The identification of the acid radicals is first done on the basis of PRELIMINARY TESTS. DRY HEATING test is one of the preliminary tests performed EARLIER which may give some important information about the acid radical present.

ANSWER:

buffer solution (more PRECISELY, pH buffer or HYDROGEN ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. ... For example, the bicarbonate BUFFERING system is used to REGULATE the pH of blood, and bicarbonate also acts as a buffer in the ocean

Explanation:

B IRON(III) sulfate (or ferric sulfate), is a FAMILY of inorganic compound with the formula Fe2(SO4)3(H2O)n.

Answer:

The type of reaction is a displacement reaction.In this reaction , the highly reactive metal IRON replaces the Copper in copper sulphate by giving up two ELECTRONS and GETS oxidized and forms a new COMPOUND called ferrous sulphate.

EXPLANATION:

in an ionic compound the BOND is formed DUE to the transfer of electrons

ANSWER:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the DIFFERENCE between the mass number of the atom (M) and the atomic number (Z).

Answer:

1.In today's EXPERIMENT you will first determine Ka of an UNKNOWN acid by measuring the pH of the pure acid (no salt PRESENT). Next you will TITRATE the acid to FIND what volume of base is needed to neutralize it completely. each solution, you will calculate

Answer:

(i) The answer of the calculation

0.5785

0.02856×298.15×0.112

will contain 3 significant figures as 0.112 contains 3 significant figures which is the lowest number of significant figures.

(ii) The answer to the calculation 5×5.364 will contain 4 significant figures as 5.364 contains 4 significant figures which are the lowest number of significant figures. Here, the exact figure 5 is not CONSIDERED.

(III) The answer to the calculation 0.0125+0.7864+0.0215 will contain 4 significant figures as the result will be reported to 4 decimal places.

Answer:

A chemical equation is a shorthand description of a chemical reaction. The following equation describes the burning of hydrogen gas to FORM liquid water. 2H2(g) + O2(g) → 2H2O(l ) Chemical EQUATIONS give the following information about chemical reactions.

The CORRECT IUPAC name for Na2[FE(CN)5NO] complex is

sodiumpentacyanidonitrosoniumferrate(II)

                            or

sodiumpentacyanidonitrosyliumferrate(II)

*I think it should be Na2[Fe(CN)5NO] not Na2[CrF5NO] as there is no complex with this FORMULA

A reagent in chemical science is a “substance or compound that is added to a system in order to BRING a chemical reaction or is added to check whether a reaction is OCCURRED or not.” Such a reaction is USED to confirm the DETECTION of the presence of another substance

COORDINATION number – the number of NEAREST NEIGHBOR atoms or ions SURROUNDING an atom or ion. For FCC and HCP systems, the coordination number is 12. For BCC it's 8.

Answer:

A dot and cross diagram can MODEL the bonding in a SIMPLE MOLECULE : the outer shell of each atom is drawn as a CIRCLE. circles overlap where there is a covalent bond. electrons from one atom are drawn as dots, and electrons from another atom as crosses.

Explanation:

In graphite, each carbon atom is COVALENTLY BONDED to 3 other carbon ATOMS in a hexagonal planar structure. So, out of 4 valence electrons of carbon, THREE are used in covalent bonding; one spare electron with each carbon atom makes the graphite, a good CONDUCTOR of electricity.

Answer:

Sacrificial protection is a corrosion protection METHOD in which a more electrochemically ACTIVE metal is electrically attached to a less active metal. ... This reverts the protected metal BACK to its original form, and thereby PREVENTS it from CORRODING

Answer:

The molecular formula of HYDROGEN peroxide is H2O2 ; there are TWO H atoms and two O atoms in each MOLECULE.

Answer:

in this reaction A is LIMITING reactant because for a molecule of B it requires 3 molecule of A so 100 molecules of B requires 300 molecule of A but it is only 180 molecules . so A is limiting reagent
