Write a description of your dream car by using powerful adjectives. Write about 100-120 words
Answer:
It was a cold December night shortly after dusk, a likely setting for an event that would prove to be life altering. As fate would have it, this would be the night that I lost the material possession that truly meant the most to me. I would lose the one thing that gave me much pride and joy and excitement. I often think back and liken us to a newlywed couple, for we had only been together for 18 months and were still very much honeymooning. It was a night, a moment, that even now scoffs and mocks me as I travel thither and yonder with her replacement. But she can never be truly replaced and to call my current fix a replacement seems like a sort of blasphemy.
I called her my Blue Angel. That's right! She was a brand new 1999 Atlantic blue Ford Mustang fully equipped with white racing stripes on each side, dark window tint, a rear spoiler, and a post-factory sound system that I installed personally just to complete the "dream ride" effect. We met on April 24, 1999,when my parents introduced us and told me she was all mine as a reward for graduating high school as valedictorian. And what a reward she turned out to be. We went everywhere together. I took her out to eat. When I'd go play ball somewhere, she went with me. Every day from April 24, 1999, to December 22, 2000, we were together. We were bonding in a way a young man can bond with no other, and there truly was no other for me. Other guys had bigger trucks and faster cars, but where my Blue Angel was lacking in size and power, she more than made up for in pure, unadulterated, raw emotion, She never let me down; she was always looking her best and never longing for attention from me or any of the other countless admirers and fans she won over for...

What can you say about the effect of sulfuric acid on the reaction between the alcohol and carboxylic acid?
Answer:
It provides hydrogen ions to favor the formation of ester.
Explanation:
Hello!
In this case, since the reaction between and alcohol and a carboxylic acid yields an ester and water as an organic acid-base neutralization reaction, represented via:
[tex]R_1-OH+R_2COOH\rightleftharpoons H_2O+R_2COO-R_1[/tex]
As you can see, this reaction is at equilibrium because the ester is able to come back to the initial reactants, it means that the addition of hydrogen ions favor the reaction towards the formation of more ester, effect that is attained via the addition of sulfuric acid, which acts as a catalyst in this reaction because it provides the hydrogen ions, this reaction needs.

A student needs to use the metric system while measuring the length of a box. Which units should he use?
AWNSER FAST PLEASEEE
Answer:
Centimeters or milimeters.
Explanation:
The answer depends on the size of the box.
The metric system base unit for length is the meter. Centimeters and milimeters are thus also part of the metric system.
If the box is a "regular-sized" box that we use to put stuff in (books, presents, etc), then centimeters would be the most appropiate.
If we're talking about those tiny boxes that are printed on paper (for example in some notebooks) then milimeters would be the most appropiate.

The hybrid orbital set used by the central atom in no3- is_____ and why?
a. sp
b. sp3
c. SP2
d. sp3d2
e. sp3d
Answer:
c. SP2
Explanation:
The image in the diagram below shows the structure of NO₃⁻
Nitrogen is the central atom with the electronic configuration of 1s² 2s² 2p³.
So in its outermost shell, it has 3 electrons and the hybridization is sp²
However,
According to Hund's rule:
The ground state of Nitrogen is;
1s² 2s² 2p³
↑↓ ↑ ↑ ↑ ↑
At the excited state when it is attached to 3 different oxygen ions, we have:
1s² 2s² 2p⁵
O⁻ ---> ↑↓ ↑↓ ↑↓ ↑↓ ↑
1s² 2s² 2p⁵
O⁻ ---> ↑↓ ↑↓ ↑↓ ↑↓ ↑
1s² 2s² 2p⁴
O⁻ ---> ↑↓ ↑↓ ↑↓ ↑ ↑
Thus, the 3 sp² orbital lies in a plane and form 3 N - O σ- bond and one π- bond.

In the reaction of silver nitrate with copper metal, metallic silver comes out of solution, and the solution turns blue. This as a ________ reactio
Answer:
Single displacement reaction.
Explanation:
Hello!!
In this case, since the reaction between silver nitrate and copper metal is:
[tex]2AgNO_3(aq)+Cu(s)\rightarrow 2Ag(s)+Cu(NO_3)_2(aq)[/tex]
As silver was forming silver nitrate, due to the presence of copper, which has the capacity to displace silver out of the salt, we notice the formation of solid silver and a resulting copper (II) nitrate which is blue in aqueous solution.
Therefore, this is a single displacement reaction, because the the lonely copper displaced the silver.

