Diazene, N2H2 (also Known As Diimine), Is Commonly Used As A Reagent For Organic Syntheses. Label Each

Answers

Answer 1

The first image shown at the left hand side is a pi bond. The other two images show sigma bonds.

In chemistry, a bond results from the overlap of atomic orbitals. This overlap may be end to end (sigma bond) or side by side (pi bond). Having said this, it is easier to decide whether the bonds in the image shown are sigma or bi bonds.

If we label the images; 1,2,3 from left to right, we can see that the overlap in image 1 is side by side. The electron density lies above and below the plane of the bond. This is a pi bond. In images 2 and 3, the overlap occurs in an end to end manner. This is a sigma bond.

What is the molarity of aqueous lithium bromide if 25.0 mL of LiBr reacts with 10.0 mL of 0.250 M Pb(NO 3) 2

Answers

The molarity of aqueous lithium bromide, LiBr solution is 0.2 M

We'll begin by calculating the number of mole of Pb(NO₃)₂ in the solution.

Volume = 10 mL = 10 / 1000 = 0.01 L Molarity of Pb(NO₃)₂ = 0.250 MMole of Pb(NO₃)₂ =?

Mole = Molarity x Volume

Mole of Pb(NO₃)₂ = 0.25 × 0.01

Mole of Pb(NO₃)₂ = 0.0025 mole

Next, we shall determine the mole of LiBr required to react with 0.0025 mole of Pb(NO₃)₂

Pb(NO₃)₂ + 2LiBr —> PbBr₂ + 2LiNO₃

From the balanced equation above,

1 mole of Pb(NO₃)₂ reacted with 2 mole of LiBr.

Therefore,

0.0025 mole of Pb(NO₃)₂ will react with = 2 × 0.0025 = 0.005 mole of LiBr

Finally, we shall determine the molarity of the LiBr solution

Mole = 0.005 mole Volume = 25 mL = 25 / 1000 = 0.025 L Molarity of LiBr =?

Molarity = mole / Volume

Molarity of LiBr = 0.005 / 0.025

Molarity of LiBr = 0.2 M

For an imaginary closed economy, T = $5,000; S = $11,000; C = $48,000; and the government is running a budget surplus of $1,000. Then

Answers

Based on the information given, the private savings will be $10000 and the gross domestic product is $63000.

From the information given, he following can be gotten:

T = $5,000S = $11,000C = $48,000Budget surplus = $1000

Since, S = Y - C - G

11000 = Y - 48000 - G

Y - G = 48000 + 11000

Y - G = 59000

Budget surplus = T - G = 1000

5000 - G = 1000

G = 5000 - 1000 = 4000

The GDP will be:

Y - G = 59000

Y - 4000 = 59000

Y = 59000 + 4000 = 63000

Private savings = Y - T - C

Private savings = 63000 - 5000 - 48000

Private savings = 10000

cheaper nickel (Ni) ring. Is this a good idea? Explain your answer. (3 points)

Answers

Answer:

No. While gold would not react with a silver nitrate solution, nickel would.

Explanation:

Refer to the metal reactivity series.

Reactivity: [tex]\text{Gold} < \text{Silver} < \text{Nickel}[/tex].

Gold is positioned after silver in the reactivity series, meaning that gold is typically less reactive than silver. Thus, gold would not react with a solution of silver ions to produce silver metal.

However, since nickel is positioned before silver in the reactivity series, it is expected that nickel would react with silver ions in this solution to produce silver metal.

Thus, if the silver nitrate solution comes into contact with the two rings, the nickel ring would likely react with the solution, the gold ring would not.

A Carnot engine takes 2000 j of heat from a reservoir at 500 k, does some work and discards some heat to a reservoir at 350k . how much work does it do, how much heat is discarded, and what is it's efficiency?​

Answers

Answer:

Explanation:

The Carnot engine is a theoretical or conceptual heat engine that has a higher efficiency than any practical or theoretical heat engine working between the same temperature range. The theoretical efficiency of a Carnot engine is considered as the highest efficiency and no practical heat engines can operate at that efficiency. A Carnot engine draws heat energy, performs useful work and the leftover energy is released from the working substance. According to the second law of thermodynamics, there must be a temperature gradient between the heat energy drawing point and release point of the heat engine.

Glucose is a type of simple sugar (carbohydrate) that does not further hydrolyze to give monosaccharides.

Ball and stick model: The atoms are portrayed as different colored balls connected to each other by "sticks." Fischer projection: The atoms on the sides of the plane are coming out of the plane, while the atoms at the ends are moving behind.Bond line notation: It is the most frequent representation method used; it lacks C and H bonds but instead depicts carbons through bends.

Answers

The volume of the sodium hydroxide solution needed for the reaction is 0.3 L

We'll begin by writing the balanced equation for the reaction.

H₂X + 2NaOH → 2H₂O + Na₂X

From the balanced equation above, the following data were obtained:

The mole ratio of the acid, H₂X (nA) = 1The mole ratio of base, NaOH (nB) = 2

From the question given above, the following data were obtained:

Molarity of base, NaOH (Mb) = 0.2 M. Volume of acid, H₂X (Va) = 0.3 L. Molarity of acid, H₂X (Ma) = 0.1 M. Volume of base, NaOH (Vb) =?

MaVa / MbVb = nA / nB

(0.1 × 0.3) / (0.2 × Vb) = 1/2

0.03 / (0.2 × Vb) = 1/2

Cross multiply

0.03 × 2 = 0.2 × Vb

0.06 = 0.2 × Vb

Divide both side by 0.2

Vb = 0.06 / 0.2

Vb = 0.3 L

Therefore, the volume of NaOH needed for the reaction is 0.3 L
