Let’s assume the clothes in the dryer are made of cotton. Cotton is made of long chains of carbon atoms that form fibers. Determine the number of protons, neutrons, and electrons in an atom of carbon using the information on the right.
Answer:
Protons = 6
Electrons = 6
Neutrons = 6
Explanation:
Given that:
Atomic number of C = 6
Mass number of C = 12
No. of protons:
We know that atomic number is the number of protons, so:
Protons = 6
No. of electrons:
Protons = electrons so:
Electrons = 6
No. of neutrons:
= Mass number - Atomic No.
= 12 - 6
Neutrons = 6

Which chemical process generates the atp produced in glycolysis?.
Atp is a form of energy and it is generated through a chemical process called substrate level phosphorylation.
What is substrate level phosphorylation?Substrate-level phosphorylation is a reaction that makes use of substrate to generate Adenosine triphosphate (ATP) which is a form of energy.
ATP is produced through the transfer of phosphate group from the substrate directly to adenosine diphosphate (ADP).
Therefore, substrate-level phosphorylation generates the atp produced in glycolysis.

Over long periods of time, the climate of an area can change. Which of these can cause a change in climate?
Answer:
You didnt give use the choices you have but I can try to help. Climate can change when it snows,rains,when it is sunny,or cloudy.
Explanation:
The rain allows the climate to cool down depending in the weather out. Same with cloudy weather. Snow can also cause temperature to drop down. When it is sunny, the climate in the sun will be warm, until getting in the shade and it gets cold again.

Consider the following reaction: 2Mg + CO2 <--> 2MgO + C . A laboratory technician wants to increase the amount of MgO produced. Which of the following is the best way to accomplish this?
Add catalyst
increase the carbon
decrease the carbon
decrease the Mg
This problem is providing the equilibrium reaction between magnesium and carbon and asks for a way to increase the amount of magnesium oxide, a product. Thus, the answer turns out to be decrease the carbon.
Le Cha telier's principle.In chemistry, when a chemical reaction attempts to go to completion, it might experience a limitation known as equilibrium; a condition where it is not able to proceed any further.
In such a way, for the given reaction:
[tex]2Mg+CO_2\rightleftharpoons2MgO+C[/tex]
One can see that the increase of magnesium oxide, as required, can be accomplished by either increasing any reactant or removing any product in order to shift the equilibrium towards it.
In such a way, one concludes that the correct choice is decrease carbon as it will shift the reaction towards the product; however, we must keep in mind that neither solid nor liquid species contribute to the equilibrium.

Which water sample (A, B or local sample) was more acidic to begin with.
what is your reasoning?
Answer:
B
Explanation:
Sample B takes more drops for both P- and T-alkalinity tests to reach pH 8.3 and 4.5. So it is more acidic to begin with.
pH is equal for all three.
Now look at the drops amount
21<52<25Higher the drops lower the solubility or its less acidic.
So sample A is most acidic then local then sample B

I HOPE IT HELPS YOU PLEASE MARK ME BRAINLIEST IF YOU ARE SATISFIED BY THE ANSWER:)If more greenhouse gasses were added to the atmosphere, what would happen to Earth's heat budget and the planet's temperature?
Answer:
Global Warming!
Explanation:
Greenhouse gases help keeping the Earth warm for example; Carbon dioxide, methane etc. But recently there has been too much pollution which produced more greenhouse gases like; carbon dioxide...Usually trees and plants would help in keeping the air clean by eliminating carbon dioxide but as we know trees are being cut down. Which increases the amount of CO2 (chemical formula of Carbon dioxide) and they capture more heat. Which causes the temperature to gradually increase in earth and ice caps to melt in Antarctica, and causes the water levels to rise.

How
molecules of iron (iii) oxide
many
can be produced from 13.5 moles fe?
The number of molecules of iron (iii) oxide F₂O₃ that can be produced from 13.5 moles of Fe is 4.06×10²⁴ molecules
Balanced equation4Fe + 3O₂ —> 2F₂O₃
From the balanced equation above,
4 moles of Fe reacted to produce 2 moles of F₂O₃.
Therefore,
13.5 moles of Fe will react to produce = (13.5 × 2) / 4 = 6.75 moles of F₂O₃
How to determine the number of molecules of F₂O₃ produced
From Avogadro's hypothesis,
1 mole of F₂O₃ = 6.02×10²³ molecules
Therefore,
6.75 moles of F₂O₃ = 6.75 × 6.02×10²³
6.75 moles of F₂O₃ = 4.06×10²⁴ molecules
Thus, 4.06×10²⁴ molecules of F₂O₃ were obtained from the reaction
