How many molecules are there in 5.9 moles of NaCl?
The number of molecules= 3.55 x 10²⁴
Further explanationGiven
5.9 moles of NaCl
Required
The number of molecules
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
So for 5.9 moles :
= 5.9 x 6.02 x 10²³
= 3.55 x 10²⁴

Suppose you make your living fishing for lobster. You and everyone else are free to set out as many traps as you like. As more and more traps are set up, however, fewer and fewer lobsters are caught. Soon, lobster catches are too small to support your families. A meeting is coming up where you and your fellow lobster fishers will present possible solutions to this problem. What will you propose to combat this tragedy of the commons and restore the fishery?
Explanation and Answer:
This is an opinion based question and there could be many different responses these are just examples of solution to restore the fishery:
-limiting the season during which lobsters can be caught this allows the population to reproduce itself gradually but maintaining it in control
-limiting the amount of lobster that can be caught therefore again letting the population increase

Identify a human activity that impacts the land negativaly. Then describe a positive action that can help reduce the effects caused by the activity
Answer:
Pollution
•The number of trips one takes in a car should be reduced.
•Reduce or eliminate fireplace and wood stove use.
•Burning leaves, trash, and other materials should be avoided.
•Using gas-powered lawn and garden equipment should also be avoided.
In an ecosystem, pollution is a human activity that impacts the land negatively.Minimum use of vehicles and emission of smoke can help reduce the effects caused by the activity.
What is an ecosystem?An ecosystem is defined as a system which comprises of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through means of nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the ecosystem .Living organisms also influence the quantity of biomass which is present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

There are 5.5 moles of Argon gas in tank
Further explanationGiven
122.6 liters of Argon gas
Required
The number of moles
Solution
Assume at STP
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
So for 122.6 L :
= 122.6 L : 22.4 L
= 5.47 moles ≈ 5.5 moles
If you have 40.0 g HCl and 40.0 g NaHCO3, do you have the same number of moles of each?
They both have a different number of moles
Further explanationGiven
40 g HCl
40 g NaHCO3
Required
moles
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
n = mass : molar mass
So the moles of a compound are affected by its molar mass (inversely proportional)
The larger the molar mass (of the same mass), the smaller the moles
molar mass HCl = 58.5 g/mol
molar mass NaHCO3 = 84 g/mol
mol HCl :
= 40 : 58.5
= 0.684
mol NaHCO# :
= 40 : 84
= 0.476

Enzymes are catalysts in living things, including in the molds and bacteria that cause the spoiling reactions that decompose food. Use your knowledge of reaction rates to explain why food doesn’t rot as fast when it is covered and refrigerated. For full credit identify two different factors and explain how they are slowing down the reaction.
I already have that the cold temperature will slow down the reaction, and I'm sure the covering has something to do with it, but I'm not sure what the factor could be. I think my answer has to be one of the factors we learned in class (which are catalyst, concentration, surface area, and temperature).

How do the two desalination processes differ from the atmospheric water generator in terms of where the processes can be used?
Answer:
Water Desalination Processes. Water desalination processes separate dissolved salts and other minerals from water. Feedwater sources may include brackish, seawater, wells, surface (rivers and streams), wastewater, and industrial feed and process waters. Membrane separation requires driving forces including pressure (applied and vapor)
Explanation:
Salinized water cannot be consumed by humans, but it can be converted into freshwater, which has a variety of purposes. Desalination is the procedure, and it is being employed increasingly frequently all over the world to supply people with the freshwater they require.
What is desalination process?Desalination is the procedure used to remove the dissolved mineral salts from water. Currently, one of the most popular methods for obtaining fresh water for use in agriculture or human consumption when applied to seawater.
When seawater evaporation occurs, salt is left behind, and clouds are formed, which eventually result in rain. Da Vinci realised that it was easy to obtain using a still. Aristotle had observed that seawater would evaporate and condense into fresh water.
Seawater desalination was mostly utilised on ships and submarines over the next centuries to supply the crew with fresh water during lengthy voyages. Nevertheless, this method was not widely accessible until the industrial revolution and, more specifically, until the creation of desalination facilities.

Benjamin Franklin invented the lightning rod as a way to prevent lightning from causing damage to property or people. Use this same idea to construct a device that can protect a person from static charge buildup in their body as they run on a treadmill. Consider that the person wears rubber-soled shoes that rub on the treadmill's running surface, which generates static charges that build up in their body. When the person finishes her workout, she can receive an unpleasant shock when she steps off the treadmill and touches an object that suddenly discharges all of that charge. How can you apply Ben Franklin's idea of a lightning rod to solve this problem? Create a sketch showing how your shock protection system works. Your sketch should be labeled and clearly indicate how the excess static charge in a human body is discharged by the system you design. 12 f(x) (1000) 1 G
Answer:
By 1750, in addition to wanting to prove that lightning was electricity, Franklin began to think about protecting people, buildings, and other structures from lightning. This grew into his idea for the lightning rod. Franklin described an iron rod about 8 or 10 feet long that was sharpened to a point at the end.

If 4.5 moles of AlCl3 were made, how many moles of CuCl2 were used?
Answer:
6.75 moles of CuCl₂ were used
Explanation:
Given data:
Number of moles of AlCl₃ formed = 4.5 mol
Number of moles of CuCl₂ used = ?
Solution:
Chemical equation:
3CuCl₂ + 2Al → 2AlCl₃ + 3Cu
Now we will compare the moles of CuCl₂ and AlCl₃
AlCl₃ : CuCl₂
2 : 3
4.5 : 3/2×4.5 = 6.75
6.75 moles of CuCl₂ were used.
Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of _______ and ______. (called Nuclear fusion)
Answer:
Hydrogen atoms fuse together to form helium atoms. This releases a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
Explanation:
Nuclear Fusion is the Nuclear process in which the energy is produced when two lighter elements are collided together which are having some kinetic energy in them after that the two lighter nuclei will fuse together into a single heavier nuclei. This is opposite to what happens in Fission process in which the breaking up of atomic specie happens.
Both Nuclear Fission and Nuclear fission occurs with the release of massive amount of energy.
There are conditions for nuclear fusion to happens like, it requires 100 million's kelvin of temperature, also fusion will occur when the pressure is very high because increased pressure will result into squeezing of the atomic specie and hence they will fuse.
When the Hydrogen atom fuse together to form helium atoms. This release a huge amount of energy in the form of Kinetic energy of the alpha particle and Electromagnetic radiation.
