An example of an extensive property of matter is "mass"
N76 [4]3 years ago
3 0

Answer:

Examples of extensive properties are: temperature, mass, weight, volume, lenght, force, among others.

Explanation:

Extensive properties are properties that depends on the amount of mass (thus depends on the size) of an object.

For example:

It is not the same to have a package of 1 kg of sugar than a package of 5 kg of sugar. The amount of mass is different and also the weight and the volume (the 1 kg package take less place than the package of 5 kg).

Also exists  Intensive properties, these ones do not depends on the amount of mass, such as: density, organoleptic properties, boiling point, melting point, amog others.

In the previous example, the flavor of both packages of sugar will be the same independetly of the amount of sugar.

Calculate the pH of a solution in which [OH–] = 4.5 × 10–9M.
posledela

Answer:

5.65 is the pH.

Explanation:

I am assuming that you are asking for confirmation on your answer. The answer is 5.65.

You would do:

[pOH] = -log[OH-]

          = -log[4.5*10^-9]

         equals about 8.3468

To find pH your would subtract the pOH from 14.

14-8.3468 = 5.65 << Rounded to match the answer choices.

How many moles of Al are needed to react completely with 1.2 moles of Fe0
DIA [1.3K]
0.8 moles

 3 moles of feO  gives you  2 moles of Al and 1.2 of your moles should give you 1.2 divided by 3*2 so it equals 0.80 moles 

Right?

The volume of oxygen, collected over water, is 185 mL at 25 degrees Celsius and 600 torr. calculate the dry volume of the oxygen
ivolga24 [154]

Answer:

0.1593 L.

Explanation:

  • We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

  • If n and P are constant, and have two different values of V and T:

<em>P₁V₁T₂ = P₂V₂T₁</em>

<em></em>

P₁ = 600 torr/760 = 0.789 atm, V₁ = 185.0 mL = 0.185 L, T₁ = 25.0°C + 273 = 298.0 K.

P₂ (at STP) = 1.0 atm, V₂ = ??? L, T₂ (at STP = 0.0°C) = 0.0°C + 273 = 273.0 K.

<em>∴ V₂ = P₁V₁T₂/P₂T₁</em> = (0.789 atm)(0.185 mL)(298.0 K)/(1.0 atm)(273.0 K) = <em>0.1593 L.</em>
