Concept explainers
Interpretation:
Formation of Magnesium oxide by the reaction between magnesium and explosive oxygen, wrong statement for this reaction is to be determined.
Concept introduction:
When the metal reacts with the oxygen, they form metal oxides, which are found in powdery form. Magnesium reacts with explosive oxygen, an exothermic reaction. In an exothermic reaction, the reactants are highly reactive and formed a product with energy loss.

Answer to Problem 9STP
Correct Answer: The correct option is (d).
Explanation of Solution
Reason for correct option: In a
Hence, is a correct option.
Reasons for incorrect options:
Option (a), mass of magnesium and the mass of oxygen is equal to the mass of magnesium oxide, by the law of conservation. Hence, this is an incorrect option.
Option (c) There is the formation of a new product as an oxide in a chemical reaction. Hence, this is an incorrect option.
Option (d) The formed product is an example of metal oxide which is categorized as a compound, the compound is formed with a combination of two or more different elements. Hence, this is an incorrect option.

NBS, peroxide, Aarrow_forwardIn addition to the separation techniques used in this lab (magnetism, evaporation, and filtering), there are other commonly used separation techniques. Some of these techniques are:Distillation – this process is used to separate components that have significantly different boiling points. The solution is heated and the lower boiling point substance is vaporized first. The vapor can be collected and condensed and the component recovered as a pure liquid. If the temperature of the mixture is then raised, the next higher boiling component will come off and be collected. Eventually only non-volatile components will be left in the original solution.Centrifugation – a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.Sieving – this is…arrow_forwardBriefly describe a eutectic system.arrow_forward
