Yes, Fe(s)+CuSO4→FeSO4(aq)+Cu(s) is a redox reaction. The reducing agent is Fe(s), while the oxidizing agent is CuSO4.
Oxidation-reduction reaction (redox)Oxidation-reduction reaction is the type of reaction in which electrons are transferred from one element to another. A compound or an element either gains are looses an electron in redox reactions.
Fe(s)+CuSO4→FeSO4(aq)+Cu(s)
From the equation above, Fe(s) is the reducing agent because it gives away 2 electrons and undergoes oxidation reaction.
From the equation above, CuSO4 is an oxidizing agent because it gives oxygen to Fe(s) and undergoes a reduction reaction.
Therefore, the reducing agent is Fe(s), while the oxidizing agent is CuSO4.

How was this organism transported to a new ecosystem in the u.s.
Answer:
ExplaIf the organism was transported to a new ecosystem in the USA, this species will be an invasive species, which will reproduce more, and will not have a specific predator, which may bring an imbalance to the ecosystem.
What are Invasive Species?
Invasive Exotic Species or, simply, Invasive Species is defined as an exotic species that proliferates without control and starts to pose a threat to native species and to the balance of ecosystems that it occupies and transforms in its favor. It can even pose a risk to people.
With this information, we can conclude that caution is needed when introducing a new species into a new ecosystem.

You will be performing many dilutions in this experiment. If John adds 17.51 mL of 6M HCl to 6.36 mL of distilled water, what is the final concentration, in M, of HCl
The molarity of the solution decreases on dilution by adding distilled water. The molarity of the solution of 17.51 ml , 6 M HCl when added to 6.36 ml is 4.4 M.
What is molarity ?Molarity is a common term used to express the concentration of a solution. The molarity of a solution is the ratio of the number of moles of solute to the volume solution in liter.
If a solution of volume V1 ml with M1 molarity is diluted to V2 ml of M2 molarity, then, the relation between the two concentrations is written as:
M1 V1 = M2 V2.
given, M1 = 6 M
V1 = 17.51
the volume after the addition of 6.36 ml water, v2 = 17.51 + 6.36 = 23.78 ml
then M2 = M1 V1/V2
M2 = 6 M × 17.51 ml/ 23.78 ml
= 4.4 M.
Therefore, the molarity of the solution after dilution is 4.4 M.

An electrochemical cell is based on these two half-reactions and their given standard reduction potential values:
Ox: Sn(s)→Sn2+(aq,1.60molL−1)+2e−E∘anode=−0.14(V)
Red: ClO2(g,0.220bar)+e−→ClO−2(aq,1.60molL−1)E∘cathode=0.95(V)
Compute the cell potential at 25 ∘C .
The potential of the electrochemical cell is 0.03 V.
What is an electrochemical cell?An electrochemical cell is a cell that produces chemical energy from a spontaneous chemical process. Let us recall that cell potential can be obtained from; Ecell = 0.0592/n log K
The cell equation is;
Sn(s) + ClO2(g) ----> Sn^2+(aq) + ClO^2-(aq)
Hence;
K = (1.60) (1.60)/(0.220)
K = 11.6
Therefore;
Ecell = 0.0592/2 log (11.6)
= 0.03 V

You need to make a 1:4 dilution of dye in water so that the total volume in test tube one is 60 ml.
From the solution you made in test tube one, you need to make a 1:5 dilution into test tube two so that the total volume is 15 ml.
Find Transfer Volume
Find Diluent
Find TDF
In the serial dilution for the preparation of the dye, the total dilution factor is 1/20
What is dilution of solution?Dilution is the process of preparing solutions of lesser concentration from a more concentrated solution.
In test tube 1:
Total volume = 60 mL
Dilution factor = 1:4
1 parts stock solution is required for every four parts diluent
Total parts = 5
volume of diluent = 4/5 × 60 mL = 48 mL
48 mL of diluent is added to 12 mL of stock solution to prepare the solution in test tube 1.
In test tube 2:
Total volume = 15 mL
Dilution factor = 1:5
1 parts stock solution is required for every five parts diluent
Total parts = 6
volume of diluent = 5/6 × 15 mL = 12.5 mL
12.5 mL of diluent is added to 2.5 mL of stock solution from tube 1 to prepare the solution in test tube 2.

Which phenomenon best explains the miscibility of heptane (CH3CH2CH2CH2CH2CH2CH3) in pentane (CH3CH2CH2CH2CH3)
The phenomenon that best explains the miscibility of heptane in pentane is that both are non-polar compounds.
Solubility of compoundsSolubility is defined as the ability of a solute or substance to dissolve in a given solvent and at a particular temperature.
Heptane is a straight-chain alkane hydrocarbon that contains 7 carbon atoms. It is a non polar solvent.
Pentane is also a straight-chain alkane hydrocarbon that contains 5 carbon atoms. It is also a non- polar solvent.
Both pentane and heptane are non-polar because the atoms in their molecules share electrons equally. They are able to dissolve each other because they are alike.
