Which is the properly balanced equation for the process in which iron oxide (Fe2O3) and carbon monoxide (CO) react to produce iron (Fe) and carbon dioxide (CO2) gas?A.
Fe2O3 + CO → Fe + CO2

B.
Fe2O3 + 3CO → 2Fe + 3CO2

C.
2Fe2O3 + 3CO → 2Fe + 3CO2

D.
3Fe2O3 + CO → 3Fe + 2CO2

Answers

Answer 1

Answer: B. Fe2O3 +3CO --> 2Fe + 3CO2

Fe has 2, Fe2 ---> 2Fe
O has 6, O3 + 3O (3+3=6) ---> 3(O2)(3x2=6)
C has 3, (3C --> 3C)

none of the other equations make sense:
In A, Fe on the left has 2 while Fe on the right has 1(so you can eliminate that.)
in C, Fe on the left has 4 (2x2) while Fe on the right has 2.(eliminate this too.)
in D, Fe on the left has 6 (3x2) and Fe on the right has 3 (eliminate this)

In what ways are organisms in the Bacteria and Archae Kingdoms alike?

Answers

Archaea have generally the same shape, size, and appearance as bacteria. Like bacteria, Archaea multiply by binary fission and move primarily by means of flagella. These morphological similarities can make it difficult to visually tell a bacterium and an archaean apart. Additionally, archaea are more phylogenetically similar to eukarya than bacteria is to either of them.

D.
electromagnetic waves

Answers

Electromagnetic waves best describes the signals sent and received by satellites. Therefore, the correct option is option D.

What is electromagnetic waves?

In classical physics, electromagnetic radiation refers to the movement of energy through a material medium or across empty space at the speed of light in the form of the magnetic and electrical fields that comprise up electromagnetic waves like electromagnetic radiation, visible light, including gamma rays.

Time-varying magnetic and electric fields are linked to one another at right angles or perpendicular towards the direction that of motion in such a wave. The strength and wavelength v of the time fluctuation of the magnetic and electricity fields define an electromagnetic wave. Electromagnetic waves best describes the signals sent and received by satellites.

Therefore, the correct option is option D.

particles that have enough energy to break free from each other and move around freely and spread out from each other is a gas or liquid?

Answers

Gas particles are able to break free and move around freely.

The way that a fluid flows depends on several factors. Briefly describe the factors – use as much scientific vocabulary that you can.

Answers

Answer:

Factors that influence flow :

Flow patterns in a fluid (gas or liquid) depend on three factors: the characteristics of the fluid, the speed of flow, and the shape of the solid surface. Three characteristics of the fluid are of special importance: viscosity, density, and compressibility. Viscosity is the amount of internal friction or resistance to flow. Water, for instance, is less viscous than honey, which explains why water flows more easily than does honey.

All gases are compressible, whereas liquids are practically incompressible; that is, they cannot be squeezed into smaller volumes. Flow patterns in compressible fluids are more complicated and difficult to study than those in incompressible ones. Fortunately for automobile designers, at speeds less than about 220 miles (350 kilometers) per hour, air can be treated as incompressible for all practical purposes. Also, for incompressible fluids, the effects of temperature changes can be neglected.

Students are completing a table about a particular subatomic particle that helps make up an atom.A 3-column table with 2 rows. The first row has entries Mass (a m u), location, charge. The second row has entries 1/2,000, nothing, has a charge.

What best explains how they should complete the table?

with “Inside the nucleus,” because the particle is a proton
with “Inside the nucleus,” because the particle is a neutron
with “Outside of the nucleus,” because the particle is a proton
with “Outside of the nucleus,” because the particle is an electron

Answers

Answer:

with “Outside of the nucleus,” because the particle is an electron

Explanation:

The table is best completed with “Outside of the nucleus,” because the particle is an electron.

The particle being described is an electron.

Electrons are negatively charged particles with a mass that is about $(1)/(2000)$ of protons and neutrons

Mass(a.m.u) location charge

$(1)/(2000)$ outside of the nucleus negative charge

Electrons orbits round the nucleus in distinct energy levels.

Final answer:

The subatomic particle described in the table is an electron, which is found outside of the nucleus of an atom.

Explanation:

The particle described in the table has a mass of 1/2,000 atomic mass units (a.m.u) and carries a charge. Based on this information, we can conclude that the particle being described is an electron. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom, meaning they are found outside of the nucleus. Therefore, the correct entry for the location column in the table should be Outside of the nucleus.
