1. Which of the following is neutrally charged?
c. an electron
b. a compound d. a proton
a. an ion
d. a proton
Answer:
B. A compound
Explanation:
An ion is defined as a charged particle, so it's not going to be that. Ions can be positively or negatively charged.
Electrons are tiny particles, smaller than an atom, that revolve around the nucleus. They have a negative charge. So they are not neutral either
Protons are also a part of atoms, like electrons are. An atom is neutral overall. This is because protons have a positive charge that balances out the negative charge of electrons.
So, the only answer option we have left is for a compound. So, that's our answer!
Answer:
c. an electron
Explanation:
A neutral charge is the electrochemical occurrence where an atom has an equal number of electrons and protons. Such an atom is neither positively charged nor negatively charged because the protons and electrons balance each other out

What is the quantum mechanical electron configuration of arsenic?
Answer:
After the 4s sublevel is filled with two electrons, ten electrons fill the 3d sublevel, which is slightly higher in energy than the 4s sublevel. After the 3d sublevel is filled, the remaining three electrons will be in orbitals in the 4p sublevel. Thus, the electron configuration for arsenic is [Ar] 4s(2 squared) 3d(10 squared) 4p(3 squared).
1. What process occurs along divergent plate boundary?
2. What geologic features formed when two plates moved away from each other?
3. Compare rift valley from mid-ocean ridge. Explain your answer. PIVOT 4A CALABARZON 24
1. Earthquakes and Eruptions (volcanoes)
2. Divergent plate boundary
3. Apart from a widening valley, it equally contributes to steep mountain sides spreading. A mid-oceanic ridge is naturally produced if two oceanic plates naturally start moving away from each other.
Explanation:1. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below. It responds by melting, and the new magma flows into the fissure. The magma then solidifies and the process repeats itself.
2. When two plate diverge from each other also known as divergent (di-apart, vergere- to inclined) plate margin .
Two plate diverge along oceanic ridges where new lithosphere is created.
Now come to the main point: Geological Features
When two oceanic plate diverge then new sea floor is created by a process called sea floor spreading and features like Mid oceanic ridges, volcanoes & Young lava flows forms. Ex. East Pacific Rise, Mid-Adlantic Ridge.
When two continental plates diverge by continental rifting then features like Rift valley, volcanoes are found. Ex of continent continent -East Africa rift vally, Red sea.
3. The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley. ... If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge.

An image of Earth's layer is above.
Which layer is the most dense?
layer A
layer B
layer C
layer D
Answer:
Layer D
Explanation:
Earth's interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere.

Answer:
Congestive heart failure
Explanation:
Congestive heart failure happens when your heart gets too weak to pump blood from the lungs out to the body. Pressure builds up in the heart which puts pressure on the blood vessels of the lungs. This will lead to leakage of the vessels and the fluids build up in the air sacs of the lungs. This condition is called pulmonary edema.
Pulmonary edema occurs when fluid builds up in the lungs making it hard to breathe. It may start out as running out of breath easily but if left untreated (both conditions) symptoms get worse over time.

A lunar eclipse occurs at night and can only occur during what phase of the moon?
New moon
Full moon
Answer:Full moon
Hope this helps :)
A lunar eclipse can occur only at full moon.
Explanation:
During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth's shadow covers the Moon.
Answer:
"Full moon"
A full moon would be needed due to the fact that the sun would need to entirely block it, resulting in a solar eclipse. Hence, the answer is "Full moon".
A student makes a diagram that shows the layers of Earth. The student incorrectly claims that the density of each layer is the same. Which of these accurately describes the
layers of Earth?
The density of Earth's layers increases from the center to the surface,
The density of Earth's layers increases as you move down toward the center.
The mantle is less dense than the layer above it but denser than the layer below it.
The outer core is denser than the layer below it but less dense than the layer above it.

Which tool should Darla and Rob use to measure the force that pulls a car down the map
Answer:
C. A Spring Scale
Explanation:
Using process of elimination, we can quickly decide that a stopwatch and a ruler will not be useful in measuring the force. This leaves us with either the spring scale or a balance scale. A balance scale is used to compare two weights, so this is eliminated. That leaves us with a spring scale. This is because we can attached the spring scale to the car and when we let it go, we can record the force. I hope this helps!
