Answer:
2 moles ofFerric Oxide () over 4 moles of Fe
Explanation:
Firts of all I want to explain the nomenclature that is involve in the equation:
Ferric Oxide
Carbon
Iron
Carbon Dioxide
Now, to understand the ratio from the balanced equation its necessary read the equation with the respective coefficients, for example:
- 2 moles of Ferric Oxide (
) reacts to produce 4 moles of Iron (
)
- 3 moles of Carbon (
) reacts to produce 4 moles of Iron (
- 2 moles of Ferric Oxide (
) reacts to produce 3 moles of Carbon Dioxide (
)
Each of the above could be represent as a ratio, but is always necessary keep the respective coefficient, then if you read each option only the first has the respective coefficient, it means:
2 moles of Ferric Oxide () reacts to produce 4 moles of Iron (
) or, in other words, 2 moles ofFerric Oxide (
) over 4 moles of Iron 4 (
)

In general, a good sample is which can represent as much as possible the characteristics of the population. In the language of measurement, meaning that the sample must be valid, which can measure something that should be measured. A valid sample is determined by two considerations.
First: The accuracy or precision, the degree of absence of "bias" (error) in the sample. In other words, the less the error rate is in the sample, the more accurate the sample. Benchmarks for "bias" or error is population.
Cooper and Emory (1995) states that "there is no systematic variance"that means is there is no diversity of measurement due to the influenceof known or unknown, which led to scores tend to lead to a certainpoint.
Second: Precision. The second criterion is to have a good sample estimate of the level of precision. Precision refers to the question of how close we are to estimate population characteristics. There has never been a sample that can fully represent the characteristics of the population. Therefore,in each sampling always attached keasalahan-error, which is known as"sampling error" Precision is measured by standard deviation (standarderror). Thesmaller the difference between the standard deviation obtained from thesample (S) with a standard deviation of the population (s), the higherthe level of precision. Thoughnot always, the level of precision may be increased by adding thenumber of samples, the fault may be reduced if the number of samplesplus (Kerlinger, 1973).

Igneous rocks that cools very quickly when it forms may have a texture that is smooth and shiny with no visible grains.
What are igneous rocks?
Igneous rocks also called as magmatic rocks is one of the three main rock type present the other two being sedimentary and metamorphic rocks.These rocks are formed by cooling and solidification of magma or lava .
The magma is derived from from partial melts of rocks which are existing in the earth's crust or mantle.Melting is caused by one of the three processes increase in temperature, change in composition or decrease in pressure.
Igneous rocks are classified based according o their occurrence, texture, chemical composition or mineral content.According to their mode of occurrence they are classified as intrusive or extrusive igneous rocks.

A sandblasted rock should be much smoother, since the sand blasts away any rough edges. It will, however, be slightly smaller due to losing those edges.
A sandblasted rock differs from a non-sandblasted rock in various aspects, including a change in texture and color of the rock's surface.
Sandblasting is a process in which a high-pressure stream of sand or other abrasive material is used to remove material from the surface of an object.
The most noticeable difference between a sandblasted rock and one that hasn't been sandblasted is the texture of the surface. A sandblasted rock will typically have a rough, pitted surface, while an unsandblasted rock will have a smoother surface.
Sandblasting can also change the color of a rock. If the rock has a layer of surface material that is a different color than the underlying rock, sandblasting can remove the surface layer and expose the underlying rock.
Therefore, a sandblasted rock would differ from a rock that hasn't been sandblasted in several ways such as change in texture and color of a rock's surface, creating a rough, pitted texture and exposing the underlying rock.
