Answer:
The abundance of X-100 is 75 percent, and X-104 has an abundance of 25 percent. The answers are found by solving two equations with two unknowns, which are A plus B equals 100, and 100A plus 104B equals 10,100.
The relative abundance of each isotope in nature
X-100 = 75%
X-104=25%
By dividing the total number of ions identified by the number of ions with a particular m/z m/z m/z ratio, one may determine the relative abundance for each individual ion in the sample.
How can the abundance of two isotopes be determined?
For chemistry problems involving relative abundance, use the following formula:
(M1)(x) + (M2)(1-x) = M (E)
Find the relative abundance of the isotopes if one nitrogen isotope, nitrogen-14, has a mass of 14.003 amu and another, nitrogen-15, has a mass of 15.000 amu.
Algebra can be used to find x. ...
x = 0.996

what is the strongest intermolecular force to be overcome when ethanol is converted from a liquid to a gas?
Answer:
hydrogen bonding
Explanation:
The strongest among them is hydrogen bonding, and the weakest are London dispersion forces.
The strongest intermolecular force to overcome when ethanol is converted from liquid to a gas is hydrogen bonding.
Intermolecular forces are forces that are a weaker force of attraction than intramolecular forces.
Intermolecular forces are forces between molecules and hold these molecules together.
Hydrogen bonding is an example of intermolecular forces between the OH group in the alcohol.
During the conversion of ethanol from liquid to gas state, hydrogen bonding occurs between the partial negative charge in the oxygen and the partial positive charge in the hydrogen.

What modifications would you have to make to your home if you were confined to a wheelchair?

what is the relationship between temperature and pressure pls
Answer:
When the temperature of a system goes up, the pressure also goes up, and vice versa. The relationship between pressure and temperature of a gas is stated by the Gay-Lussac's law.
Answer:
We find that temperature and pressure are linearly related, and if the temperature is on the kelvin scale, then P and T are directly proportional (again, when volume and moles of gas are held constant); if the temperature on the kelvin scale increases by a certain factor, the gas pressure increases by the same factor.

cracks in the road, hot air balloons, tire bursts
Explanation:
cracks in the road: the road expand on heating
hot air balloons: Because the hot air inside the balloon bag increases in size faster than the container it stretches the bag so that it expands and displaces the colder (heavier) air outside the bag
tire bursts in hot days when filled full of air due to thermal expansion

If 1000 ml of linseed oil has a mass of 992 g, calculate the density of linseed oil.
Answer:
0.99 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 992 g
volume = 1000 mL
We have
[tex]density = \frac{992}{1000} \\ = 0.992[/tex]
We have the final answer as

What is solar system?Solar system is defined as the grouping of the eight planets and their moons in orbit around the sun, as well as other smaller bodies like comets, asteroids, and meteoroids.
It can also be defined as the Sun's orbiting objects are confined by gravity to one system.
An orbiting collection of planets, meteors, or other celestial bodies is referred to as a star system.
The Sun, an ordinary star, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto make up our solar system.
Our solar system is referred to as the "solar system" because our Sun is called Sol after the Latin word for Sun, "solis," and because anything related to the Sun is termed "solar."
Thus, scientists work independently to form theories about the Earth without sharing data.

how many valence electrons does alkali metals gain or lose
Answer:
Alkali metals have 1 valence electron on their outer shell. They are more stable when they have 8 valence electrons, so they want to lose that valence electron. They do this by bonding with other elements. When they lose their 1 valence electron, they have a full octet and are therefore stable.:

Answer:

Explanation:
just took the quiz
We can classify each rock as intrusive or extrusive and basaltic or granitic as follows; Rock A - Extrusive, Basaltic, Rock B - Intrusive, Granitic, Rock C - Extrusive, Basaltic, and Rock D - Extrusive, Basaltic.
Rock A - Extrusive, Basaltic
Rock A is described as having dark-colored large grains, which indicates a fine-grained texture, typical of extrusive rocks. The presence of dark-colored large grains suggests a basaltic composition.
Rock B - Intrusive, Granitic
Rock B is described as having large crystals and a high percentage of silica, which suggests a coarse-grained texture, typical of intrusive rocks. The high silica content and large crystals indicate a granitic composition.
Rock C - Extrusive, Basaltic
Rock C is described as having a fine-grained texture and being light-colored, which are characteristic features of extrusive rocks. The fine-grained texture suggests a rapid cooling, typical of extrusive rocks, and the light color is indicative of a basaltic composition.
Rock D - Extrusive, Basaltic
Rock D is described as being from the Hawaiian volcano area and having no visible crystals. This indicates a glassy texture, typical of rapidly cooled extrusive rocks. The origin from a volcanic area and glassy texture suggest a basaltic composition.

Which statement describes what a thermos does?
A. A thermos makes things warmer
B. A thermos stops heat transfer
C. A thermos makes things cooler
D. A thermos slows heat transfer
A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction
