How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of two gases in a mixture is inversely proportional to the square roots of their molar masses.
In the mixture lab you waited to see if a liquid would form lumpy or fluffy masses which would indicate it was a?
colloid
Do fossil fuels have a higher or lower energy content than a similar mass of nuclear fuel?
Total energy as expressed in Einsteins equation E=mc2 reveals that they are identical because the masses are identical and c is a constant. With present technology you can extract more energy from a given mass of nuclear fuels (in a nuclear reactor) than the same mass of fossil fuel in a thermoelectric generating plant.
Is lithium batteries an element mixture or compound?
Any battery must contain at least two distinct chemical substances, and there is no fixed ratio between the masses of the two substances. Therefore, any battery, including a lithium battery, is a mixture.
How many different masses of the Cl2 molecule would you expect to find in a sample of chlorine gas?
three different masses.
Which fossil fuel is a mixture of aromatic hydrocarbons with high molar masses?
coal
What fossil occurs in the most land masses?
animals
A mixture is prepared using equal masses of the two volatile liquids benzene and ethanol What is the mole fraction of benzene in this mixture?
0.371
What is a mechanical mixture?
A mechanical mixture or heterogeneous mixture is a mixture with different parts that you can see. For example an omelette is a mechanical mixture because you can see the different parts that make up the omelette.

The rate of effusion of two gases in a mixture is inversely proportional to the square roots of their molar masses.
Why is the sun the source of energy for fossil fuels?
Fossil fuels are produced by the slow alteration of masses of vegetation, compressed underground. That vegetation originally used the energy of sunlight to grow, therefore it is the sun's energy which is stored in chemical form, in fossil fuels.
What is the average mass of the mixture of an elements isotopes?
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
Why can a formula be used to represent a compound but not a mixture?
In a compound, there is always a constant ratio between the masses of any two elements contained in the compound. This is not true generally for a mixture.
What is the colloid and suspension and solution?
If a mixture settles over time and separates it is a suspension (milk with chocolate added). If a mixture does not separate overtime but forms lumpy or fluffy masses (like cottage cheese) it is a colloid. If a mixture does not separate or form lumpy masses it is a solution. Suspensions separate, colloids form lumps and may look 'cloud-like' and solutions remain the same.

How do you calculate the center of gravity?
By taking the weighted average of all the individual masses. If the masses are distributed (as opposed to point-masses), integrals must be used.By taking the weighted average of all the individual masses.

When was For the Masses created?
For the Masses was created in 1997.
