What fossil occurs in the most land masses?
animals
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.
Is fossil evidence used to support continental drift hypothesis?
Yes, fossil evidence such as similar plant and animal species found on separate continents has been used to support the continental drift hypothesis. The distribution of fossils across continents suggests that these land masses were once connected and later moved apart.
Do you need to know the individual masses of the samples of water and salt in order to measure the change in mass when the two samples are mixed?
No, you do not need to know the individual masses of the samples of water and salt to measure the change in mass when they are mixed. You can simply measure the mass of the mixture before and after mixing to determine the change in mass.
When did The Masses end?
The Masses ended in 1917.
Which fossil fuel is mixture of aromatic hydrocarbons with high molar masses?
Crude oil is the fossil fuel that is a mixture of aromatic hydrocarbons with high molar masses. It is formed from the remains of ancient marine organisms that were buried and transformed over millions of years.
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 the relationship between mole fraction and mass fraction in a given mixture?
The relationship between mole fraction and mass fraction in a mixture is that the mole fraction of a component is equal to its mass fraction divided by its molar mass, multiplied by the total mass of the mixture. This relationship helps in understanding the proportion of each component in the mixture based on their masses and molar masses.
What is the mass of a saltwater mixture?
Mass is an extensive property. If you have more of the mixture, there will be more mass.
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.
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 can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of gases is inversely proportional to the square root of their molar masses. By comparing the molar masses of the two gases, you can determine which gas effuses faster. The gas with the lower molar mass will effuse more quickly.
In the mixture lab you waited to see if a liquid would form lumpy or fluffy masses which would indicate it was a?
colloid
In the Mixtures lab you waited to see if the liquid would form lumpy or fluffy masses which would indicate it was a?
heterogeneous mixture. Lumpy masses would suggest that the substances did not fully mix together, while fluffy masses would indicate a more homogeneous distribution of particles in the liquid.
How do you calculate the density of an ethanol-water mixture?
To calculate the density of an ethanol-water mixture, you would use the formula: Density (mass of ethanol mass of water) / (volume of ethanol volume of water) You would need to know the masses and volumes of both ethanol and water in the mixture. Then, you can plug these values into the formula to find the density of the mixture.
Which fossil occurs on the most land masses what this suggest about when these particular continents broke up?
The trilobite fossil is found on all continents, suggesting they were once connected in a supercontinent called Pangaea about 300 million years ago. The distribution of trilobite fossils across land masses helps support the theory of continental drift, which states that continents were once joined together before drifting apart due to tectonic plate movements.
