In compounds the word stress usually occurs on the first element whereas in noun phrases the second element is generally stressed if there is only one stress. (2) Semantic features. Compounds are different from free phrases in semantic unity. Every compound should express a single idea just as...
Alloys typically retain the physical properties of metals, such as electrical and thermal conductivity and ductility. In contrast, compounds can exhibit a wide range of physical properties that are often drastically different from their component elements. 14 While alloys are generally used in applicatio...
Ketone bodies are usually formed from the conversion of acetyl coenzyme A. Acetyl coenzyme A is a mitochondrial product produced due to the oxidation of fatty acids.Answer and Explanation: However, acetyl CoA can also be formed from the catabolism of fatty acids, which is ATP dependent and ...
Thus, two or more elements combine to form compounds.Answer and Explanation: Compounds are substances formed by combining two or more elements that always combine in a fixed ratio. Hence, compounds are composed of different......
very big if they are made of many chains of elements. Millions of compounds have been discovered, but this is estimated to be less than one percent of all compounds that are possible. Scientific estimates suggest that there could be as many as 10⁶⁰different possible compounds in ...
A mixture, however, is a combination of two or more substances that are not chemically bonded together and can be separated by physical means. Compounds have properties distinct from their component elements, while mixtures retain the properties of their individual substances. 6 In a compound, the...
(a) Hydrocarbons are the organic compounds containing only carbon and hydrogen atoms as their constituents. These may be alkanes, alkenes and akynes. (b) Saturated hydrocarbons or alkanes contains either C-C and C-H bonds in their molecules. These are
Why are compounds of transition metals, generally coloured ? View Solution Assing the reason for the following : (i) Transition metals generally form coloured compounds. (ii) Manganese exhibits highest oxidation state of +7 among the 3d series of transition elements. ...
Covalent compounds are formed when electrons are shared between the atoms and due to this sharing of electrons, they exhibit unique physical properties as compared to ionic compounds.Answer and Explanation: Some of the main properties of covalent compounds are : 1. Covalent compounds have a very...
