Write a 125 word summary of what you have learned in "Introducing the Microscope". Be sure to include steps on how to focus, how to solve for magnification, and what a field of view is and how to measure it.
Answer:
Introduction to Basic Microscopy. Microscopes are specialized optical instruments designed to produce magnified visual or photographic (including digital) images of objects or specimens that are too small to be seen with the naked eye.
Microscope are the important tools which are used by scientist. For example, in material science, medicine, mineralogy and microbiology.
Light microscope is able to send light. Light is being focused in a tight breath whereby that light passes through a sample which later it is able to create an image. This image passes to different lenses which magnifies it until it reaches the camera.
There are different types of microscope for example, Compound light microscope, Simple light microscope, and monocular microscope.
In simple light microscope only one lens which which is being used to magnify an object and it is not able to reach to a higher magnification.
In compound light microscope it uses two lenses to produce image. For example eyepiece lens and objective lens.

item 3 steel is an alloy containing fe atoms and c atoms. which of the following diagrams best represents the particle-level structure of steel?
An alloy is obtained when an element is combined with another physically and not chemically. The image that accurately represents steel is the image in which carbon atoms are sandwiched between iron atoms.
Steel is an alloy of iron and carbon. In an alloy, the atoms one element is sandwiched in between atoms of another element in its crystal. Usually, allows are formed to improve certain desired properties of substances. The percentage of carbon included in steel depends on its intended use.
The image that can be used to represent the formation of steel is the image shown in B. In that image, small atoms of carbon are seen sandwiched between larger iron atoms. That is the accurate description of steel.

If 5 J (joules) of electrical energy is used to power an iron, how many joules of heat and steam should it be transformed into?
Answer:
maybe 25 joules
Explanation:
please mark me as a brainlist
If 5 J (joules) of electrical energy is used to power an iron, 25 joules of heat and steam should it be transformed into.
What is energy?Energy is referred to by scientists as the capacity for work. People have figured out how to transform energy from one form to another and then use it to accomplish tasks, making modern civilization possible.
Walking and bicycling, driving cars on roads and boats through water, cooking meals on stoves, making ice in freezers, lighting our homes and workplaces, producing goods, and sending astronauts into space all require the usage of energy.
Energy is capable of changing its forms. For instance, a person's body stores chemical energy from the food they consume until they may use it as kinetic energy when working or playing.
Therefore, If 5 J (joules) of electrical energy is used to power an iron, 25 joules of heat and steam should it be transformed into.

If 84.5 mol of an ideal gas occupies 21.5 L at 305 K, what is the pressure of the gas? pressure: atm
Answer:
98.367 atm
Explanation:
For this, you must use the equation PV=nRT. Since you are looking for P, rearrange the equation so that P= nRT/V.
Now collect the information you have:
n (mol) = 84.5
R (ideal gas constant to find atm not every case) = .08206
T (temperature) = 305 K (always convert to kelvin)
V (volume in liters) = 21.5
Now Use P= (85.5 mol)×(.08206)×(305 K)/(21.5) to get your answer in atm
