Which of the following statements about the Diels-Alder reaction are TRUE?
andreev551 [17]

Answer:

A.It is a reaction involving pi-electrons.

D.It is *not* a reaction favored by entropy considerations.

Explanation:

The Diels-Alder reaction is a [4+2]- cycloadition that involoves pi-electrons (4 from the diene and 2 from the dienophile).

The reaction is favored by the formation of new sigma bond, since they are more stable than pi-bonds. This reaction is not favored by entropy because there are 2 reactants and one product and the order increases.

The reaction happens in one step.

3. You measure a cube and determine that its sides are 0.65m. You place the cube on a mass scale and determine that this cube ha
amid [387]

The density of the cube in-

Kg/m³= 38.234 kg/m³

g/mL= 0.038234 g/mL

Explanation:

We know that volume of the cube equals m ³

Where “m” equals side of the cube

Given data-

Side of the cube=0.65m

mass of the cube= 10,500 gm

We know that 1000gm= 1 kg

Hence, 10,500 gm= 10.5 kg

Volume of the cube= (0.65)³

∴ Volume= 0.274625 m ³

We know that density = mass/volume

⇒Substituting the value of mass and volume, we get-

⇒Density= 10.5/0.274625= 38.234 kg/m³

We know that 1 kg/m³= 0.001 g/mL

Hence 38.234 kg/m³ would equal 0.038234 g/mL

Hence the density of the cube is 38.234 kg/m³ and 0.038234 g/mL

Why this chemical equation 3P4 + 10O2 = 4P2O5 + P4 is wrong?
ad-work [718]

Because it can be balanced in an infinite number of ways so it would need to be rewritten in a simpler form.
