Answer: FeO is called ferrous oxide while Fe2O3 is ferric oxide
Explanation:
Ferrous oxide, commonly known as iron(II) oxide contains iron that lost 2 elections in the oxidation process. So it is able to bond with other atoms that have an extra 2 electrons to share. Ferric oxide, is commonly known as iron(III) oxide

Answer:
Plants need energy from the sun, water from the soil, and carbon from the air to grow. Air is mostly made of nitrogen, oxygen, and carbon dioxide. So how do plants get the carbon they need to grow? They absorb carbon dioxide from the air.

Who used scientific investigations to study atoms? Check all that apply.
Answer:
In the early 1900s, Ernest Rutherford studied (among other things) the organization of the atom — the fundamental particle of the natural world. Though atoms cannot be seen with the naked eye, they can be studied with the tools of science since they are part of the natural world.

In the rock cycle, which rock type may be weathered to become sediment, and eventually sedimentary rock?
I. Igneous Rock
II. Sedimentary Rock
III. Metamorphic Rock
I and II only
I and III only
II and III only
I, II, and III
i think it is I. and III.

Answer:
d (I think)
Explanation:
the rock cycle is a very slow, but natural process, and it may skip a stage (for example, metamorphic rocks might skip the igneous stage and weather right to sedimentary) if this is incorrect, I apologize

No matter where the moon is in its orbit around Earth, how much is it lit up?
Where the light source come from?
PLZ HELP IRS DUE TODAY
Answer:
the light comes from the sun
Explanation:
the light from the sun reflects on the moon and the moon gets its light.
The moon is always half-lit by the light that comes from the sun except during the lunar eclipse. The light source for the moon is the sun.
What are the phases of the moon?The lunar phase or Moon phase can be described as the shape of the Moon's directly sunlit portion, which can be demonstrated quantitatively using areas or angles, or qualitatively utilizing the terminology of the four major phases: new moon, first quarter, full moon, last quarter.
The lunar phases gradually change over a month as the Moon's orbital positions around Earth and the position of the Earth around the Sun shift. The visible side of the Moon is sunlit, according to the position of the Moon in its orbit.
Thus, this face's sunlit part of the moon can vary from 0% to 100%. Each of the 4 major lunar phases is approximately 7.4 days, with +/− 19 hours in variation due to the elliptical shape of the orbit of the Moon.

Which of the following are found as the lithosphere moves a volcano away from a mantle plume?
a- sea mounts
b- lithospheric mountains
c- subduction zones
d- none of these
Answer:
c- subduction zones
Explanation:
A mental plum is generally found within the mantel and is a mechanism of convection, the plume is often invoked as the causes of volcanic hotspots. Such can be seen on Iceland and Hawaii islands. They represent a large volume of volcanism near the plate boundary. Mantle plumes are believed to be a source of molten magma from the earth.Based on the following electronegativity values, which of the following best explains the polarity of the bond formed?

As the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.
What is effective nuclear charge?Effective nuclear charge of an atom is the attraction force of positive charge of protons present inside the nucleus acts as an valence electrons.
The effective nuclear charge is alway slower than the total number of protons of the nucleus because of shielding effect. Where Z is the atomic number and S is the number of shielding electrons.
Therefore, the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.

A scientist observes hot water erupting from a vent in the Earth.What most likely caused the water to rise and erupt from the vent? someone pls answer i if u answer u get 57 points
Answer/Explanation:
A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.
