For the second reaction, draw the structure of the intermediate's resonance contributor that leads to the formation of 3-ethoxy-1-pentene.
Answers
Answer:
The first case is an SN2 reaction while the second case is an SN1 reaction
Explanation:
In the first case, what we have is an SN2 bimolecular reaction. It should be recalled that sodium ethoxide is a strong nucleophile. Strong nucleophiles lead to SN2 substitution in secondary alkyl halides where SN1 or SN2 mechanisms are probable. The observed mechanism now depends on the actual nucleophile used in the reaction. Since a strong nucleophile is used, 3-ethoxy-1-pentene is obtained as shown in the image attached to this answer.
In the second case, a weaker nucleophile, ethanol is used. The use of a weak nucleophile leads to an SN1 mechanism. The 3-Chloro-1-pentene forms a secondary carbocation as shown in the image attached. This secondary carbocation can re-arrange itself to give the two products; 3-ethoxy-1-pentene and 1-ethoxy-2-pentene as shown in the reaction mechanism in the image attached. The structure of the contributor leading to the formation of 3-ethoxy-1-pentene is clearly shown in the image attached.

Answers
Answer:
42.1 g of silver chloride (AgCl).
Explanation:
What is given?
Mass of silver nitrate (AgNO3) = 50.0 g.
Molar mass of silver nitrate (AgNO3) = 170 g/mol. (you can calculate this using the periodic table)
Molar mass of silver chloride (AgCl) = 143.4 g/mol.
Step-by-step solution:
First, let's balance the chemical equation by trial and error method:
\(AgNO_3+BaCl_2\rightarrow AgCl+Ba(NO_3)_2.\)You can see that we have Cl and NO3 unbalanced, so if we put '2' moles beside AgCl, chlorine (Cl) will be balanced for both sides, but Ag would be unbalanced and NO3 too, so if we put '2' moles beside AgNO3, we will obtain the balanced equation:
\(2AgNO_3+BaCl_2\operatorname{\rightarrow}2AgCl+Ba(NO_3)_2\)Now, let's do the stoichiometry of part a.
Let's convert 50.0 g of AgNO3 to moles using its given molar mass:
\(50.0\text{ g AgNO}_3\cdot\frac{1\text{ mol AgNO}_3}{170\text{ g AgNO}_3}=0.294\text{ moles AgNO}_3.\)And now, let's see how many moles of AgCl are being produced by 0.294 moles of AgNO3. You can see in the chemical equation that 2 moles of AgNO3 reacted, produces 2 moles of AgCl, so the molar ratio is 2:2, more simply is 1:1. This means that if we're using 0.294 moles of AgNO3, we will obtain 0.294 moles of AgCl.
Based on this logic, the final step is to find the mass of AgCl in grams, using its molar mass, like this:
\(0.294\text{ moles AgCl}\cdot\frac{143.4\text{ g AgCl}}{1\text{ mol AgCl}}=42.1\text{ g AgCl.}\)The answer is we will obtain 42.1 g of silver chloride (AgCl).
Consider mixing a liquid with a vapor pressure of 100 torr with an equimolar amount of a liquid with a vapor pressure of 200 torr. The resulting solution would be predicted to have a vapor pressure of 150 torr if it behaved ideally. If, however, the interactions between the different components are not similar we can see positive or negative deviations from the calculated vapor pressure. An actual vapor pressure greater than that predicted by Raoult's law is said to be a positive deviation and an actual vapor pressure lower than that predicted by Raoult's law is a negative deviation.

Part B

Answers
A homogenous mixture varies from a heterogenous mixture in that a homogenous mixture has properties that do not vary in the mixture. The correct answer is A.
A homogeneous mixture is a mixture in which the properties and composition are uniform throughout the mixture. This means that if you took a sample from any part of the mixture, you would find the same properties and composition in that sample as you would find in the entire mixture.
In contrast, a heterogeneous mixture is a mixture in which the properties and composition vary throughout the mixture. For example, a salad is a heterogeneous mixture because you can see different ingredients such as lettuce, tomatoes, and croutons, each with different properties and composition.
So, in a homogeneous mixture, the properties do not vary, while in a heterogeneous mixture, the properties vary throughout the mixture.

