How do planetary geologists study rocky planets?
Answer:
Planetary geologists study rocky planets by comparing them to Earth.
Explanation:
A planetary geologist is someone who studies how other planets form and evolve over time. Planetary geologists work in the field, laboratory, and -indirectly- in outer space through imagery and other data returned by spacecraft.

Susan made observations about outside events she noticed throughout the day. The day began with rain. Susan saw puddles on the road. The rain stopped and the sun began to shine. The puddles disappeared. Later, clouds began to form in the sky. How do the parts of the water cycle relate to the events that Susan saw?
Answer:
Rainfall - precipitation
disappeared puddles - evaporation
cloud formation - condensation
Explanation:
Rainfall that is observed by the Susan is the precipitation of the water cycle in which the water vapor that was condensed become heavy and form droplets of water and fall from sky to the earth surface.
Puddles that formed due to rainfall are the collection of water in the water cycle which is evaporated (process: evaporation) into the atmosphere n the form of water vapor which condensed to form clouds.
Calculate the number of moles of neon gas in 8.15 atoms of neon gas
Answer:
13.5 moles Ne
Explanation:
Atoms --> Moles
1. Put the given number over 1
2. Multiply by 6.022x10^23 to get to moles
3. Round by sigfigs
(8.15x10^24 atom Ne(g)/1) (1 atom Ne(g)/6.022x10^23molesNe)=13.5337...

What does an elements location tell us about the forces within an atom?
Answer:
Forces inside the atom
The atom is comprised of three major particles—protons, neutrons and electrons. There are four forces (Electromagnetic, Strong, Weak, and Gravity) that are responsible for the behavior of the particles and thus keep the atom together.
how to draw Bohr Model of Phosphorus??
Answer:
look at the image below
Explanation:
The Bohr model of phosphorus depicts 15 electrons in different energy levels, with the nucleus at the center.
Two electrons are present in the first energy level, eight electrons are present in the second and five electrons are present in the third. The electron configuration of phosphorus, which is [tex]1s^2 2s^2 2p^6 3s^2 3p^3[/tex], matches this distribution.
The formula [tex]2n^2[/tex], where n is the energy level number, determines the maximum number of electrons in each energy level. Therefore, the first energy level can accommodate only two electrons, the second energy level up to eight, and the third energy level up to eighteen.

The density of this material is 2 g/cm^3.There are 24 cm^3.
What is the total mass?
Answer:
[tex]\boxed {\tt 48 \ grams}[/tex]
Explanation:
Mass can be found by multiplying the density by the volume.
[tex]m=d*v[/tex]
The density is 2 grams per cubic centimeter.
The volume is 24 cubic centimeter.
[tex]d= 2 \ g/cm^3 \\v=24 \ cm^3[/tex]
Substitute the values into the formula.
[tex]m= 2 \ g/cm^3 *24 \ cm^3[/tex]
Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.
[tex]m= 2 \ g * 24[/tex]
[tex]m= 48 \ g[/tex]
The mass of the material is 48 grams.

Explanation:
what information does the spectrum give about the source of the element?
Answer:
A continuous spectrum can identify elements by the presence of dark bands, and it also tells scientists how hot the object is: As the temperature goes up, the spectrum has increasing amounts of green, blue and violet colors. Relatively cool objects have a spectrum that has mostly deep red or red and yellow.

If 6.5 g of magnesium ribbon reacts completely
with hydrochloric acid, how many grams of
hydrogen gas would be liberated? Mg , + 2HC1(ag)
→ MgC1 + H, [H = 1.0, Mg = 24.0]
Answer:
The mass of hydrogen gas liberated is 0.6 g.
Explanation:
Given data:
Mass of Mg = 6.5 g
Mass of hydrogen gas liberated = ?
Solution:
Chemical equation:
Mg + 2HCl → MgCl₂ + H₂
Now we will calculate the number of moles of Mg.
Number of moles = mass / molar mass
Number of moles = 6.5 g/ 24 g/mol
Number of moles = 0.3 mol
Now we will compare the moles of Mg with hydrogen gas.
Mg : H₂
1 : 1
0.3 : 0.3
Mass of H₂:
Mass = number of moles × molar mass
Mass = 0.3 mol × 2 g/mol
Mass = 0.6 g
What is the mass of 6.02 × 10²³ hydrogen atoms
Answer:
1.0 something depending on your periodic table.
Explanation:
You are given atoms. Not molecules. The mass is what you would read from the periodic table. 1.000 in some form is the answer.
In nature, Hydrogen is found as H2 everywhere except in the sun or a star. The molecular mass (not the atomic mass) would be 2.000 something.

A _____ state is when the electron is closest to the nucleus.
Answer:
ground state
Explanation:
A ground state is when the electron is closest to the nucleus.
What is the ground state of an atom?The ground state of an electron is the state of the lowest energy for that electron. The nucleus is surrounded by electrons that occupy orbitals of varying energy levels.
When an electron jumps to an energy state greater than its ground state, then it is in an excited state. An electron can become excited from the ground state to the excited state if it is given extra energy in the form of a photon, or packet of light.
An electron occupies the lowest energy level that is closer to the nucleus when the electron is present in the ground state.
