Iron is magnetic and the other two not, which means a MAGNET could be used to ATTRACT the iron filings out of the mixture, LEAVING the salt and sand. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.

Unlike most organic compounds, dyes possess colour because they 1) absorb light in the visible spectrum (400–700 nm), 2) have at least ONE chromophore (colour-bearing group), 3) have a conjugated SYSTEM, i.e. a structure with alternating double and single bonds, and 4) exhibit resonance of electrons, which is a stabilizing force in organic compounds (Abrahart, 1977). When any one of these features is lacking from the MOLECULAR structure the colour is lost. In addition to chromophores, most dyes also contain groups known as auxochromes (colour helpers), examples of which are carboxylic acid, sulfonic acid, amino, and hydroxyl groups. While these are not responsible for colour, their presence can shift the colour of a colourant and they are most often used to influence dye solubility. Figure 1 shows the relationships between wavelength of visible and colour absorbed/observed. Other factors contributing to colour are illustrated inRegarding the REQUIREMENT of a chromophore generating colour in organic compounds, it is important to note that the chromophore must be part of a conjugated system. This is illustrated through the examples in Figure 5 where it can be seen that placement of an azo group between methyl groups produces a colourless compound, while a yellow-orange colour is obtained when the azo group is placed between aromatic rings. Similarly, the structures in Figure 3 demonstrate the importance of having an extended conjugated system. It is evident that doubling the length of the conjugated system in Vitamin A to give β -carotene causes a significant bathochromic shift, i.e. to a darker colour.In addition to influencing solubility, auxochromes are essential ring substituents in providing target colours. This is illustrated in Figure 6, where the following effects of substituents are shownAdding groups of increasing electron-donating ability to the azobenzene structure has a bathochromic effect (cf. OH vs NH2).Electron-donating (NH2) and electron-accepting (NO2) groups placed in conjugation provide a bathochromic effect. In this regard, nitro groups are especially beneficial, contributing to their prevalence in disperse dye structures.Increasing the number of electron-attracting groups conjugated with the electron-donor has a bathochromic effect.The electron-donating effects of an amino group are enhanced by adding alkyl groups to the N-atom.

Correct QUESTION :- Calculate the MASS of KOH required to make 250mL of 0.2 M solution.Answer:- 2.8g.Explanation :- Let the required mass of KOH be 'x' g. • Molar mass of Potassium (K) = 39g/mol. • Molar mass of Oxygen (O) = 16g/mol. • Molar mass of HYDROGEN (H) = 1g/mol. HENCE, molar mass of KOH :- = 39+17+1. = 56g/mol.

Chemical kinetics, also known as REACTION kinetics, is the branch of physical chemistry that is concerned with UNDERSTANDING the rates of chemical reactions. It is to be contrasted with thermodynamics, which deals with the direction in which a process OCCURS but in itself TELLS nothing about its rate.

Temperatures are rising world-wide due to GREENHOUSE gases trapping more heat in the atmosphere. DROUGHTS are becoming longer and more extreme around the world. TROPICAL storms becoming more severe due to warmer OCEAN water temperatures.

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the PRODUCTS. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent ATOMS of the reactants to create different substances as products.The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these CATEGORIES. Some reactions will fit into more than one category.Explanation:Please MARK Me As Brainliest Thank Me If The Answer Is Correct Thank you.
