What do molecules in a bowl of hot soup do?
A. Disperse
B. Evaporate
C. Vibrate
D. Sublimate
Submit
Answer:
Explanation:
i would say not d im not fully sure but id say c
When molecules present in a bowl of hot soup then they do vibration due to high kinetic energy.
What are molecules?Molecules are the example of chain substance, which can be prepared by the addition of two or more than 2 atoms of same or different nature.
In a hot soup bowl, kinetic energy of the molecules present in that soup increases due to which they move with higher velocity and also shows vibration in their mean position.
Hence, option (C) is correct i.e. vibrate.

If gas is truly to be classified as a form of matter this means it can be measured. What form of gas can be measured?
Answer:
Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).
Answer:
A dry gas, that is a natural gas, is the form in which gas can be measured.
And gas is measured in cubic meter, that is, it's volume is measured and the size of gas can be determined.

Answer:
Yes
Explanation:The structure of XeF4 is square planar.
In all the examples in the simulation, are atoms conserved?
Atoms are conversed in a Chemical reaction.
What is a Chemical reaction ?A chemical reaction is a process in which chemical bonds between atoms to break and reorganize, to form other new substances. In chemical reaction matter cannot be created or destroyed. It is called the law of conservation of mass.
Thus from the above conclusion we can say that Atoms are conversed in a Chemical reaction.

Three rocks are rolling down a hill at the same speed. Rock 1 has a mass of 1 kg1 kg; rock 2 has a mass of 1.5 kg1.5 kg, and rock 3 has a mass of 3 kg3 kg. Which rock has the most kinetic energy?
Answer: The first one has the most kinetic energy. Why? traveling with the slowest speed comes with the faster stop withholding more energy in the stone
Explanation:
What is extrapolation?
A. Predicting data that fall beyond a known data point
B. Estimating data that fall between two known data points
C. Finding a line that follows closely to all the points
O D. A close relationship between two events
Answer:
A. Predicting data that fall beyond a known data point
Explanation:
Extrapolating is unreliable because you are predicting data outside of the data range - anything could happen for the data to stop following the trend or pattern

How many molecules are present in 40g of c02
Answer:
2.258x 10 above 24 molecules
Explanation:
We use Avogadro's number of 6.022×1023 molecules per mole to calculate the number of molecules from the number of moles represented by 165 g of carbon dioxide.
The gram-molecular weight of carbon dioxide can be calculated from the atomic weights for carbon and oxygen (two of them in CO2) given in a Periodic Table of the Elements.
165 g CO244.01 g/mol×6.022×1023moleculesmol
=2.258×1024molecules

Explanation:
with examples of amino acids, explain the type of isomerism that exists in amino acids.
Answer:
All amino acids are stereoisomers with the exception of glycine (because it has no chiral centers) and the two types are enantiomers and diastereomers
Explanation:
Not sure how in depth you need but the most fundamental categories are:
Enantiomers: non superimposable images which means that they cannot be placed on top of one another and look perfectly identical and instead are structurally the same but flipped in the opposite direction. An example being D-alanine and L-alanine.
Diastereomers: The molecules are superimposable which means they have an identical structure that will look the same placed on top of one another however, the compounds attached to the structure are placed in different orders an example being, L-isoleucine and D-allo-isoleucine (compounds in same place but isoleucine has two hydrogens positioned forward while allo-iso have one positioned forward and one positioned in the back)
The common type of isomerism among amino acids is the optical isomerism.
Isomerism refers to a situation in which there are two or more compounds that have the same molecular formula but different structural formulas. When two compounds have the same molecular formula but different atom to atom connectivity, they are called stereoisomers. Stereoisomers that are mirror images of each other are called enantiomers.
The common type of isomerism among amino acids is the optical isomerism. The optical isomers of alanine are shown in the image attached.