To find the order of a reaction with respect to one reactant, you will monitor the as the of . is changed.
Answers
The order of reaction is defined as the power to which the concentration of the reactants are raised in the rate equation of the reaction.
The order of reaction can be used to determine how a particular reactant affects the reaction. In order to find the order of a reaction with respect to a particular reactant, the concentration of the reactant is changed while keeping the concentration of other reactants constant. The rate of reaction is then measured and compared with the rate of reaction when the concentration of the reactant is not changed.The order of reaction with respect to a reactant can be determined using the following method:First, select a reactant whose order needs to be determined and change its concentration while keeping the concentration of other reactants constant. For example, if we want to find the order of reaction with respect to reactant A, we will change the concentration of A and keep the concentration of reactant B constant.Second, measure the rate of reaction at different concentrations of the reactant A. The rate of reaction can be measured by any suitable method such as change in color, pH, or by measuring the amount of product formed with time. A graph is plotted with rate of reaction on the y-axis and concentration of reactant A on the x-axis. The graph should be a straight line.Third, if the graph is a straight line passing through the origin, the order of reaction with respect to reactant A is one. If the graph is a straight line but does not pass through the origin, the order of reaction with respect to reactant A is two. If the graph is not a straight line, the order of reaction with respect to reactant A is either zero or fractional.For such more question on concentration

Redox reactionA redox reaction is one in which there is loss or gain of electrons. The equation of the reaction is 5Fe2+ + MnO4- + 8H+ - - > 5Fe2+ + Mn2+ +4H2O
Number of moles of permanganate = 0.0200 mol. dm3 * 18.10cm3/1000 L
= 0.000362 moles
If 5 moles of iron II reacted with 1 mole of permanganate
x moles of iron II reacts with 0.000362 moles of permanganate
x = 5 moles * 0.000362 moles/ 1 mole
= 0.00181 moles of iron II
Recall that;
Number of moles = mass/molar mass
Molar mass of iron II = 56 g/mol
0.00181 moles = x/56 g/mol
x = 0.00181 moles * 56 g/mol = 0.1 g
If 1 mole of the complex contains 1 mole of iron then;

As H₃PO₄ is catalyst and remains unchanged so we can also write as,
C₄H₁₀O → C₄H₈ + H₂O
c) Rule:
When more than one alkene products are possible then the one thermodynamically stable is favored. Thermodynamically more substituted alkenes are stable. Furthermore, trans alkenes are more stable than cis alkenes. Hence, in our case the major product is trans alkene followed by cis. The minor alkene is the 1-butene as it is less substituted.
d) C is not Geometrical Isomer:
For any alkene to demonstrate geometrical isomerism it is important that there must be two different geminal substituents attached to both carbon atoms. In 1-butene one carbon has same geminal substituents (i.e H atoms). Hence, it can not give geometrical isomers.

It certainly is easy to count bananas or to count elephants (as long as you stay out of their way). However, you would be counting grains of sugar from your sugar canister for a long, long time. Atoms and molecules are extremely small – far, far smaller than grains of sugar. Counting atoms or molecules is not only unwise, it is absolutely impossible. One drop of water contains about 10 22 molecules of water. If you counted 10 molecules every second for 50 years without stopping you would have counted only 1.6 × 10 10 molecules. Put another way, at that counting rate, it would take you over 30 trillion years to count the water molecules in one tiny drop.

In a sack of marbles there are red marbles each weighing 11.50g and green marbles which each weighing 12.70g. There are 10,051 red marbles and 24,351 green marbles. Determine the mass of the average marble in the sack. (Explain why the answer is not equal to (11.50 + 12.70) / 2 = 12.10g .
Answers
The mass of the average marble in the sack is 12.35 g.
Total number of marbles in the bag = number of red marbles + number of green marbles
Mass of each green marble = 12.70g
Mass of each red marble = 11.50g
Total mass of green marbles = 24,351(12.70g) = 309257.70 g
Total mass of red marbles = 10,051(11.50g) = 115586.50 g
Total mass of marbles in the sack = 309257.70 g + 115586.5 g = 424844.22 g
Total number of marbles in the sack = 24,351 + 10,051 = 34402 marbles
Therefore;
Mass of the average marble in the sack = 424844.22 g/34402 marbles
= 12.35 g
Hence, the mass of the average marble in the sack is 12.35 g
