Classify a substance composed of molecules each of which contains two iodine atoms as an element, a compound, or a mixture
(a) Element. (b) Compound. (c) Element. (d) Element. (e) Mixture. (f) Compound. (g) Element. (h) Mixture. Explanation: Hello, Matter could be widely classified as elements which are defined as single atoms of a particular element in the periodic table, compounds which are composed by two or more different bonded atoms (elements) in the same structure and mixtures which are composed by two or more atoms or substances that are not chemically bonded. In such a way the answers are: (a) Element: one copper atom. (b) Compound: two hydrogen atoms and one oxygen atom. (c) Element: one nitrogen atom. (d) Element: one sulfur atom. (e) Mixture: about 79% of nitrogen and 21% of oxygen. (f) Compound: constituted by carbon, hydrogen and oxygen. (g) Element: this is more specifically a molecule since two iodine atoms are contained. (h) Mixture: it is a mixture of many liquid aliphatic and aromatic hydrocarbons, ranging between C4 and C12 carbon atoms. Best regards.
A substance that is made up of molecules, each of which
contains two iodine atoms is called an element. A species of atoms having the atomic number and the same
number of protons in their atomic nuclei (i.e. the same atomic number, or Z).
is called a chemical element or simply element. 118 elements were already
identified, and the first 94 of them occur on Earth naturally, while the
remaining 24 are synthetic elements. Even with chemical means, elements cannot
be broken down into simpler substance. The most common element in the Earth’s
crust that is known to mankind is oxygen.
An element. Explanation: Hello, In this case, your talking about an element since it is composed by two atoms of the same element, here iodine, thus, if you were talking about a compound, it would be formed by two or more different elements. Best regards.
Explanation: An element is defined as a substance which contains same type of atoms. For example, a small block made up of only copper metal will contain only atoms of copper. A compound is defined as a substance in which atoms chemically combine together in a fixed ratio by mass. For example, HgO is a compound. A mixture is defined as a substance in which two or more components are physically combined but none of the components are chemically combined to each other. For example, a pan cake syrup is a mixture. Components of a mixture can be separated by physical means. Thus, we classify each of the given species as follows. iron – elementoxygen – elementmercury oxide – compoundpancake syrup – mixturecarbon dioxide – compounda substance composed of molecules each of which contains one hydrogen atom and one chlorine atom – compoundbaking soda – compoundbaking powder – compound