A solution is made by adding 5.01 g of iron sulfate to 75.3 g of water. What is the mass percentage of iron sulfate in this solution?
Answer:
6.24 % of FeSO₄
Explanation:
Solute mass: 5.01 g of FeSO₄
Solvent mass: 75.3 g of water
Solution mass = solute mass + solvent mass
5.01 g + 75.3 g = 80.31 g
We can apply a rule of three. Mass percentage means the mass of solute which is contained in 100 g of solution. Then,
In 80.31 g of solution we have 5.01 g of solute
In 100 g solution, we may have (5.01 . 100)/ 80.31 = 6.24 g of solute.
This is the mass percentage: 6.24%

Which of the following best explains how the results of Rutherford’s experiment affected Thomson’s widely-accepted atomic model?
Explanation:
Thomson's suggested the plum pudding model of the atom in which the atomic space is made up of electrons surround by positive charges.
Rutherford in his gold foil experiment revised the plum pudding model of the atom;
He discovered that most of the alpha particles passed through the foil while a few of them were deflected back. To explain this observation, he suggested the atomic model of the atom. In this model, an atom is made up of a small positively charged center where nearly all the mass is concentrated. Surrounding the nucleus is the extranuclear part made up of electrons.calculate the (m/v) of nacl of a solution made by diluting 25.0 ml of a 7.50 (m/v)% NaCl solution to a total volume of 75.00 ml
Answer:
2.5%
Explanation:
Given
M1 = 7.50%
M2 = ?
V1 = 25.0mL
V2 = 75.00mL
M1V1=M2V2
7.5x25=M2x75
M2=2.5%
The NaCl of a solution made by diluting 25.0 ml of a 7.50 (m/v)% NaCl solution to a total volume of 75.00 ml is 2.5 (m/v)%.
What is solution?Solution is defined as a continuous variation of two or more substances in their relative proportions up to what is known as the limit of solubility. A solute is the name for the substance that dissolves to create a solution. A solvent is the material that a solute will dissolve in. Sugar is the solute and water is the solvent in a sugar-water solution.
To calculate the molarity of NaCl
We use M1V1 = M2V2
Given M1 = 7.50 (m/v)%
V1 = 25.0 ml
V2 = 75.0 ml
M2 = M1 V1 / V2
M2 = 7.50 x 25.0 / 75.0
M2 = 2.5 (m/v)%
Thus, the NaCl of a solution made by diluting 25.0 ml of a 7.50 (m/v)% NaCl solution to a total volume of 75.00 ml is 2.5 (m/v)%.

Determine the molarity of a solution prepared by dissolving 0.198 g of "KHP" (C8H5O4K) in enough water to make 125 mL of solution.
When the solution is found and titrated with aqueous sodium hydroxide, the endpoint is reached after the addition of 27.80 mL of base solution. How many moles of NaOH reacted? What is the concentration of the NaOH?
Answer:
0.007756M KHP; 0.0009695 moles NaOH reacts; 0.03488M NaOH.
Explanation:
Potassium hydrogen phthalate, KHP, is a salt used as standard to determine concentration of basic solutions as NaOH solutions.
To find molarity of the KHP solution we need to convert mass of KHP to moles and divide this in 125mL = 0.125L:
Moles KHP -Molar mass: 204.22g/mol-:
0.198g * (1mol / 204.22g) = 0.0009695 moles KHP
Molarity:
0.0009695 moles KHP / 0.125L = 0.007756M KHP
NaOH reacts with KHP as follows:
NaOH + KHP → Na⁺ + KP⁻ + H₂O
That means 1 mole of NaOH reacts per mole of KHP, that means moles of NaOH that reacts are = Moles of KHP added:
0.0009695 moles NaOH reacts
In 27.80mL = 0.02780L the NaOH was contained. Molarity is:
0.0009695 moles NaOH / 0.02780L =
0.03488M NaOH
Moles of NaOH added will be "0.034".
According to the question,
→ [tex]Molarity = \frac{Number \ of \ moles}{Volume}[/tex]
By substituting the values, we get
[tex]= \frac{0.198}{204}\times \frac{1000}{125}[/tex]
[tex]= 0.0077 \ M[/tex]
Let,
The number of moles added be "[tex]M_2[/tex]".Now,
→ [tex]M_1 V_1 = M_2 V_2[/tex]
→ [tex]0.0077\times 125=M_2\times 27.8[/tex]
→ [tex]M_2 = 0.034 \ moles[/tex]
Thus the above answer is appropriate.
