Explanation:

The central metal or the metal ATOMS in coordination compounds show TWO types of VALENCY. ... The number of secondary valences is fixed for every metal atom. It means that the coordination number is fixed. The metal atom works towards SATISFYING both its primary and secondary VALENCIES.

2-amino-3-hydroxypropanoic ACID is the IUPAC name of CH3 CH(NH2)CH(OH)COCH=CH-COOH.

Answer:

Yes, Hydrochloric gas comes out from the test tube.

The following reaction took place.

2NaCl(s) + H2SO4(l) - NA2SO4(aq) + 2HCl(g)

When tested with DRY litmus paper, it's colour do not change but when it is tested with a wet litmus paper, it's colour changes from blue to red DUE to the formation of hydrochloric acid on the litmus paper.

(i) From the above activity we infer that Dry HCl gas do not shows it ACIDIC behavior due to the absence of water.

(II) HCl solutions shows it's acidic behavior as it is dissolved in water and dissociates into H+ and Cl- ions. Out of these, H+ ions are responsible for it's acidic behavior.

Hope you understand.

The heating element of the HEATER BLOCKS the electric current and does not let it pass. So the heating element gets heated and GLOWS due the heat. It has HIGH resistivity , so it does not melt. The cord of the electric heater is a good conductor of electricity so it does not get heated up and also does not glow.

Answer:

A plasma is a gas that has been energized to the point that some of the electrons BREAK FREE from, but travel with, their NUCLEUS. Gases can become PLASMAS in several ways, but all include pumping the gas with energy. A spark in a gas will CREATE a plasma.

Esters have the general FORMULA RCOOR′, where R MAY be a hydrogen atom, an ALKYL group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom. (If it were hydrogen atom, the compound WOULD be a carboxylic ACID.) The esters shown here are ethyl acetate (a) and methyl butyrate

Answer:

Ethane (CHCH), being just an alkane, will not REACT with the water or the acid, as ethane has no REACTIVE sites. However, ETHENE (a.k.a. ethylene) (CH=CH), having an electrophilic double bond, will react with water in the presence of an acid catalyst to form ethanol (if I'm not mistaken).

ANSWER:

Mass of H2O = 1170 g or 1.170 kg

Explanation :

Refer the ATTACHED picture.

IONIC Bonds

In an ionic bond, one atom essentially donates an electron to stabilize the other atom. In other words, the electron spends most of its time close to the bonded atom. Atoms that participate in an ionic bond have different electronegativity VALUES from each other. A POLAR bond is formed by the attraction between oppositely-charged ions. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt. You can predict an ionic bond will form when two atoms have different electronegativity values and detect an ionic compound by its properties, including a tendency to dissociate into ions in water.

Covalent Bonds

In a covalent bond, the atoms are bound by shared electrons. In a true covalent bond, the electronegativity values are the same (e.g., H2, O3), although in practice the electronegativity values just NEED to be close. If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar. Usually, an electron is more attracted to one atom than to ANOTHER, forming a polar covalent bond. For example, the atoms in water, H2O, are held together by polar covalent bonds. You can predict a covalent bond will form between two nonmetallic atoms. Also, covalent compounds may dissolve in water, but don't dissociate into ions.

To a suspension of 1.58 G (10 mmol) of Bis(diformylamino)methane in 20 ml of benzene, 5.35 g (40 mmol) of aluminum chloride was added at 20°C. The mixture was stirred for 66 H at the same temperature. The mixture is poured slowly under stirring in 500 ml of water. After stirring for one HOUR, a steam distillation is carried out. The resulting distillate is extracted twice with 50 ml of CHLOROFORM. The combined organic phases are dried with sodium sulfate. After filtering off the drying agent, the organic solvents were removed in vacuo and the residue was fractionally distilled. YIELD: 1.5 g (71%) of colorless liquid. Bp. 180°C; nD20 = 1.5440.

Goldsmith used the solution called Aqua regia.

• Aqua regia is a solution which is called as royal water in Latin.

• It is the mixture of concentrated Hydrochloric acid and concentrated nitric acid in the ratio of 3:1.

• Aqua regia is CAPABLE of dissolving NOBLE metals like gold and platinum. When upper-layer of DULL gold ornament is DISSOLVED they lose their weight.

no PROBLEM....

Answer:

Correct order of electron affinity is :

Ar < Na

Since, Ar has greater size as compared to P & Na which have SMALLER, so electron affinity will be LARGER for small size atom.

As Na has LESS protons as compared to P, hence Na has less attraction to other ATOMS. THEREFORE, Na has less electron affinity than P.

• So when Carbon DIOXIDE is passed through lime water, an Acid-Base REACTION takes place producing salt and water. The reaction is written as, Calcium CARBONATE is insoluble in water, thus forming white precipitate, making the solution appear MILKY. This also serves as the classic test for carbon dioxide.

ANSWER:

Answer:

The relative reactivity of a GROUP of metals can be established by comparing the reaction of each metal with a given reagent. A metal might react with a specific reagent or no reaction may occur. On the other hand, a given metal might react with a specific reagent at a different rate than some other metal.

In this experiment, the reaction of a group of metals with dilute hydrochloric acid will be used to determine the relative reactivity of the metals. Some metals react with dilute hydrochloric acid as shown in Equation (1).

(Equation. 1) M(s) + 2 HCl(aq) ---> MCL2(aq) + H2(g)

At the same time, the rate at which different metals react with dilute hydrochloric acid will vary. Thus, from the laboratory observations as to whether a gas is formed and if so at what rate the gas is evolved, the relative reactivity of the metal can be determined.

A second reaction to be studied in this experiment is the reaction of each of a group of metals with solutions of their corresponding SALTS. Some metals will react with a solution of a salt of another metal as indicated in Equation (2).

(Equation. 2) M(s) + FeSO4(aq) ---> MSO4(aq) + Fe(s)

In this case, the FACT that a metal does or does not rect with a solution of another metallic salt can be used to establish the order of reactivity of a group of metals
