This question is incomplete, the complete part is as follows:
This equation is unbalanced. Which of the following is the correct balanced equation for this reaction?
A. 4Fe + 3O2 → 2Fe2O3
B. 3Fe + 4O2 → 2Fe2O3
C. 2Fe + 4O2 → 3Fe2O3
D. 3Fe + 3O2 → 4Fe2O3
E. 4Fe + 4O2 → 3Fe2O3
The answer is A. 4Fe + 3O2 → 2Fe2O3
Explanation:
This question involved a chemical reaction between iron element (Fe) and atmospheric oxygen (O2) to produce iron oxide. The equation is given as follows:
Fe + O2 → Fe2O3
However, this chemical equation is NOT balanced and not in accordance with the law of conservation of matter. To balance this equation, we have to make sure that the number of atoms of each element on the reactant side is equal to that on the product side. Hence, we use COEFFICIENTS. The balanced equation is given below;
4Fe + 3O2 → 2Fe2O3

Answer:
More than 8.7 million species are living on the planet. Every single species is composed of a cell and it includes both single-celled and multicellular organisms.
The cells provide shape, structure and carries out different types of functions to keep the entire system active. The cell contains different functional structures which are collectively called Organelles, and they are involved in various cellular functions.

1: What gases are used and expelled by photosynthesis and respiration?
2: Where are the largest concentration of ozone and what value does it have?
3: What happens to the surface of the earth when there is an increase in greenhouse gases?
Answer:
1 Photosynthesis uses CO2 and expels O2 and the reverse for respiration
2. stratosphere where ~90% of it is
3. Less infrared radiation is able to escape from the earth into space and that infrared radiation hits the GHG gases and the radiation is turned into kinetic or heat energy trapping which warms up the earth
Explanation:
Answer:
1. Used by Photosynthesis: CO2 Expelled: O2
Used by Cellular respiration: O2 Expelled CO2
2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”
3. The surface of the earth heats up

What process ensures that all the tissues and organs of an organism are in their characteristic places?
Answer:is any individual entity that embodies the properties of life. ... Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea.
Explanation:
Answer:
Pattern Formation
Explanation:
Cytoplasmic determinants and inductive signals both contribute to the development of a special organization in which the tissues and organs of an organism are all in their characteristic places, a process known as pattern formation.

What is the name of the gradient between high pressure and low pressure?
Answer:
Pressure gradient
Explanation:
Hope this helps :)
Answer:
Pressure gradient
Explanation:
The change in pressure measured across a given distance is called a "pressure gradient". The pressure gradient results in a net force that is directed from high to low pressure and this force is called the "pressure gradient force". The pressure gradient force is responsible for triggering the initial movement of air

Part B: Suppose Steven combined the table-
tennis balls into one large bag instead of two
individual bags. Would the probability change
from Part A if Steven wanted to draw a "1" and a
"B" without replacement?
A. Yes, the probability would change because you
are drawing two table-tennis balls.
B. No, the probability would not change because
the outcome is the same.
o C. Yes, the probability would change because you
are drawing from one bag and this changes the
number of possible outcomes.
D. No, the probability would not change because
there is still one table-tennis ball marked with a
"1" and one table-tennis ball marked with a
"B".

Explanation:
The theory of plate tectonics states that Earth's plates are always in motion. What geological evidence supports this statement?
Continental and oceanic plates differ in densities.
Selsmic activity occurs along plate boundaries.
Less dense plates always subduct beneath the more dense plates.
The sizes and shapes of continents remain the same over time.
Answer:
Seismic activity occur along plate boundaries.
Explanation:
Since the plates are constantly moving, the places where the plates meet, the boundaries, have seismic activity.
The geological evidence that supports this statement is that seismic activity occurs along plate boundaries. So, the correct option is B.
What are tectonic plates?Tectonic plates are huge slabs of rock that divide Earth's crust and move constantly to reshape the Earth's landscape. Such plates are also known as lithospheric plates and are generally composed of both continental and oceanic lithosphere.
Since the tectonic plates are constantly moving and the places where the plates meet and form the boundaries have seismic activity.
Therefore, the geological evidence that supports this statement is that seismic activity occurs along plate boundaries.

A. What are the two main types of seismic waves that are created during an
earthquake? p waves s waves surface waves
Explanation:
There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.
