wrought iron EXPLANATION:The PUREST form of iron is wrought iron. It CONTAINS 0.12 to 0.25% CARBON and it is the purest form of iron.

Reactions occurs in extraction of silver - AG2S + 4NaCN→ 2Na[Ag(CN)2] + NA2S (reversible reaction) 4Na2S + 5O2 + H2O→ 2Na2SO4 + 4NaOH + 2S and 2Na[Ag(CN)2] ..

❤ ANSWER flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal IONS, based on each element's characteristic emission spectrum. Samples are usually HELD on a platinum WIRE cleaned repeatedly with hydrochloric acid to remove TRACES of previous analytes. The compound is usually made into a paste with concentrated hydrochloric acid, as metal halides, being VOLATILE, give better results.Hope it helps uh !!

ve ANSWERS you QUESTION have any other QUERIES ASK me

The USE will depend on the metal it is bonded to. it's because C03 can't itself exist and the CARBONATE is CO3 with a negative charge... And so it can't be called OXYGEN TRIOXIDE....

tion:What Happens When You Mix Baking Soda With Vinegar to Inflate a Balloon?Updated April 25, 2017By Susan DavisBalloons, baking soda and vinegar lead to fun-filled, science-related experiments for any AGE. These materials are common in science classes from elementary to college. The chemical reaction caused by mixing baking soda and vinegar can cause balloons to race, homemade volcanoes to erupt and bubbles GALORE. Balloons are often used in baking soda and vinegar experiments because you can see the result of the chemical reaction.The Chemical ReactionBaking soda has the chemical name sodium bicarbonate. Vinegar is a combination of water and 5 percent acetic acid. SINCE both materials contain chemicals, when the two combine there is a chemical reaction. When vinegar and baking soda are mixed, a new chemical called carbonic acid is made. This carbonic acid immediately decomposes into carbon dioxide gas. When you mix the vinegar and baking soda, it's the carbon dioxide gas that makes the bubbles.Inflating a BalloonPut 1 teaspoon of baking soda in a medium-sized balloon. Empty a 1-liter water bottle and put 4 tablespoons of vinegar into the empty bottle. Place the balloon over the mouth of the water bottle. Turn the water bottle so that the vinegar pours into the balloon. Turn the bottle right side up and watch the balloon inflate. The balloon inflates because the carbon dioxide gas that is formed fills up the balloon. Try varying the AMOUNTS of baking soda and vinegar you use and see what happens.Interesting InformationThe chemical reaction that occurs to make the balloon inflate also happens when baking soda is used in cake and bread MIXES that don't contain yeast. There is a chemical reaction when the baking soda combines with the heat of the oven, making the cake or bread rise. Nahcolite is naturally forming sodium bicarbonate. It is found 2,000 feet under ground. Most baking soda that is bought from the store is artificially made.

14.44 * 10^23 electrons are present in 5.1 g NH3Explanation:17 is the molar mass of NH35.1 /17 gives the NUMBER of MOLES of NH3 in 5.1 grams of it. MULTIPLYING by 8 because in 1 mol NH3 there are 8 electrons. (Refer Lewis dot structure of NH3). Hence in 5.1 g 6.02 * 10^23 times electrons would be present.

In the EXTRACTION of chlorine by electrolysis of brine _oxidation of Cl– ion to chlorine gas occurs_.Explanation:2Cl– (AQ) + 2H2O(l) → 2OH– (aq) + H2(g) + Cl2(g)

(d) GalenaExplanation:Froth ­flotation METHOD is used for the concentration of sulphide ORES. The method is based on the PREFERENTIAL wetting properties with the frothing agent and water. In the given options, GALENA (PbS) is the only sulphide ore.

(c)Explanation:C(s) + O2 (g) → CO2 (g): Entropy of SOLIDS is NEGLIGIBLE. So here one molecule of gas is resulting in one molecule of gas. Hence there is almost no net entropy. So there will be no slope, it is completely horizontal. C(s) +  1/2O2(g) → 2CO(g): Here one mole of gas is giving you TWO moles of gas as PRODUCTS. So here the entropy will be positive. And as a RESULT, this curve will go downwards. Hence, the correct option is C.

bnormal MOLAR mass = 31.80 gm / moleTo Find:The degree of dissociation of sodium chloride (NaCl).Calculation:- Vant HOFF factor (i) is given as:Vant Hoff factor = (NORMAL molar mass) / (Abnormal molar mass)⇒ i = 58.5 / 31.80⇒ i = 1.84- For NaCl, n = 2- For dissociation, we have:Degree of dissociation = (i - 1) / (n - 1)⇒ α = (1.84 - 1) / (2 - 1)⇒ α = 0.84- Hence, the degree of dissociation of Sodium Chloride (NaCl) is 0.84.

Negative chargeExplanation:When silver nitrate solution is ADDED to KI solution, the precipitated AGI adsorbs iodide ions from the DISPERSION medium and negatively charged colloidal solution results. SINCE KI is in EXCESS, iodide ions (I-) will be adsorbed on the surface of AgI particles thereby giving them a negative charge.

(c) GalenaExplanation:GALENA (ZnS) is a sulphide ore. Galena is best concentrated by froth flotation method. The froth flotation process is USED to concentrate sulphide ores, BASED on preferential wetting properties with frosting AGENT and water.
