What has more atoms, a mole of carbon or a mole of fluorine?
A mole of carbon
A mole of Florine
They have the same number of atoms
Answer:
They have the same number of atoms
Explanation:
The mole (symbol: mol) is the base unit of amount of substance.
Think of mole meaning like inch. An inch of grass is the same as an inch of a flower. Mole is the standard measuring unit of atoms.

If I am calculating the volume in pv=nrt
Then, how do I know what units it is in coz normally it would be m3 but how do I know that it's not dm3
Explanation:
If you use the SI units for P, n, R and T ( In Pa, mol, JK-1mol-1 and K respectively) you'll end up with a Volume with m3 units. So if you have others in different units first convert them into the units I mentioned above and you will definitely get the answer in m3.

how does the ribosome know the sequence of amino acids
Answer:
The ribosome contains three grooves which are sites for the tRNA. The first codon is AUG, which is called a "start codon". ... So, the tRNA that has the anti-codon sequence of UAC carrying the amino acid Met bonds to the mRNA codon. Another tRNA bonds to the next codon in the next groove with the next amino acid
tornadoes form when updrafts from thunderstorms begin to _____
First answer that is correct gets brainly
Tornadoes form when updrafts from thunderstorms begin to interact with strong wind shear and develop a rotating column of air.
Updrafts are powerful vertical currents of air that occur within thunderstorms, caused by the rapid heating of the Earth's surface and the subsequent convective process. These updrafts carry warm, moist air upward, creating a conducive environment for the formation of severe weather phenomena.
When the updrafts encounter wind shear, which is the change in wind speed and direction with height, it can lead to the development of horizontal vorticity. Wind shear creates a rotating motion within the storm, where air at different heights starts to rotate at different speeds, generating a horizontal spin.
As the updraft continues to intensify, it tilts the rotating column of air from horizontal to vertical, forming a mesocyclone. The mesocyclone is a critical component in tornado formation. It acts as a localized area of strong rotation within the storm, extending from the cloud base to the mid-levels of the atmosphere.
Under specific conditions, such as the presence of a strong updraft, a well-developed mesocyclone, and further enhancement from other atmospheric factors, the mesocyclone can contract and intensify into a tornado. The process is complex and influenced by various meteorological factors, but the interaction between updrafts, wind shear, and the development of rotation plays a fundamental role in tornado formation.

How can you improve your ability to see the indicator color change at the endpoint of a titration?.
Answer: Place a piece of white paper under the analyte flask throughout the titration
Explanation:
The end point of titration can be made easy by the use of indicators. But we have to be keenly observe for each drop from the burette because, the colour change will be sudden for a drop.
What is titration?Titration is an analytical technique used to determine the unknown concentration using a standard reagent of known concentration. The standard reagent of known concentration is called titrant and the one to be determined is called analyte.
Usually analyte is taken in a conical flask and titrant in a burette. The end point of titration is the point at which the reaction is completed in perfect stoichiometry.
In acid-base titrations, the indicators used having different colors in different pH. Hence, the indicator in the analyte will change in color when the acidity of the medium changes. We have to observe keenly for the color change because it happens for any drop.
The adding of titrant from the burette must be dropwise and thus we can get a time to notice the sudden colour change of indicator.

In an experiment trying to dissolve sugar in water, a person boils water in a pot on the stove and then puts the water and the sugar in a cup. That person times how long it takes to dissolve the sugar.
According to the concept of solubility, boiling water and then adding sugar to it will take longer time to dissolve than adding water and sugar together to boil as thermal energy requires to dissolve sugar will be less.
What is solubility?Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

A disadvantage of disposing of waste polymers through recycling is that
they must first be separated.
Recycling is the process of forming new polymers and compounds as against their disposal .
Recycling involves separating the items into various sections such as paper,
plastic , metal etc. This is because they both undergo different recycling
processes.
The disadvantage of this process is that it's time consuming and also
expensive as a great amount of time and man power is needed to
