Answer:
Phosphorus pentoxide is a chemical compound with molecular formula P4O10 (with its common name derived from its empirical formula, P2O5). This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant and dehydrating agent.
The molecule P2O5 is named "diphosphorus pentoxide," representing a compound composed of two phosphorus atoms and five oxygen atoms bonded together.
Diphosphorus pentoxide is a chemical compound with the molecular formula P2O5, consisting of two phosphorus atoms and five oxygen atoms bonded together.
It exists as a white, odorless solid or a colorless, viscous liquid depending on temperature and pressure. Diphosphorus pentoxide is a powerful desiccant and a crucial component in the manufacturing of various phosphoric acids, fertilizers, and chemical compounds.
It is also used in laboratory settings for dehydration reactions and as a reagent in organic synthesis. Due to its corrosive nature, handling diphosphorus pentoxide requires proper safety precautions and careful storage.

what inferences can we make regarding earthquake magnitude, frequency, or concentration
Answer:
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

Explanation:
In a free-market economy, the forces of demand and supply work together to set the prices for goods.
The government has no control over price action.
In a market economy, demand and supply determine the rate of production. Demand is controlled by the want and needs of consumers. Supply responds to this by either increasing or decreasing production. In turn, the price of commodities takes shape due to these forces.Answer:

What is the HELIOCENTRIC model of the solar system?
Answer:
The heliocentric model of the solar system is the one that suggests that the sun is in the center of the universe and everything revolves around it.
Explanation:
There have been few models throughout history when it comes to the arrangement and hierarchy of the objects in space. Most of them have been wrong, though they have persisted for a very long time. Some, like the heliocentric model, got some basics right, but it still had some mistakes which from today's perspective are big ones.
The heliocentric model suggests that the Sun is the center of the universe, with all other objects in space orbiting around it. Now, it did guess right that the planets in the solar system revolve around it and that it is in the center of it, but it made a big mistake by putting the Sun in the center of the universe, not just the solar system. Not just that the Sun is not in the center of the universe, it is not even close to the center of the galaxy in which it is, nor it is the largest object or the one with the biggest gravity so that it attracts everything around to revolve around it.

Find the midpoint between (0,0) and (-4,-12)
(29) and (5,1)
Answer:
-2, -6
[tex]\frac{7}{2}[/tex] , 5
Explanation:
Given coordinates;
(0,0) and (-4,-12)
(2, 9) and (5,1)
Unknown:
Midpoints of the coordinates = ?
Solution:
The coordinates of the midpoint are given as;
x[tex]_{m}[/tex] , y[tex]_{m}[/tex] =( [tex]\frac{x_{1} + x_{2} }{2}[/tex] , [tex]\frac{y_{1} + y_{2} }{2}[/tex])
Now;
x₁= 0 x₂ = -4 y₁ = 0 y₂ = -12
Input the parameters and solve;
x[tex]_{m}[/tex], y[tex]_{m}[/tex] = [tex]\frac{0+(-4)}{2}[/tex] , [tex]\frac{0+ (-12)}{2}[/tex] = -2, -6
For (2, 9) and (5,1)
x₁= 2 x₂ = 5 y₁ = 9 y₂ = 1
x[tex]_{m}[/tex], y[tex]_{m}[/tex] = [tex]\frac{2 + 5}{2}[/tex] , [tex]\frac{9 + 1}{2}[/tex] = [tex]\frac{7}{2}[/tex] , 5

Humans have changed the environment by evolving and using natural resources, with the natural resources slowly dwindling down is will affect the earth greatly. The earth won't be able to regenerate the resources fast enough for us to use them. The consequences are that we will burn up the earths valuables and end up stripping the earth of primary resources, making the earth weaken and have nothing to provide animals or other living creatures.

showing how trends change over time.
comparing information from different sources.
A line graph like this one is most helpful for showing how trends change over time. The correct option is c.
Line graphs are used to chart changes over short and long time periods. Line graphs are preferable to bar graphs when there are little changes. Line graphs can also be used to compare changes in more than one group during the same time period.
A line graph is a type of graph that is widely used to show change over time as a set of data points linked by segments of straight lines on two axes. As a result, the line graph aids in determining the relationship among two sets of values, with one set of information always being dependant on the other.
