During the solvolysis of 2-chloro-2-methylpropane, the production of di-t-butyl ether can be attributed to the removal of a protonated alcohol molecule. This process involves a series of reactions that include nucleophilic substitution and elimination.
In the solvolysis of 2-chloro-2-methylpropane, the chloride ion is displaced by the solvent molecule, such as ethanol, to form a carbocation intermediate. This intermediate can react with another molecule of solvent to form a new compound, such as di-t-butyl ether.
This happens because the t-butyl groups of the carbocation intermediate are sterically hindered and cannot easily be attacked by nucleophiles like water or ethanol. Instead, they can react with another molecule of the solvent to form a new compound.
The reaction sequence for the solvolysis of 2-chloro-2-methylpropane is:
2-chloro-2-methylpropane + ethanol → 2-methylpropene + HCl + ethoxide ion
ethoxide ion + 2-methylpropene → di-t-butyl ether + ethanol

Which of the following is a distinguishing difference between rocks and minerals?
A. Minerals are aggregates of different rocks and elements.
B. Minerals have specific chemical compositions, but rocks do not.
C. Crystals are a type of rock and granite is a type of mineral.
D. Minerals are made of rocks combined in different combinations.
Answer:
B.
Explanation:
Minerals are formed due to chemical composition by rocks are pressured into their formed from dirt and naturally hard things.
The statement that represents a distinguishing difference between rocks and minerals is as follows:
Minerals have specific chemical compositions, but rocks do not.Thus, the correct option for this question is B.
What is the difference between rocks and minerals?A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition, and atomic structure. Rocks are generally made up of two or more minerals, mixed up through geological processes.
Minerals are definitely formed due to chemical composition by rocks being pressured into their formation from dirt and naturally hard things. A rock is an inorganic and a solid naturally-formed substance without any chemical composition or atomic structure.
A mineral is also a solid, inorganic, substance as that like a rock which has a definite crystalline structure as well as chemical composition. Rocks form, break down and move through the rock cycle.
Therefore, the correct option for this question is B.

Consider the data [X] [Y] [Z] initial rate M M M M · s −1 Exp 1 0.30 0.20 0.35 0.210 Exp 2 0.60 0.10 0.70 0.420 Exp 3 0.60 0.20 0.70 0.420 Exp 4 0.60 0.40 0.35 0.105 What is a correct rate law for the reaction?
Answer:
Rate = k [X]⁻¹ [Z]²
Explanation:
[X] [Y] [Z] initial rate M M M M · s −1
Exp 1 0.30 0.20 0.35 0.210
Exp 2 0.60 0.10 0.70 0.420
Exp 3 0.60 0.20 0.70 0.420
Exp 4 0.60 0.40 0.35 0.105
In Experiment 2 and 3 where the concentrations of Y and Z were constant, doubling the concentration of Y had no effect on the rate of the reaction. This means, that the rate of the reaction is zero order with respect to Y.
In experiment 3 and 4, dividing the concentration of Z by 2, causes the rate of the reaction to decrease by 4. This means the rate of the reaction is second order with respect to Z.
In experiment 1 and 4, doubling the concentration of X, causes the rate of the reaction to decrease by half. This means that X has an order of -1 with respect to the rate of the reaction.
The rate expression is given as;
Rate = k [X]⁻¹[Y]⁰[Z]²
Rate = k [X]⁻¹ [Z]²

Answer:
Explanation:
follow the rule of "a weak acid can't make a stronger acid and weak base can't make a stronger base(it's pretty accurate for acid/salt reactions/replacemnts)" the last reactions won't work, but the second to last one will be kbr+pb(no3)2-> kno3 + PbBr2 (this is unballanced.) the first reaction will work. the second one i'm not too sure tbh, but i think it won't work since barium hydroxide's a weak base and if it were to react it would make koh, a super strong base
Answer:
3Ba(OH)2 + 2K3PO4 ----> 6KOH + Ba3(PO4)2
2KBr + Pb(NO3)2 ------> 2KNO3 + PbBr2

bag. What fraction of her money did she have left?
Answer:
1 / 2 of her money would be left
Explanation:
Tammy spent 2/5 of her savings on a watch. She then spent 1/6 of the remainder on a bag. What fraction of her money did she have left?
Taking the question bits by bit;
Tammy spent 2/5 of her savings on a watch
Amount Spent = 2/5
Remainder = 1 - 2/5 = 3/5
She then spent 1/6 of the remainder on a bag
Amount Spent = 1/6 * 3/5 = 1/2 * 1/5 = 1 /10
Total amount spent = 2/5 + 1 /10 = (4 + 1 ) / 10 = 5 / 10 = 1 / 2
Amount left = 1 - 1 /2 = 1 / 2

An iron loses electrons. State the type of charge it will end up with
write in your own words
Answer:
Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic

6. El oxígeno gaseoso se calienta a presión constate de 50 °C a 300 K. Se conoce que inicialmente el volumen del sistema era de 1,3 litros. ¿Cuál es el volumen final del sistema?
Answer:
El volumen final del sistema es 1.2L
Explanation:
La ley de Charles establece que el incremento de la temperatura de un gas produce un incremento en el volumen directamente proporcional cuando la presión permanece constante. La ecuación es:
V₁/T₁ = V₂/T₂
Donde V es volumen y T temperatura absoluta de un gas en 1, el estado inicial y 2, su estado final.
Reemplazando:
V₁ = 1.3L
T₁ = 50°C + 273.15K = 323.15K
V₂ = Incógnita
T₂ = 300K
1.3L/323.15K = V₂/300K
1.2L = V₂
El volumen final del sistema es 1.2Lvery urgent
1. Describe an experiment to show the chemical effect of electric current.
2. State three conditions necessary for combustion
3. Describe all that you observe when a piece of iron is placed in copper sulphate solution for a
few minutes.
Explanation:
STEP 1- Take two iron nails.
STEP 2- Clean it with sand paper.
STEP 3- Wrap copper wire around both the nails. And connect the other end to the battery terminal.
STEP 4- Take water in beaker and little amount of salt in it or a few drpos of sulphuric acid in it.
STEP 5- Immerse the nails in the solution.
STEP 6- Observe the nails carefully. You can see bubbles of gases coming out from water near nails.
When, electeric current is passed through water gases like hydrogen and oxygen are evolved.
2.Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.
When iron is placed in Copper sulphate solution, the iron is coated with a brown coloured substance "copper" and CuSo4 solution changes from blue to light green. This is due to iron displaces copper as it is more reactive than copper.
