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.

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.

Explanation:

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.

C) equally shared and form nondirectional bonds

In metals, electrons are free to move as described by the electron sea model. Electrons are shared equally among atoms, and the structure is based on simple close-packed structures that contain no fixed directional bonds.

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

Answer:

Carbon dioxide serves as the source of carbon,

Explanation:

Answer:

Water

Explanation:

Water is oxidized in photosynthesis, which means it loses electrons, and carbon dioxide is reduced, meaning it gains electrons

Answer:

No.

Explanation:

The reason for this is if everything in an ecosystem was a producer there would be nothing consuming and soon the ecosystem would be overwhelmed by two many products and nothing to consume them. A healthy ecosystem is a balanced cycle that makes sure everything is working properly and everything benefits something else. A food chain of sort is often seen in a balances ecosystem to show how everything is useful and needed. So in answer if there were only producers an ecosystem wouldn't thrive at its full potential, if at all.

Answer:

Ionic compounds are electrically neutral because the charges of the cations and anions that make up the compound cancel each other out. In the case of salt for example, sodium has a charge of positive one, and chloride has a charge of negative one. Together, they neutralize the compound.

Explanation:

Covalent bonding can be defined as the sharing of electrons between two atoms.

The statement which best explains the difference between polar and nonpolar covalent bonds is "Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally"

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.
