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.

How does increasing the temperature affect a reaction?
A. An increase in temperature slows down the reaction.
B. An increase in temperature increases the reaction rate.
C. An increase in temperature lowers the reaction's activation energy.
D. An increase in temperature changes equilibrium concentrations.
SUBMIT
Answer:
b
Explanation:
The concept Arrhenius equation is used here to determine the temperature dependence of the rate of a reaction. An increase in temperature increases the rate of a reaction. The correct option is B.
What is Arrhenius equation?The rate of a chemical reaction is affected by the factors like temperature and activation energy. The influence of these factors on the rate of the reaction is explained by the Arrhenius equation.
The equation is given as:
[tex]k = A. e^{-} ^{E_{a} } /RT[/tex]
k - Rate constant
A - Frequency factor
Eₐ - Activation energy
R - Gas constant
T - Temperature
Since 'Temperature' appears in the denominator of the negative power of the exponential factor of the equation, it is evident that an increase in temperature increases the value of rate constant and thereby increases the rate of the reaction.
Thus the correct option is B.

Which element's atoms are most likely to touch each other without overlapping?
iron
hydrogen
carbon
radon
Answer: iron
Explanation: Metals' atoms are closely bonded in a crystal lattice. In metallic bonds, the electron cloud boundaries of atoms touch each other. Many nonmetals occur as diatomic molecules. The electron clouds of these two bonded nonmetal atoms overlap .
Hydrogen atoms are most likely to touch each other without overlapping because of their small size and simple atomic structure.
A hydrogen molecule is a particle of the synthetic component hydrogen. The electrically unbiased molecule contains a solitary emphatically charged proton and a solitary adversely charged electron bound to the core by the Coulomb force. Nuclear hydrogen is around 75% of the baryonic mass of the universe.
Hydrogen exist as diatomic particle, I.e., it can exist by attaching to another hydrogen. You realize that hydrogen has just a single electron in it's furthest and just shell. Yet, to accomplish a steady design, there should be two electrons in this shell. So two hydrogen molecules share their electrons by holding.

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).

Lines of equilibrium, also known as phase boundaries, or circumstances under which different phases may exist at equilibrium, are typical elements of a phase diagram. Phase changes take place along equilibration lines. Despite their frequent occurrence, metastable phases are not equilibrium phases, hence they are not depicted on phase diagrams.

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.

You have a gas sample of carbon dioxide at 298 K. If the pressure is 0.827 atm what is the pressure in mmhg
Answer:
628.520 mmHg
Explanation:
1 atm = 760 mmHg
[tex](760 \div 1) \times 0.827[/tex]
The pressure of 0.827 atm in mmHg is 628.52 mmHg
Pressure has various units of measurement such as atmosphere (atm), pascal, mmHg, Newton per square metre (N/m²) etc. These units can be converted from one to the other.
Considering the question given above, we can convert 0.827 atm to mmHg as illustrated below:
1 atm = 760 mmHg
Therefore,
0.827 atm = 0.827 × 760
0.827 atm = 628.52 mmHg
Thus, 0.827 atm is equivalent to 628.52 mmHg

The rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.
What are rock cycle?The rock cycle is defined as the process through which the three main rock types i.e. igneous, metamorphic and sedimentary rock transfer from one type to another type.
The plate tectonics is defined as a theory that earth's outer shell is divided into large slabs of solid rocks known as "plates" that glide over earth mantle, the rocky inner layer above earth's core.

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!
