The general formula for a cyclic alkene is CnH2n, where n is the number of carbon atoms in the cyclic structure.
The double bond is typically placed between two carbon atoms, but may also involve one or more atoms of other elements such as nitrogen or oxygen.
The double bond is represented by a line connecting the two atoms. Cyclic alkenes can have any number of double bonds, depending on the size of the cyclic structure and the elements involved. Cyclic alkenes with more than one double bond can be expressed as CnH2n-2x, where x is the number of double bonds.

A pure substance is one that cannot change state or divide into other substances, except for a chemical reaction.
Classify these substances? In chemistry and related fields, a mixture refers to a substance that is composed of two or more substances. This is the opposite of a pure substance that has not been combined with others. In the case of the vegetable soup, this is a mixture because it integrates multiple substances such as water, salt, vegetables, etc.On the other hand, a mixture is classified as homogeneous if the elements are completely integrated, and the final substance is uniform or as heterogeneous if the mixture is not uniform. In the case of the soup, this can be classified as a heterogeneous mixture because in most cases you can identify the elements in it such as pieces of vegetables and therefore it is not a uniform or homogeneous mixture.N2, Nitrogen is known as the chemical element that is characterized by having atomic number 7 and that is symbolized by the letter N, in its molecular version, it is recognized as N2.To learn more about substance refer to;

Is Geh4 polar or nonpolar?
Is H2O polar or nonpolar? I believe its a polar molecule.
Is CO2 polar or nonpolar?
GeH4 is a non polar molecule.
H2O is a polar molecule.
CO2 is a nonpolar molecule.
The polarity of a molecule depends on the distribution of electrons within it. In a polar molecule, the electrons are distributed unevenly, causing an imbalance of charge and creating a partial positive and partial negative charge. In a nonpolar molecule, the electrons are distributed evenly, creating no imbalance of charge and no partial positive or negative charges.
The molecular geometry of GeH4 is tetrahedral with a symmetric charge distribution. Therefore this molecule is nonpolar.
H2O is a polar molecule because of its bent shape and the presence of polar bonds between the central O atom and the two H atoms. The H atoms are more electronegative than the central O atom, which causes the electrons to be pulled more towards the H atoms. This creates a partial positive charge on the O atom and a partial negative charge on the H atoms, making the molecule polar.
CO2 is a nonpolar molecule because the two C=O bonds are polar, but the molecule has a linear shape and the polarities of the two bonds cancel each other out, resulting in no net dipole moment and therefore the molecule is nonpolar.

this reaction is an example of conjugate addition of a nucleophile to an α,β-unsaturated carbonyl.
Yes, it is correct, this reaction is an example of conjugate addition of a nucleophile to an α,β-unsaturated carbonyl.
In this type of reaction, a nucleophile attacks the carbon atom in the carbonyl group that is adjacent to the double bond (the α-carbon), forming a new carbon-carbon bond and creating a tetrahedral intermediate. The intermediate then collapses, resulting in the formation of a new carbon-carbon bond and the addition of the nucleophile to the double bond. An α,β-unsaturated carbonyl is a compound that contains a carbonyl group (C=O) and a double bond (C=C) in which the carbonyl carbon (C=O) and the double-bonded carbon (C=C) are adjacent to each other. An example of an α,β-unsaturated carbonyl compound is an unsaturated aldehyde or unsaturated ketone.

The rate constant is 0.33 M-²s-¹.
What is rate law?One or more reagents and one or more product will always be present in a chemical reaction. The concentration of each of the reagents present may affect how quickly the reaction to create these products proceeds. The rate law describes this reliance. Each reactant concentration phrase in this law is given an exponent termed an order, which can have a value that is positive, negative, fractional, or zero. These ordering must be established through numerous experimental trials, unless the reaction is a simple one-step reaction. Finding the rate constant of the rate law follows the determination of these order values.
2a + 2b + c ⟶ d + 3e
For this reaction rate law can be written as,
rate = k(a)^x(b)^y(c)^z
Where x, y, z are reactant concentration orders,
To find the reaction orders we need to select a pair of trails which only one reactant varies,
For reactant a with an order of x we can select,
rate2/rate1 = ([a]2/[a]1)^x
9.6 × 10-⁵/6.0 × 10-⁶ = (0.096/0.024)^x
16 = 4^x
x = 2
Now for reactant b with order of y,
rate4/rate2 = ([b]4/[b]2)^y([a]4/[a]2)²
1.5 × 10-⁶/9.6 × 10-⁵ = (0.170/0.085)^y(0.012/0.096)²
1/64 = 2^y 1/64
y = 0
Now for reactant c with order of z,
rate3/rate1 = ([c]3/[c]1)^z ([b]3/[b]1)⁰
1.5 × 10-⁵/6.0 × 10-⁶ = (0.080/0.032)^z
2.5 = 2.5^z
z = 1
The reactant orders are x,y,z = 2,0,1.
we can use trail 1 to find rate constant,
rate = k[a]²[c]

Filtration is a separation method used to separate out pure substances in mixtures comprised of particles—some of which are large enough in size to be captured with a porous material. Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoa. Some water filters can filter out bacteria, the length of which are on the order of 1 micron. Other mixtures, like soil, have relatively large particle sizes, which can be filtered through something like a coffee filter.

Conduction is when the hotter object is touching the colder object and is heated by touch. An example is a hot burner and room temperature pan. If you put the pan on the burner, through touch, it will, eventually, become as hot as the burner.

The emission spectrum of the hydrogen atom shows that: c. Discrete emission lines at very specific wavelengths are observed, because only specific H atom energy levels are possible.
The emission spectrum of the hydrogen atom shows the specific wavelengths of light that are emitted when the electron in the hydrogen atom jumps from a higher energy level to a lower energy level. These wavelengths correspond to specific colors of light, and are unique to hydrogen.
The most well-known example is the Balmer series, which produces the visible lines in the hydrogen spectrum. This is used to identify the presence of hydrogen in stars and other astronomical objects.
