what is the relationship between nitrogen and carbon-14?
Answer:
The relationship between carbon-14 and nitrogen is that carbon-14 forms from nitrogen atoms and eventual decays into atoms of nitrogen-14.
Explanation:
The relationship between carbon-14 and nitrogen is that carbon-14 forms from nitrogen atoms and eventual decays into atoms of nitrogen-14.
Since carbon-14 contains an unstable nucleus that decays radioactively over time, it is a radioactive isotope of carbon. The atomic nucleus of this substance, which goes by the symbol "C-14," consists of six protons and eight neutrons. On Earth, carbon-12 (C-12), an atom with six protons and six neutrons, makes up the vast bulk of the carbon.
In the high atmosphere of the planet, a nuclear process known as cosmic ray spallation produces carbon-14. High-energy cosmic rays hit with nitrogen-14 (N-14) atoms in the atmosphere, with the majority of these collisions coming from the Sun and other space-based sources.

Answer:
Density of the GasExplanation:
More molecules mean more hits against the container walls. Increasing the number of particles means you have increased the density of the gas. This third factor is part of the ideal gas law, which explains how these three factors -- temperature, volume and density -- interact with each other.
Are two clear liquids mix to create a “chunky” solid a chemical of physical change? Why?
Answer:
Well i know that a chemical change is somthing that can not be undone.
This however is a physical change let me explain.
Even though you mixed two chemicals together to create a new substance does NOT mean it is a chemical change. This however is kinda like a water. You can turn water into a ice cube that does not mean it changed what the water is made out of it just changed the form of the water. Kinda like this. A chemical change would be an example of buring a log once that log has turned into ashs it will never be the log it was before.

You have learned that the atomic number of a chemical is the number of protons found in the nucleus. Atomic numbers can be used to find the number of neutrons and electrons in an atom. In this project, you will practice atomic mass and atomic mass number calculation as well as fill out a chart using the periodic table. Don’t forget to read through the rubric below, so you will know what you will be graded on. When you are ready, upload it replacing the “Lastname” in the saved document name with your last name.
Part I:
The atomic number of the sodium atom is 11. The atomic mass number can be estimated by rounding the atomic mass to 23. From this information, you can find the number of neutrons: 11 protons plus how many neutrons equals a mass number of 23? The number of neutrons would have to be the difference between 23 and 11, which is 12. This fact can be restated this way: 11 protons plus 12 neutrons equals a mass number of 23. For every proton in the nucleus, an electron revolves around the nucleus. Since 11 protons are in sodium, 11 electrons must be in sodium.
Using this information and the Periodic Table from lesson titled Periodic Table fill in the chart below.

Read this passage about Christopher Reeve.
Christopher Reeve was born on September 25, 1952, in New York City. His mother was a journalist, and his father was a professor. As a kid he played sports, did well in school, and liked acting. His passion for acting goes back to playing with his brother when they were little. Reeve acted in his first play at the age of nine. After attending college, taking acting classes, and acting in many plays and movies, Reeve landed his biggest role. In 1978, he played the title role in Superman. He received very positive reviews for his performance and starred as Superman in all the sequels. Reeve was soon acting as the lead role in dozens of movies after Superman. Once well-known, Reeve used his celebrity status for good causes, such as visiting very sick children through the Make-A-Wish foundation. He was also a track and field coach at the Special Olympics.
Besides acting, Reeve was also a licensed pilot and liked horseback riding. He learned to ride horses for a movie role, and he continued riding in his free time. Unfortunately, while riding one day in 1995, Reeve fell from his horse and became paralyzed from the neck down. Being confined to a wheelchair did not hold back Reeve from being socially active, and after many surgeries and rehabilitation, he decided to dedicate his life to helping people with spinal-cord injuries. He created the Christopher Reeve Foundation, which supports the improvement of the lives of people with disabilities and helps fund research to find a cure for paralysis. He was also politically active, working with senators to make sure that people with disabilities were treated fairly in the workplace. Reeve received many awards for his dedication to public service. He also wrote two books about his experiences, and a documentary was made about his life. Reeve passed away in 2004, but his legacy lives on today. He touched the lives of many people and showed us what it means to overcome extreme odds by never giving up.
Based on this passage, Reeve best fits in the yearbook category

