Answer:
What is filteration:Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. ... In some processes used in the production of chemicals, both the fluid filtrate and the solid filter cake are recovered.
When do we use it:Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.
In order to separate a salt-water mixture,should a student use filtration:The mixture can be separated by filtration, by dissolving the mixture in water. Salt will dissolve in the water, whereas sand will not.

You need 2 pieces of bread, 1 tablespoon of peanut butter and 2 tablespoons of jelly to make a
sandwich. If you have 10 pieces of bread, 4 tablespoons of peanut butter and 20 tablespoons of jelly,
what is the limiting reactant?
Answer:
peanut butter
Explanation:
because you have 10 pieces of bread, 4 tbs of peanut butter, and 20 tbs of jelly, meaning you can make 5 sandwwitches with the bread, 4 sandwitches with the peanut butter, and 10 sandwitches with the jelly. so you dont have enough peanut butter to make all the sandwitches
According to the given scenario, If one have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, the limiting reactant will be peanut butter.
What is a limiting reactant?
The reactant that gets consumed first in a chemical reaction and result in limiting the formation of product is referred to as a limiting reactant.
According to the given scenario, the quantity of peanut butter will get consumed first so it will act as a limiting reactant.
Thus, If one have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, the limiting reactant will be peanut butter.

Where glucose is broken down into smaller molecules to produce energy. The second part of the process takes place in the
Answer:
Mitochondria
Explanation:
Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.
The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of 3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.
In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.
which substance is reduced ?
Cl^2 +2KBr= 2KCl + Br2
Answer:
Initially Br is in -1 oxidation state and Cl in 0 oxidation state. Finally Cl is in -1 o.s. and Br in 0.
This means that Br has oxidised from -1 to 0 and Cl is reduced from 0 to -1.
KBr is reducting agent as it helps Cl to reduce.
Cl2 is oxidising agent as it helps Br to oxidise.

How many L of a 7.5 H2SO4 stock solution would you need to prepare a dilute solution 100 L of 0.25M H2SO4
Answer:
3.33 L
Explanation:
We can solve this problem by using the equation:
C₁V₁=C₂V₂Where the subscript 1 refers to one solution and subscript 2 to the another solution, meaning that in this case:
C₁ = 0.25 MV₁ = 100 LC₂ = 7.5 MV₂ = ?We input the data:
0.25 M * 100 L = 7.5 M * V₂V₂ = 3.33 LThus the answer is 3.33 liters.
Is there a solution for the impacts overfishing?
Answer:
The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.

2. How much heat is needed to convert 2.7 moles of ethanol at its boiling
point from liquid to vapor?
Answer:
así que busca, pero la respuesta está en por cierto Explanation:
The quantity of heat needed to convert 2.7 moles of ethanol at its boiling point from liquid to vapor is 104.49 kJ
From the question,
We are to calculate the heat needed to convert 2.7 moles of ethanol from liquid to vapor.
Using the formula
Q = n × ΔHvap
Where Q is the quantity of heat
n is the number of moles
and ΔHvap is the enthalpy of vaporization
From the given information,
n = 2.7 moles
and
ΔHvap of ethanol = 38.7 kJ/mol
Putting the parameters into the formula, we get
Q = 2.7 × 38.7
Q = 104.49 kJ
Hence, the quantity of heat needed to convert 2.7 moles of ethanol at its boiling point from liquid to vapor is 104.49 kJ

According to the reaction below, how many grams of KCl (potassium chloride) can be formed from 106.35 g of chlorine with excess potassium?
2K + Cl2 ---> 2 KCl
Answer:
225 grams
Explanation:
Given: K + Cl₂ => 2KCl
excess 106.35g ?grams
Suggestion: For stoichiometry problems, convert all data given to moles and solve by ratio based on given equation and relative data given. After working in terms of moles, convert to dimension specified in problem.
moles Cl₂ = 106.35g / 70g/mol = 1.52 moles
From balanced equation:
1mol Cl₂ => 2mol KCl
1.52 mol Cl₂ => ?(mol KCl)
∴moles KCl produced = 2 mol KCl x 1.52 mol Cl₂ / 1 mol Cl₂ = 3.04 mol KCl
Grams KCl = 3.04 mole x 74 grams/mole = 225 grams
