The major product of the given reaction has the molecular formula c10h16o3. Draw its structure in the most stable tautomeric form.
Answers
Tautomers are isomers composed of the same atoms but with different electronic and molecular structures. The most stable tautomeric form is attached.
What is tautomery?
Tautomery is a special case of isomery produced by the change in the position of one or more atoms in the molecule. This change in position modifies the molecular electronic distribution, and hence, the molecular structure.
In solution, isomeres called tautomers are in equilibrium, and the constant interconversion is called tautomerization. Both molecules have the same type and quantity of atoms.
In the proposed example, the product has the molecular formula C₁₀H₁₆O₃. Isomeric molecules must have 6C, 16H, and 3O. However, the distribution of these atoms varies, leading to a change in the product molecule structure.
In the attached files you will find an example. You should check if this is the same example as yours.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether it is solid,liquid , gas consists of atoms . Each atom has a nucleus which is contains protons and neutrons and shells in which the electrons revolve.
The protons are positively charged particles and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged particles and hence the atom as a whole is neutral particle and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not change the chemical properties of the substances.

Denatured alcohol vs isopropyl alcohol for cleaning.
Answers
Denatured alcohol and isopropyl alcohol are as similar as they as different. They are both used for cleaning and harmful to people if ingested. But isopropyl seems to be more effective than denatured alcohol. Denatured alcohol has been found to be more toxic and can harm our skin. But when it comes to cleaning, denatured alcohol can be used, but should not be used over isopropyl as it can leave behind residue, especially when it comes to electronic devices. Isopropyl, especially 70%, is more effective because it has more water, which can help it dissolve more slowly, penetrate cells, and kill bacteria.
Imagine that you are a leaf on a plant, and you realize that you are running low on supplies to do your job. You decide to text the roots to set up a delivery. Write a text message conversation between the leaf and the roots that discusses and arranges this delivery.
Be sure to answer these questions in your conversation:
• Which supplies is the leaf running out of? • What are the supplies needed to do? • How will the roots get the supplies from outside the plant? • How will the supplies get from the roots to the leaf?
Answers
The leaves of plants primarily serve to photosynthesize and require water conducted by the root to do so.
Water conduction by the rootAs a leaf of a plant running low on supplies that the root is responsible for, what I will be needing is water.
Thus, I will have to send a text message to the root to supply me with water. The root will respond by asking its foot soldiers (the root hairs) to conduct water into the root.
Once water gets into the root, it enters special cells that are responsible for conducting water inside plants - the xylems. The root sends the water through the xylem and water travels from there to me - the leaf.
Once the water gets to me, I will use it in combination with inorganic carbon (carbon dioxide) to synthesize carbohydrates.

If you have a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2, what is the resulting temperature in K
Answers
The resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.
How to calculate temperature?The temperature of a given gas can be calculated by using the ideal gas law equation:
PV = nRT
Where;
P = pressure V = volume n = number of molesR = gas law constantT = temperatureno of moles of Cl2 = 76.33g ÷ 70.91g/mol = 1.08mol
2.35 × 1.2 = 1.08 × 0.0821 × T
2.82 = 0.088T
T = 2.82/0.088
T = 31.8K
Therefore, the resulting temperature of a closed container that has a pressure of 2.35atm, and a volume of 1.2L, and contains 76.33g Cl2 is 31.8K.

Increasing ions in solution will decrease the pH of a solution, while increasing the. ions in solution will increase the pH of a solution. Fill the Blank
Help me!
Answers
Answer:
Increasing the H+/H3O+ will decrease the pH, while increasing the OH- ions will increase the pH
Explanation:
so pH=-log(H), which means that the smaller H gets to 0, the more the pH rises. The larger the H+ gets, the smaller the pH
if H is 1, then pH is 0
if H is 0.1, then pH is 1
if H is 0.01, then pH is 2
and so on
if H is 0.00000000000001, then the pH is 14
When OH goes up, H goes down, so
if OH is 0.00000000000001, then the ph is 0
if OH is 0.0000000000001, then the pH is 1
and so on
If the OH is 1, then the pH is 14

The enthalpy change of condensation of water is negative and here the entropy change also negative and the process is nonspontaneous.
What is enthalpy change?The enthalpy change of a reaction or a phase change is the change in heat energy absorbed or evolved. The change in enthalpy is dependant on the nature of process as well on temperature of the system.
Condensation of water is the change of its liquid state into solid state. Thus water freezes to form ice. In this process, the system is getting more ordered structure in the solid state and thus, the entropy of the system decreases means the entropy change is negative.
Now, when converting liquid to solid heat is released by the system. Hence, enthalpy change, delta H is negative. A process becomes spontaneous only f its Gibbs energy is negative.
Here we have both negative entropy and enthalpy so make Gibbs energy negative higher temperature is needed.
Condensation of a substances is taking place at very low temperature and thus gibbs energy become positive. Therefore the process is nonspontaneous.

B. The water undergoes a phase transition.
C. The water particles and dye particles exhibit Brownian motion.
D. The water exerts pressure on the container.
Answers
Answer:
C
Explanation:
okay, you need to look at the structures of the particles of matter in the solid, liquid and gas.
particles in a solid are in fixed positions, where they can only vibrate in those positions ( take a look at ice, or rather, a brick)liquids have very small or rather, no spaces between them, but they can slide or rub against each other, like people in a really tight crowd I guessgas particles have very large spaces between them and they move randomly. these exibit what's called brownian motion.since water particles (and all other liquid particles) have negligible spacings and limited movement, that allows the dye particles to move from a region of high concentration to that of a low concentration. the aim for this is for the mixture/solution to reach an equilibrium, that is the mixture must get to a point where all regions have the same concentration of the dye.you can refer to your coursebooks :)

Why do chemist prefer to use kipp’s apparatus for the production of hydrogen sulphide instead of woulf’s bottle??
Answers
Chemist prefer to use kipp’s apparatus for the production of hydrogen sulphide instead of woulf’s bottle because they produce gas without generating heat.
What is kipp's appratus & woulf's bottle?Kipp's appratus and woulf's bottle both are the laborartory appratus and used in the analytical process of any reactions.
Hydrogen sulphide gas will be produced in the laborartory by using both given appratus but we prefer the use of kipp's apparatus because in this apparatus small amount of gas is produced in the controlled heat condition by the reaction between the liquid sulphuric acid and solid iron sulphide.
Hence we prefer kipp's appratus as it produces gas without heat.

least temporarily disrupted from equilibrium. Can you think of a way your body
could respond to restore homeostasis after one of these disruptions? (3 points)
Answers
An example of a temporary disruption from equilibrium is a temperature change, this would be compensated through sweating.
What is equilibrium?This refers to a constant state in which forces are balanced. Inside the body, equilibrium means certain conditions such as the level of oxygen or the temperature are constant.
How is equilibrium lost?This can be lost due to many factors, in the body, this occurs as a result of sudden changes either inside or outside the body. An example of this is sudden temperature changes, for example, if you go out of your house and it is snowing or it is very hot outside.
How is homeostasis or equilibrium restored?The body has specific mechanisms to restore the temperature. For example, if the environmental temperature is too high the body uses sweating to keep a constant temperature.
