List four methods that can be used to separate mixturea and give an example of each method​
Evgesh-ka [11]

Distillation, Filtration, evaporation, and Chromatography

The filtration process is generally used to separate a suspension mixture where small solid particles are suspended in liquid or air.

Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points..

Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates

Evaporation is a technique used to separate out homogenous mixtures where there is one or more dissolved solids. This method drives off the liquid components from the solid components

Which of these species is not an acidic oxide?
lesantik [10]

d. CO (carbon monoxide) is not an acidic oxide.

Acidic oxides are those oxides which either act as acceptors of the hydroxide ions (OH-) and function as a Lewis acid or they produce an acidic solution when added to water. Examples of acidic oxides are P4O10 (Phosphorus pentoxide), P4O6 (Tetraphosphorus hexaoxide), SO3 (Sulfur trioxide), SiO2 (Silicon dioxide) etc.

Neutral oxides do not show either of the basic or acidic properties. Due to this fact, they do not form salts when they react with acids or bases. Examples of neutral oxides include CO (carbon monoxide), NO (Nitric oxide), N2O (Nitrous oxide) etc.

Hence, option d is correct.
