Hydration is the reaction with water.

The given options are "ბრტყელი" (complex), "ტეტრაედრული" (tetrahedral), "წრფივი" (linear), and "სამკუთხა" (triangular). Out of these options, "ტეტრაედრული" (tetrahedral) is the correct answer.

The two compounds shown in the image are homologues. Homologues are a series of compounds that have the same functional group and similar chemical properties, but differ by a repeating unit of CH2. In this case, the first compound has three carbon atoms, while the second compound has five carbon atoms. They both belong to the same homologous series of alkanes, differing by a CH2 unit.

The given answer suggests that both statement "როგორც ა" (as A) and statement "როგორც ბ" (as B) are correct. This means that both reactions Al4C3 + H2O → СН3СООNa + NaOH and Al4C3 + H2O → СН3СООNa + NaOH are possible in the laboratory.

The given question is asking for the molar mass of methane. The molar mass of methane is calculated by adding up the atomic masses of its constituent elements. The molecular formula of methane is CH4, which consists of one carbon atom with a molar mass of 12 g/mol and four hydrogen atoms with a molar mass of 1 g/mol each. Adding these up, we get a molar mass of 16 g/mol for methane. Therefore, the correct answer is 16 g/mol.

The correct answer is CH4 because it is the only option that does not contain any double or triple bonds between carbon atoms. The molecule CH4, also known as methane, consists of a single carbon atom bonded to four hydrogen atoms. In contrast, C8H10, C2H4, and C4H6 all contain multiple bonds between carbon atoms, which are indicated by the numbers in their chemical formulas.

Ethylene (ეთილის სპირტი) is formed through the process of hydration of ethylene. When ethylene (CH2=CH2) reacts with water (H2O), it undergoes hydration and forms ethylene glycol (ეთილენი). Therefore, the correct answer is ethylene glycol.

The given answer suggests that both statement "როგორც ა" and "როგორც ბ" are correct. This means that both reactions Al4C3 + H2O → СН3СООNa + NaOH are possible in the laboratory.

The correct answer is C4H10, which is the molecular formula for butane. Butane is an alkane with four carbon atoms and ten hydrogen atoms. It is a colorless gas at room temperature and is commonly used as a fuel for lighters and camping stoves.

The correct formula for the substance depicted in the image is C20H42.

The explanation for the given correct answer is that both statements 1 and 2 are true. The first statement states that the substance can be obtained with the use of potassium permanganate (KMnO4) as an oxidizing agent. The second statement states that the substance can be used as an antiseptic. Therefore, both statements are true and the answer is that both the first and second statements are true.

Hydration is the chemical reaction that is not represented in the given image for the substances mentioned.

The given answer, "გეომეტრიული იზმოერია" (geometric isomerism), is a possible explanation for the statement "სურათზე მოცემულ ნივთიერებას არ ახასიათებს" (The substance shown in the picture does not exhibit). Geometric isomerism refers to a type of stereoisomerism where molecules have the same molecular formula and connectivity but differ in the arrangement of their atoms in space. In this case, the substance in the picture is not exhibiting geometric isomerism, meaning it does not have different spatial arrangements.

The answer is correct because the first two statements state that "A and B are izomeri" and "B and C are homologues". The last statement states that "A and B are the same, C and D are the same substances". Therefore, it can be concluded that A and B are the same substances, and C and D are also the same substances.

In the given question, the options are different types of compounds. The correct answer is "ბენზოლი," which is the Georgian word for "benzene." Benzene is a colorless liquid hydrocarbon compound that is widely used in the chemical industry. It is often produced through the process of dehydrogenation of hexane, which is the conversion of hexane into benzene by removing hydrogen atoms. Therefore, benzene can be obtained through the dehydrocyclization of hexane.

The correct answer is "ერთი და იგივე ნივთიერება" because the objects in the picture are identical, meaning they are the same in terms of their shape, size, and color. The other options, such as "იზომერები" (magnifying glasses), "ჰომოლოგები" (homologues), and "იზოტოპები" (isotopes), do not accurately describe the objects in the picture.

The correct answer is "გ".

The given answer "აცეტილენი" is the correct answer because it is the only option that makes sense grammatically. The phrase "x ნივთიერებაა" translates to "x is an object" in English. Out of the given options, only "აცეტილენი" can be used as an adjective to describe an object. Therefore, it is the most suitable answer.
