frac{p1V1}{T1} = \frac{p2V2}{T2}$

Where <em>p</em> is the pressure, <em>V</em> is the volume, <em>T</em> is the temperature, 1 is the initial state, and 2 the final state. For the same temperatue (21ºC), the equation results on Boyle's law:

p1V1 = p2V2, so:

731.15x130 = 750xV2

750V2 = 95049.5

V2 = 126.73 mL
