hii answer isExplanation: Heat2KClO 3 Heat 2KCl+3O 2 The mole ratio for the reaction is 2:2:1 meaning, two MOLES of KClO 3 yields 2 moles of KCl and 3 moles of O 2 CALCULATE the moles of oxygen from the 6.72 dm 3 given1 dm 3 =1 liter 6.72 dm 3 =6.72 liters of oxygenUsing the ideal gas law, which states that 1 mole of an ideal gas occupies 22.4 liters by volume we can calculate the moles of oxygen as follows:If 22.4 liters = 1 moleThen 6.72 liters = 1 × 6.72/ 22.4 = 0.3 molesFrom the equation above we FOUND the mole ratio for the equation to be 2:2:1That means, for 0.3 moles of oxygen to be liberated, we will need 0.3 × 2 = 0.6 moles of KClO 3 USE the 0.6 moles of KClO₃ to find the mass requiredMoles = mass / molar mass Then,mass = molar mass × molesmolar mass of potassium chlorate is 122.5 g/mol (GIVEN) and moles is 0.6(calculated)Therefore mass of KClO 3 required = 122.5 g/mol x 0.6 moles = 73.5 gTherefore you need 73.5 g of potassium chlorate to liberate 6.72 dm 3 of oxygen.

The names of the METALS P, Q , R, S which are OBTAINED by the reduction of their oxides with carbon are Zinc, Tin, LEAD, Iron respectively. We reach to this conclusion because: On metal Iron a thin coating of Zinc is formed by the process called galvanization. This coating prevents the iron from GETTING rusted as  zinc has high reactivity and hence protection is given against corrosion. By electroplating tiffin boxes which are made of Iron with Tin, protection is conferred to iron against outside corrosion. In the making of CAR batteries, lead is being used. An alloy solder is formed by combining tin and lead.

Electrolytic REFINING: It is the process of refining of metal in which IMPURE metal is made the anode and a THIN strip of pure metal is made the cathode.

In metallurgy, refining consists of PURIFYING an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical CHANGE to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and hydrometallurgical techniques.Explanation:In order to isolate noble-metalliferous materials, pyrolysis and/or hydrolysis PROCEDURES are used. In pyrolysis, the noble-metalliferous products are released from the other materials by solidifying in a melt to become cinder and then poured off or oxidized. In hydrolysis, the noble-metalliferous products are dissolved either in aqua regia (consisting of hydrochloric acid and nitric acid) or in hydrochloric acid and chlorine gas in solution. Subsequently, certain metals can be precipitated or reduced directly with a salt, gas, ORGANIC, and/or nitro hydrate connection. Afterwards, they go through cleaning stages or are recrystallized. The precious metals are separated from the metal salt by CALCINATION. The noble-metalliferous materials are hydrolyzed first and thermally prepared (pyrolysed) thereafter. The processes are better yielding when using catalysts that may sometimes contain precious metals themselves. When using catalysts, the recycling product is removed in each case and driven several times through the cycle.Thanks for the question. Hope it helps you.

The method used to extract a metal from its ore depends upon the stability of its compound in the ore, which in turn depends upon the reactivity of the metal. ... Reduction with carbon is often used to extract these METALS and requires less energy to reduce them to extract the metal.Explanation:Reactivity series depicts the reactivities of metals in decreasing order. It is very helpful in the extraction of metals. The extraction of metals depends on their reactivities.For extraction purpose, metals in the reactivity series are ordered under three sections:1. Highly reactive metals2. Moderately reactive METALS3. Low reactive metalsDepending on the reactivities, different methods are applied for extracting metals from their ores.Sodium, POTASSIUM, calcium, magnesium and aluminium are highly reactive metals and placed at the top of the reactivity series. These metals are extracted by electrolytic reduction of their molten CHLORIDES or oxides because these metals are not reduced by other reducing agents like coke, carbon monoxide etc.Moderately reactive metals like zinc, iron, lead and copper are placed at the middle of the reactivity series. They are reduced by carbon because carbon is more reactive than these metals and can reduce their metal oxides to metal easily. However, manganese is more reactive than zinc (above zinc in reactivity series); therefore, it cannot be reduced by carbon. It is reduced by a more reactive reducing agent aluminium. Aluminium reduces manganese dioxide to manganese on heating.Low reactive metals like copper and mercury are placed at the bottom of the reactivity series and are extracted by heating their ores ALONE. We should note that ores of copper can be extracted by both − reduction with carbon (copper (I) oxide) and heating alone (copper (I) sulphide). Thanks for the question. Hope it helps you.

Pyrolusite is made up primarily of the compound manganese dioxide (MnO 2 ).(c)Roasting: When zinc sulphide (zinc blende ORE) is strongly heated in air (roasted), it forms zinc oxide and SULPHUR dioxide.

The SUBSTANCE LIKE solid air fresheners which are used to enhance fragrance of a particular place when applied, is a covalent compound.Solid air fresheners are volatile  in nature and they have low boiling points and melting points just like the covalent compounds.Air fresheners are the substance which enhances good SMELL in the air, when applied. They are of two types, liquid and solid. They CONTAINS CHEMICALS like  essential oils which are plant derived product and gives a good fragrance. The fragrance is fixed in wax in case of solid air fresheners.
