2. Kelompok zat-zat di bawah ini yang merupakan unsur yaitu

raksa, hidrogen, dan udara

natrium, karbon, dan fosfor

air, besi, dan tembaga

alkohol, air, dan minyak

The correct answer is natrium, karbon, dan fosfor. These are elements because they cannot be broken down into simpler substances by chemical means. Mercury, hydrogen, and air are not elements because they are either compounds or mixtures. Water, iron, and copper are also not elements because they are compounds made up of different elements. Alcohol, water, and oil are also not elements because they are compounds or mixtures.

Explanation

The statement is true. A mixture in which the solvent and solute cannot be distinguished is called a compound.

5. Pasangan unsur dan senyawa berturut-turut yaitu

H2 dan He

H2 dan H2O

Ar dan N2

ZnO dan K2O

The correct answer is Ar dan N2 because Ar represents the element Argon and N2 represents the compound Nitrogen gas. Argon is a noble gas and Nitrogen gas is a diatomic molecule composed of two nitrogen atoms.

Explanation

The correct answer is Ar dan N2 because Ar represents the element Argon and N2 represents the compound Nitrogen gas. Argon is a noble gas and Nitrogen gas is a diatomic molecule composed of two nitrogen atoms.

6. Penamaan yang benar untuk NaF adalah _____

The correct answer is "Natrium fluorida" because NaF is the chemical formula for sodium fluoride. In chemical nomenclature, "natrium" is the Latin name for sodium, and "fluorida" indicates the presence of fluoride ions. Therefore, "Natrium fluorida" is the appropriate name for NaF.

8. Zat berikut ini yang semuanya senyawa yaitu

Natrium,krom,dan karbon

Seng,besi dan kapur

Alkohol,air dan api

Air,gula dan garam

The correct answer is "Alkohol, air dan api" and "Air, gula dan garam". These options consist of compounds because compounds are substances that are formed when two or more elements chemically combine. In the first option, alcohol is a compound made up of carbon, hydrogen, and oxygen atoms. Water is also a compound made up of hydrogen and oxygen atoms. Fire, although not a substance itself, is a result of a chemical reaction between a fuel and oxygen. In the second option, air is a mixture of different gases, but some of these gases, such as oxygen and nitrogen, are compounds. Sugar and salt are also compounds made up of different elements.
