ANSWER - निष्क्रिय गैस से क्रिया करने वाला हैलोजन है - (द)F

अक्रिय गैसें असाध्य गैसें हैं। हलोजन जो अक्रिय गैस के साथ प्रतिक्रिया कर सकता है वह फ्लोरीन है। गैस की उच्च विद्युतीय प्रकृति के कारण यह संभव है।

क्सीनन और रेडॉन अक्रिय गैसों के उदाहरण हैं जो फ्लोरीन के साथ प्रतिक्रिया करने के लिए पाए जाते हैं। प्रतिक्रिया पर गठित यौगिक हैं XEF2, RnF2 आदि।

Answer & Explanation:

Yes, Hydrogen is prepared by Bosch process.

i. At first, heated coke is taken and it is MIXED with water at 3000°C in a specially built CHAMBER to form water gas.

C + H₂O --> [CO+H₂]

                  (water gas)

II. Then, we would be using some more water to the water gas using the CATALYST Fe₃O₄ in a specific pressure of 200-900mm at 450°C.

[CO+H₂O] + H₂O --> CO₂ + H₂

(water gas)

iii. Then, for separating CO₂ and CO, we would be doing the following:

• For separating CO₂, mix the products in a KOH (Potassium Oxide) solution.

• For separating some remaining CO, mix the products in Ammoniacal Cuprous (II) Chloride.

That's it, Hydrogen will be SEPARATED and it'll be extracted.

can U SHARE a PICTURE of that QUESTION

Explanation:

because the unknown salt will have sodium in it, so WHN NaOH ADDED to it common ion effect comes into effect and it shifts the reaction in backwards direction that is precipitation.

ASSUME given salt is CH3COONa

CH3COONa <=>CH3COO~ + Na+

NaOH ---> OH~ + Na+

in the above you can see the sodium ion concentration is INCREASED i.e it DISTURBED the equilibrium,

so according to Le chateleirs PRINCIPLE the reaction shift in backwards direction.

Here is your answer

In physics, a free surface is the surface of a FLUID that is subject to zero parallel SHEAR stress, such as the interface between two homogeneous fluids, for example liquid water and the air in the Earth's atmosphere. Unlike liquids, gases cannot form a free surface on their own.

Since solid consist of infinite NUMBER of atom and layers in particular arrangement therefore it contain infinite number of free surface. Liquid contain only one free surface because force of attraction is less between the atom which do not allow it have more than one free surface.

Answer:

Relative Atomic Mass of GOLD = 197

Meaning 197 g of Gold CONTAINS 6.02 x 10∧23 atoms of Gold (Avogadro's No.)

Mass of gold in the sample = 90% x 1 g = 0.9 g

If 197 g ≡ 6.02 x 10∧23 atoms

∴ 0.9 g ≡ (0.9 x 6.02 x 10∧23) ÷ 197

            ≡ 2.75 x 10∧21 atoms

Answer:As a first remark, you cannot have the same chemical species (here, H2O) among the reactants and among the products as well. So, you have to cancel it, either from the reactants or the products. If you remove it from reactants, only CO2 would be left as reactant, while the products include hydrogen-containing species glucose (C6H12O6). Since one basic law of chemistry is the impossibility of element transmutation (lead cannot be converted into gold!), some hydrogen containing species (namely, H2O) has to be present among the reactants; therefore, H2O has to be excluded from the products.

So, a more correct, still UNBALANCED, equation is : CO2 + H2O = C6H12O6 + O2 .

A practical, not SCIENTIFIC, way to balance relies on the fact that chemical reactions request the conservation of atoms, element by element. Remark that all the carbon atoms in the products are in the glucose (six carbon atom per glucose molecule), while all the carbon atoms in the reactants are in carbon DIOXIDE (one atom per molecule). So, tentatively, to balance the number of carbon atoms between reactants and products, write 6 as stoichiometric coefficient of CO2, and, implicitly, 1 as stoichiometric coefficient of C6H12O6. You get, as partial result,

6 CO2 + ? H2O = 1 C6H12O6 + ? O2 .

Now remark that all the hydrogen atoms in the products are in glucose (twelve H atoms per molecule), while in the reactants all of them are in water (two H atoms per molecule). So you need 6 water molecule to supply all the hydrogen atoms needed for one glucose molecule. Therefore, write a stochiometric coefficient 6 for water, and you get

6 CO2 + 6 H2O = 1 C6H12O6 + ? O2 .

At this point, remark that you have 18 oxygen atoms in the reactant molecules as a whole, while, among the products, the glucose molecule CONTAINS only 6 such atoms. Evidently, by the conservation of atoms of each element, the other 12 oxygen atoms have to be assigned to the oxygen molecule; since it is diatomic, six O2 molecules will be needed to balance the equation. The final result is

6 CO2 + 6 H2O = C6H12O6 + 6 O2 ,

where I dropped stoichiometric coefficient 1 of glucose, because, when it is just 1, it is customary not to write it explicitly, leaving it as understood.