what is the density of a small block of wood with a mass of 35g and a volume of 70 cm3
Help plz
Answer:
The density of the wood is 0.5 g/cm³
Explanation:
To calculate density you need to use the formula D = M/V
D = Density
M = Mass (in grams)
V = Volume (in cm³ for solids and mL for liquids)
So, just plug in your given values: D = 35 g ÷ 70 cm³ = 0.5 g/cm³
Voila, you just calculated the density of that piece of wood!
How does Earth's rotation affect ocean currents?
Lesson 2.09
Question 9 options:
It causes them to flow in a curved path
It has no affect
It causes them to flow from east to west
It causes them to flow from north to south
Answer:
Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.
Explanation:
Earth's rotation affect ocean currents because: A. It causes them to flow in a curved path.
What is Earth rotation?Earth rotation can be defined as the amount of time that is taken by planet Earth to complete its spinning movement about an orbital axis.
This ultimately implies that, Earth rotation refers to the time taken by earth to rotate once on its axis. Also, a spinning movement of the Earth on its axis takes approximately 24 hours to complete with respect to the Sun and it result in an effect called Coriolis.
In conclusion, Earth's rotation affect ocean currents because it causes them to flow in a curved path due to Coriolis effect.

Explain the trend in boiling points as you move down group v11
Answer:
Fluorine
Chlorine
Bromine
Iodine
Boiling point increases as you go down the group v11
Explanation:
The elements of Group VII are the halogens consisting of f fluorine (F), chlorine (Cl), bromine (Br), iodine (I). All of which are non metals and exists as diatomic molecules - F2, Cl2, Br2, I2 with intermolecular attractions between the two molecules of each element held by Van der Waals dispersion force.
Moving down the group, the size of the atoms increases in size from Fluorine, F2 and Chlorine, Cl2 which are gases to Bromine , Br2 which exists as a liquid to solid, Iodine, I2. This attributes to the increasing in Strength of the Van der Waals forces as you go down the group. In order to break the vanderwaals forces , More heat energy is required to change thier states leading to the increase in boiling point going down the group.
Fluorine
Chlorine
Bromine
Iodine
Boiling point increases as you go down the group
6. Un átomo de sodio tiene 11 protones, 12 neutrones y 11 electrones, a) ¿cuál es la masa en gramos de este átomo de sodio? b) Si este átomo de sodio pierde un electrón para quedar cargado positivamente (Na+1) ¿Cuál es su nueva masa? ¿cuánto cambió en porcentaje con respecto a la masa original (la del literal a))? c) Si todos los átomos de sodio fueran iguales ¿cuántos átomos de sodio hay en un miligramo?
Answer:
a. 3.851301x10⁻²³g
b. La masa del Na⁺ es 3.85121x10⁻²³g y 0.002% es el cambio percentual.
c. 2.6x10¹⁹ átomos hay presentes.
Explanation:
a. La masa de un electrón es 9.1x10⁻²⁸g
La de un protón es 1.673x10⁻²⁴g
La de un neutrón es 1.675x10⁻²⁴g
La masa del átomo de sodio es:
11*1.673x10⁻²⁴g + 12*1.675x10⁻²⁴g + 11*9.1x10⁻²⁸g =
3.851301x10⁻²³gb) Ahora, con 10 electrones la masa es:
11*1.673x10⁻²⁴g + 12*1.675x10⁻²⁴g + 10*9.1x10⁻²⁸g =
3.85121x10⁻²³gEl cambio percentual es:
3.851301x10⁻²³g - 3.85121x10⁻²³ / 3.851301x10⁻²³ * 100 =
0.002% es el cambio percentual.c. 1 átomo de sodio pesa 3.851301x10⁻²³g, 1mg = 1x10⁻³g tendrán:
1x10⁻³g * (1 átomo / 3.851301x10⁻²³g) =
2.6x10¹⁹ átomos hay presentes
