Answer:
The reaction rate is 12times faster in SN2 reaction .
Explanation:
For SN2 reaction ,
r= k [1-iodopropane] [NaOH] -(1)
Rate depends upon reactants if we make change in concentration of reactants it will directly change the reaction.
Now concentration of 1- iodipropane is quadruple
And concentration of NaOH is tripled
\(r_n_e_w\) = k 4 × [1-iodopropane] × 3 × [NaOH]
\(r_n_e_w\) = 12 (k[1-iodopropane][[NaOH])
\(r_n_e_w\) = 12 ( r) putting r from ( 1)
Hence , the reaction rate is 12 times faster in SN2 reaction

The density of carbon dioxide is 1.98kg/m^3. Express the density of CO2 in grams/cm^3
Answers
Answer:
Explanation:
We know that,
1 kg = 1000 g
1 m = 100 cm
Therefore
1 m^3 = 1000000 cm^3
Therefore in order to convert the density of CO2 in grams/cm^3
1.98 kg/m^3 = (1.98 × 1000) / 10^6
=1.98 × 10^(-3) grams/cm^3.

An element has 2 stable isotopes. One has 13 amu and 1.07% abundant . The second has 12 amu and 98.93% abundant. What is the average atomic mass of the element
Answers
The average atomic mass of the element is 12.0107 amu.
To calculate the average atomic mass of the element in question, we can use the following formula:
average atomic mass = (mass of isotope 1 x abundance of isotope 1) + (mass of isotope 2 x abundance of isotope 2)
where "mass of isotope 1" is the mass of the first stable isotope (13 amu in this case), "abundance of isotope 1" is the percentage of that isotope in the element (1.07% in this case), "mass of isotope 2" is the mass of the second stable isotope (12 amu in this case), and "abundance of isotope 2" is the percentage of that isotope in the element (98.93% in this case).
Substituting the given values in the formula, we get:
average atomic mass = (13 amu x 1.07%) + (12 amu x 98.93%)
average atomic mass = (0.1391 amu) + (11.8716 amu)
average atomic mass = 12.0107 amu
Therefore, the average atomic mass of the element is 12.0107 amu.
This means that on average, one atom of this element weighs 12.0107 atomic mass units (amu), which is slightly heavier than the most abundant isotope (12 amu) due to the presence of the less abundant isotope (13 amu). This concept is important in chemistry because the mass of atoms plays a crucial role in determining their chemical and physical properties. The knowledge of the average atomic mass of an element is important in a wide range of applications, including analytical chemistry, geochemistry, and nuclear physics.

Guys I really need to you answer this question for me pleaseeeee. Describe one situation in which forces are created.
Answers
The application of force in the direction of the motion of an object. The second scenario involves applying force to a moving item that is traveling in the opposite direction.
What is force ?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. A force has both a direction and a magnitude.
Force is used to describe a body's tendency to modify or change its state as a result of an external cause. When force is applied, the body can also alter its size, shape, and direction.
A push or pull that an object experiences as a result of interacting with another item is known as a force. Every time two items interact, a force is exerted on each of the objects. The force is no longer felt by the two objects when the interaction ends.
Thus, Force applied to an item in motion that originates in any direction constitutes the third situation where force is created.

have 154.3 L of gas held at 27 degrees Celsius and a pressure my instruments cannot measure. I change the pressure to 1.5 atm, and the temperature rises to 40.0 degrees Celsíus, while the volume decreases to 50.0 L. What was the original pressure?
Answers
Answer
P1 = 0.466 atm
Explanation
Given:
Initial volume (V1) = 154.3 L
Final volume (V2) = 50.0 L
Initial Temperature (T1) = 27 °C = 300 K
Final Temperature (T2) = 40.0 °C = 313 K
Initial pressure (P1) = ?
Final pressure (P2) = 1.5 atm
Required: Initial pressure (P1)
Solution
To solve this problem, we will use combined gas law:
\(\frac{P_1V_1}{T_1}\text{ = }\frac{P_2V_2}{T_2}\)Re-arrange:
P1 = (P2V2T1)/T2V1
P1 = (1.5 x 50.0 x 300)/(313 x 154.3)
P1 = 0.466 atm

