Have a good day and drink some water plz

The food molecules during cellular respiration they undergo chemical reactions with oxygen, releasing stored energy.

Chemical reaction is defined as a procedure in which one or more substances, known as reactants, are converted into one or more different substances, known as products.

It can also be defined as a method of chemically transforming one set of chemical substances into another.

There are basically six types of chemical reaction.

Cellular respiration is defined as the process of oxidizing biological fuels in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, which drives the bulk production of ATP.

It can also be defined as the process by which sugar from food is converted into energy within cells.

Thus, the  food molecules during cellular respiration they undergo chemical reactions with oxygen, releasing stored energy.

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.

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.

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:

The number of valence electrons increases from left to right.

Explanation: The number of valence electrons increases going across a period, or row in the periodic table, for example, group 1 elements have 1 valence electrons and group 2 elements have have 2.

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.
