Mendeleev's periodic table became widely accepted because it correctly predicted the properties of elements that had not yet been discovered.
Answer:
Explanation:
oxide or ferric oxide is the inorganic compound with the formula Fe₂O₃. It is one of the three main oxides of iron, the other two being iron(II) oxide, which is rare; and iron(II,III) oxide, which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe₂O₃ is the main source of iron for the steel industry. Fe₂O₃ is readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as Hydrous ferric oxide.
Answer:
The correct answer is Option
B. A homogeneous mixture
Explanation: Mixture is solution which is made of two or more than two substances which are combined only physically not chemically. There are two types of mixture i. e. Homogeneous mixture and heterogeneous mixture. Homogeneous mixture is a mixture in which the substances which are combined are uniform in appearance and heterogeneous mixture is a mixture in which substances are suspended in the solution and easily differentiated.

Answer:
2D structure is based on skeletal formula and
3D structure is based on ball and rod model
Explanation:
Please find the attached image of 2 D and 3 D structure of cis-4-nonene
The 2D structure of Cis-4 nonene resembles the shape of skeletal formula. Almost every organic molecule has notation of skeletal formula. Each carbon atom is connected to sufficient number of hydrogen atom so that the valence of each carbon atom is satisfied.
The carbon atom is located at the corner while the hydrogen atom are not indicated.
The three dimensional structure of Cis-4 nonene is based on stick and ball model where ball represents the various types of atoms and the rod length represents the bond. White ball represents the hydrogen atom and grey ball represents the carbon atoms.