What is the final temperature after 840 Joules is absorbed by 10.0g of water at 25.0
C?
Answers
The final temperature of the water is: T_final = 45.0°C
We can use the formula for the specific heat capacity of the water to solve this problem:
q = mcΔT
First, we can calculate the initial energy of the water:
q = mcΔT
q = (10.0 g) (4.184 J/g°C) (25.0°C)
q = 1,046 J
Next, we can calculate the final temperature after absorbing 840 J:
q = mcΔT
840 J = (10.0 g) (4.184 J/g°C) (ΔT)
ΔT = 20.0°C
Therefore, the final temperature of the water is:
T_final = T_initial + ΔT
T_final = 25.0°C + 20.0°C
T_final = 45.0°C

By the concept of calculating moles ,it can br concluded that the no. of atoms of phosphorus in 8.80mol of copper(II) phosphate is=1.06\(x10^{25}\)
A mole is defined as amount of substance containing as many as elementary entities that are there in atoms of exactly 12 g of carbon-12.Therefore we can say,1 mole of copper(II) phosphate, Cu3(PO4)2, contains three moles of copper(II) cations and two moles of phosphate anions.
Again 1mole of phosphate anions contains one mole of phosphorus and four moles of oxygen.Considering all these informations we can conclude that:1 mole of copper(II) phosphate contains 2 moles of Phosphorus
Accordingle the sample contains=(8.80\(x\)2) moles of Phosphorus
=(17.6\(x\)Avogadro's constant) atoms of Phosphorus

In 8.80 moles of copper(II) phosphate, there are approximately 1.06 x 10²⁵ atoms of phosphorus.
Explanation:The number of atoms of phosphorus in a given amount of a compound can be calculated using the concept of mole in chemistry. Copper(II) phosphate is Cu3(PO4)2, containing 2 moles of phosphorus (P) for every 1 mole of the compound. Avogadro's number (6.022 x 10²³) gives the number of atoms in one mole.
So, if there are 8.80 moles of copper(II) phosphate, there would be 2 × 8.80 moles of phosphorus. Multiplying this by Avogadro's number gives the total number of phosphorus atoms.
Therefore, the number of phosphorus atoms is 2 × 8.80 × 6.022 x 10²³ = 1.06 x 10²⁵ atoms of phosphorus.

CHALLENGE The circles below represent of the large circle, and multiply it by 30. That Earth and the moon. Measure the diameter would be the correct distance from Earth to the moon at this scale. Draw the two circles in the space provided. Use the correct distance you found.● = Earth ●=moon
Answers
To draw the two circles, we would need to draw a smaller circle with a diameter of 2,532.5 miles (representing the moon) and a larger circle with a diameter of 75,974.4 miles (representing the Earth) that is 30 times larger than the smaller circle.
What is the explanation for the above response?If we assume that the larger circle represents the Earth, then the diameter of the Earth would be 30 times the diameter of the smaller circle representing the moon. Let's say that the diameter of the smaller circle is x. Then the diameter of the larger circle (Earth) would be 30 times x or 30x.
To find the correct distance from Earth to the moon at this scale, we need to know the actual distance from Earth to the moon, which is approximately 238,855 miles or 384,400 kilometers. If we divide this distance by the scale factor of 30, we get:
238,855 miles / 30 = 7,961.8 miles
Therefore, the diameter of the smaller circle (moon) would be approximately 7,961.8 miles / π = 2,532.5 miles (rounded to one decimal place). And the diameter of the larger circle (Earth) would be 30 times that or 75,974.4 miles
So, to draw the two circles, we would need to draw a smaller circle with a diameter of 2,532.5 miles (representing the moon) and a larger circle with a diameter of 75,974.4 miles (representing the Earth) that is 30 times larger than the smaller circle.

Answers
Answer:
Close to the calculated endpoint of a titration - Partially open
At the beginning of a titration - Completely open
Filling the buret with titrant - Completely closed
Conditioning the buret with the titrant - Completely closed
Explanation:
'Titration' is depicted as the process under which the concentration of some substances in a solution is determined by adding measured amounts of some other substance until a rection is displayed to be complete.
As per the question, the stopcock would remain completely open when the process of titration starts. After the buret is successfully placed, the titrant is carefully put through the buret in the stopcock which is entirely closed. Thereafter, when the titrant and the buret are conditioned, the stopcock must remain closed for correct results. Then, when the process is near the estimated end-point and the solution begins to turn its color, the stopcock would be slightly open before the reading of the endpoint for adding the drops of titrant for final observation.
