There are total three laws of newtons, first law of newtons, second law of newton and third law of newton. Therefore, when a golf club is subjected to an imbalanced force, its velocity changes, which is according to newton’s second law.

According to Newton's Second Law of Motion, acceleration (gaining speed) occurs when a force acts on a mass (object). Riding a bicycle is a great example of this rule of motion in action. The mass is represented by your bicycle. The force is generated by your leg muscles pulling on the pedals of your bicycle.

The ball remains balanced on the tee due to the balanced forces of gravity downhill and upward. Force equals mass multiplied by acceleration (f=ma). When a golf club is subjected to an imbalanced force, its velocity changes.

Therefore, when a golf club is subjected to an imbalanced force, its velocity changes, which is according to newton’s second law.

Explanation:

However, when the carboxylic acids and esters put together are obtained, the procedure below can be followed in drawing and naming them.

For carboxylic acid,

1) it should be noted that the functional group here is -COOH which is drawn as -C = OH

      |

     OH

2) The carbon of the functional group is included among the carbon to be counted when naming the structure. For example, the compound below is propanoic acid.

CH₃CH₂COOH - As you can see that there are 3 carbons linked chain there.

3) As can be seen in (2) above, the suffix "oic" is used to name carboxylic acids

4) The carbon chain here is saturated (meaning there is no double or triple bond within the carbon chain)

Example of a structure of carboxylic acid is

H₃C - CH₂ - CH₂ - C = OH

                              |

                             OH

The structure above is a butanoic acid

For ester

1)The functional group here is -COO- . which can be drawn as

- C = O

   |

  O -

(meaning one oxygen atom is double bonded to the carbon and the other oxygen atom is bonded to another carbon chain)

2) The alkyl group attached to the oxygen atom is first of all mentioned before the carbon chain attached from the left is mentioned. For example, CH₃CH₂CH₂COOCH₂CH₃ is ethyl butanoate

3) As seen from (2) above, the suffix "oate" is used to end the name of esters

4) As also seen from (2) above, the carbon of the functional group is also included while counting the carbon chain of the parent name (butanoate).

5) The carbon chains here are also saturated.

Example of this ester is

CH₃CH₂C = O

              |

             O - CH₂CH₃

The name of this compound is ethyl propanoate

Explanation:

Answer:

Methyl propyl ether protonates at oxygen, and this makes the oxygen a good leaving group for  [tex]SN2[/tex] attack by iodide ion which is a good nucleophile.

We are aware that  [tex]SN2[/tex] prefers 1 degree carbocation and here both methyl , propyl group is 1 degree.  

So we have two possible carbon atoms to react with iodide which are methyl group and  propyl group. They will react with iodide at similar rates, and so there is no great preference of one over the other.

As [tex]HI[/tex]  is present in excess the hydrogen of [tex]HI[/tex]  protonates the oxygen which leads to cleavage  that can happen on both sides either methyl or propyl side leading to different products.

The reaction proceeds in the manner

[tex]CH3-O-CH2CH2CH3[/tex]  + [tex]HI[/tex]   → CH3I + CH3CH2CH2OH

OR

[tex]CH3-O-CH2CH2CH3[/tex] + [tex]HI[/tex]   → CH3OH + CH3CH2CH2I

Answer:

[tex]m_{CO2}=8.33gCO2[/tex]

Explanation:

Hello.

In this case, since the chemical reaction is:

[tex]C_7H_5N_3O_6(s)+\frac{21}{4} O2(g)\rightarrow 7CO_2(g)+\frac{3}{2} N_2(g)+\frac{5}{2} H_2O(l)[/tex]

Thus, since we have the initial moles of TNT:

[tex]n_{TNT}=25.7g*\frac{1mol}{227.13g} =0.113mol[/tex]

And the initial moles of oxygen given the ideal gas equation:

[tex]n_{O_2}=\frac{6.93atm*0.5L}{0.082\frac{atm*L}{mol*K}*298K}=0.142molO_2[/tex]

Given the 1:7 mole ratio between TNT and carbon dioxide and the 21/4:7 mole ratio between oxygen and carbon dioxide, we compute the yielded moles by each reactant:

[tex]n_{CO_2}^{by\ TNT}=0.113molTNT*\frac{7molCO_2}{1molTNT}=0.791molCO_2\\\\ n_{CO_2}^{by\ O_2}=0.142molO_2*\frac{7molCO_2}{21/4molO_2}=0.189molCO_2[/tex]

Thus, since oxygen yields less moles of carbon dioxide than TNT, we infer it is the limiting reactant, therefore, the produced mass of carbon dioxide is:

[tex]m_{CO2}=0.189molCO2*\frac{44.01gCO2}{1molCO2}\\\\m_{CO2}=8.33gCO2[/tex]

D. Electron pairs repelling each other push atoms apart

Explanation:

Hope this helps :) I just got it wrong on ap3x so I'm sure this is right

The VSEPR theory explain molecular shape by stating that the Electron pairs repelling each other push atoms apart. Hence, Option (D) is correct

Valence shell electron pair repulsion (VSEPR) theory, is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.

It is also named the Gillespie-Nyholm theory after its two main developers, Ronald Gillespie and Ronald Nyholm.

Therefore, The VSEPR theory explain molecular shape by stating that the Electron pairs repelling each other push atoms apart. Hence, Option (D) is correct.

Answer: Sulfuric Acid

Explanation: correct on edg

Answer:

Sulfuric Acid

Explanation:

correct on edg

Answer:

see the pic for more detail

The pH of the solution after the titration has been 1.318.

pH can be defined as the negative logarithmic values of the hydrogen ion concentration in the solution.

The remaining acid solution has been responsible for the pH of the solution.

The moles of acid can be given by:

Moles = Molarity × Volume

Moles of acetic acid = 0.1 M × 0.025 L

Moles of acetic acid = 0.0025 moles

Moles of NaOH = 0.1 M × 0.01 L

Moles of NaOH = 0.001 moles.

By the neutralization reaction, the moles of acid remaining has been:

Mole of acid remaining = Moles of acid - Moles of NaOH

Moles of acid remaining = 0.0025 - 0.001

Moles of acid remaining = 0.0015 moles.

The hydrogen ions liberated by the acetic acid have been equivalent to the moles of acetic acid.

Thus, the moles of hydrogen ions = 0.0015 mol.

The concentration of hydrogen ions has been:

Molarity = [tex]\rm \dfrac{moles}{volume\;(L)}[/tex]

Molarity of hydrogen ion = [tex]\rm \dfrac{0.0015}{0.025\;+\;0.01\lL}[/tex]

Molarity of the hydrogen ion has been = 0.0428 M.

The pH of the solution has been:

pH = -log [Hydrogen concentration]

pH = -log (0.0428)

pH = 1.318.

The pH of the solution after the titration has been 1.318.
