<span>The answer is B) Mixture. Compound is a substance with a fixed ratio of atoms, Like Fe2O3, all the pure compounds of Fe2O3 will have the same composition: 2 parts of element Fe and 3 parts of element O. Mixture is not homogeneous, this is its composition is not uniform. As you can see two different pies will have different compositions, even though you try that they are equal.</span>

The speed of sound depends on these two things:

IrinaVladis [17]

The speed of sound depends on these two things: The type of medium and the temperature of the medium; option a.

<h3>What is the speed of sound?</h3>

The speed of sound is the distance covered in meters over a given period of time.

Speed = distance/time

The speed of sound depends on the following:

temperature - the speed of sound increases with temperature
medium - the speed of sound increases with increase in density of the medium.

In conclusion, the speed of sound increases with temperature.

Some nitrogen for use in synthesizing ammonia is heated slowly, maintaining the external pressure close to the internal pressure

swat32

Answer: The work done for the given process is -2188.7 J

Explanation:

To calculate the amount of work done for an isothermal process is given by the equation:

$W=-P\Delta V=-P(V_2-V_1)$

W = amount of work done = ?

P = pressure = 50.0 atm

$V_1$ = initial volume = 542 L

$V_2$ = final volume = 974 L

Putting values in above equation, we get:

$W=-50.0atm\times (974-542)L=-21600L.atm$

To convert this into joules, we use the conversion factor:

$1L.atm=101.33J$

So, $-21600L.atm=-21600\times 101.33=-2188728J=-2188.7kJ$

The negative sign indicates the system is doing work.

Hence, the work done for the given process is -2188.7 J

How many moles of chloroform, CHCl3, are required to fill a 253-mL flask at 100.0C and 940 torr?

aalyn [17]

Answer:

relationship between four fundamental physical properties of gases: pressure PP, volume VV, number of moles nn, and the absolute temperature TT. The ideal gas constant is denoted by RR and its exact value depends on the units chosen for the other parameters. Note that the temperature is always in Kelvins (i.e., we use the absolute temperature). The relation is:

PV=nRT
