the following reaction gives a product with the molecular formula c4h8o2. draw the structure of the product.
The following reaction gives a product with the molecular formula C₄H₈O₂. The diagram of the structure of the product can be seen in the image attached below.
The reaction between C₂H₂(ONa)₂ and C₂H₄Br results in the formation of the product C₄H₈O₂ and 2NaBr.
This reaction undergoes an SN₂ mechanism since there is no stable carbocation formed. In the reaction -O⁻Na⁺ attacks the ortho position in C₂H₄Br to form C₄H₈O₂.
In SN₂ mechanism is a nucleophilic substitution reaction where one bond is formed while another one is broken simultaneously.
The mechanism for the reaction can be seen in the image attached below.

In a population, exponential growth
can lead to a lack of resources,
which causes the population
numbers to decline. This is an
example of:
A. a positive feedback loop
B. a negative feedback loop
C. the first law of thermodynamics
D. the second law of thermodynamics
о
Exponential growth can lead to decreasing the population size, which represents an example of a NEGATIVE feedback loop. This control mechanism (negative feedback) is common in nature.
Negative feedback is a homeostatic self-regulatory process by which the output of a given system is fed back in order to reduce its internal fluctuations.
In a negative feedback, an amplified output from the system (e.g., in this case, a sudden increased population size) leads to its self-inhibition.
This control mechanism (negative feedback loop) helps to maintain the homeostatic balance of the entire system in order to reach a set point.

What is true of a saturated solution?
Answer:
A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. If any more NaCl is added past that point, it will not dissolve because the solution is saturated.
This atom tends to gain an electron in its outer shell so that there are a total of 8 electrons.

for the sn1 reaction, draw the major organic product, identify the nucleophile, substrate, and leaving group, and determine the rate limiting step.
C4H9OH is the substrate, Br- is the nucleophile and H2O is the leaving group.
In an SN1 reaction, the rate limiting step is the formation of the carbocation. The carbocation is formed as water which is the leaving group departs. After the leaving group departs, the nucleophile (Br-) attacks to yield the major organic product. The protonation of the -OH group is the first step in the reaction.
It then follows that, C4H9OH is the substrate, Br- is the nucleophile and H2O is the leaving group.

Multiply the mass by the % written as a decimal and add the result.
426X0,11 + 417X 0.89 = 417.99 or 418
check 90% is. 417 only 10% 426

How many moles of ions are there in 1 mole of iron (III) oxide, Fe2O3?
Answer:
So one mole of Fe2O3 contains two moles of Fe3+ ions.
Explanation:
As there is an internal mole ratio of 2:3
It means that there are 2moles of iron within every mole of iron(III) oxide.
Iron III oxide is an ionic compound composed of Fe3+ ions and O2- ions. According to the formula, there are three O2- ions for every two Fe3+ ions.
Extra:
One 'unit' of Fe2O3 has two Fe3+ ions and three O2- ions, hence a dozen Fe2O3 contains two dozen Fe3+ ions and three dozen O2- ions, and a mole Fe2O3 contains two moles Fe3+ ions and three moles O2- ions.
