ANSWER:

Answer - IRON is the CORRECT answer .

Answer:

6.4*10^-4

Explanation:

Ka=Cα^2

Ka=0.10*(8/100)^2

Therefore Ka=6.4*10^-4

Explanation:

Decomposition is the process by which ORGANIC substances are broken down into simpler organic matter. The process is a PART of the nutrient cycle and is essential for recycling the finite matter that OCCUPIES physical space in the biosphere. Bodies of living organisms begin to decompose shortly after DEATH.

Answer:

MOLARITY= 5M

NORMALITY=10N

Explanation:

Molarity =

Normality= N×mol with

here n is the number of ionizable H ions

So, Normality=2× molarity

= 2×5

=10N

ANSWER:

Normality EQUAL to 10 to the power of -3.699 so molarity equal to 10 to the power of -3.699 DIVIDED by 2(dibasic acid)

ANSWER:

◆7-Neutral(WATER)

◆7-14-bases.

7 LEAST reactive acids as it decreases

it BECOME STRONGER but in bases 14 is most reactive .

Explanation:

A cyclic compound (ring compound) is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected to form a ring. Rings may vary in size from three to many atoms, and include examples where all the atoms are carbon (i.e., are carbocycles), none of the atoms are carbon (inorganic cyclic compounds), or where both carbon and non-carbon atoms are present (heterocyclic compounds). Depending on the ring size, the bond order of the individual links between ring atoms, and their arrangements within the rings, carbocyclic and heterocyclic compounds may be aromatic or non-aromatic, in the latter case, they may vary from being FULLY saturated to having varying numbers of multiple bonds between the ring atoms. Because of the TREMENDOUS diversity allowed, in combination, by the valences of common atoms and their ability to form rings, the number of possible cyclic structures, even of small size (e.g., <17 total atoms) numbers in the many billions.

Cyclic compound examples: All-carbon (carbocyclic) and more complex NATURAL cyclic compounds.

Answer:

Limiting REAGENT is A

As we know that by the eqn GIVEN

1mole of A reacts with 2 MOLE of B

so

5mol of a should react with 2×5=10 moles but there we have 20moles of B so A will finished firsts and LIMITS the reaction

the left 10mole of B left unreacted only 10 mol of B is reacted with 5 mol of B

Answer:

11

Explanation:

PH of HCL = 3

[H+] = 10^(-3)

It's given that molar concentration of HCl and NaOH is same. So, molar of concentration of OH- ion from NaOH is

[OH-] = 10^(-3)

POH = -log[10^-3] = 3

pH = 14 - 3 = 11

Answer:

Answer: 83.3 %

Explanation:

According to avogadro's law, 1 mole of EVERY substance OCCUPIES 22.4 L at STP and contains avogadro's number of particles.

To calculate the moles, we USE the equation:

1 mole of magnesium carbonate produce= 22.4 L of carbon dioxide at STP

Thus 0.06 moles of magnesium produce=

Thus percentage PURITY=

Therefore, the percentage purity of is 83.3%.

Answer:

In chemical bonds, an orbital overlap is the CONCENTRATION of orbitals on adjacent atoms in the same regions of space. Orbital overlap can lead to bond formation. The importance of orbital overlap was emphasized by Linus Pauling to explain the molecular bond angles observed through experimentation and is the basis for the concept of orbital hybridization. Since s orbitals are spherical (and have no directionality) and p orbitals are oriented 90° to each other, a theory was needed to explain why molecules such as METHANE (CH4) had observed bond angles of 109.5°.[1] Pauling proposed that s and p orbitals on the carbon atom can combine to form hybrids (sp3 in the case of methane) which are DIRECTED toward the hydrogen atoms. The carbon hybrid orbitals have greater overlap with the hydrogen orbitals, and can therefore form STRONGER C–H bonds.[2]

A quantitative measure of the overlap of two atomic orbitals ΨA and ΨB on atoms A and B is their overlap integral, defined as,

(the image is above-mentioned please note it.)

where the integration extends over all space. The star on the first orbital wavefunction INDICATES the complex conjugate of the function, which in general may be complex-valued.

Answer:

2.8

Explanation:

MULTIPICATION of 1/2.2

Hello beautiful..!!

It is given that,

2NO (g) + O2 (g) -------> 2NO2(g)

2vol : 1 vol ------> 2vol ( according to lussac's law)

•To CALCULATE amount of unused NO

NO : O2

2 : 1

X : 200

IMPLIES X = 400 cm^3.

TOTAL given nitrogen monoxide is 450 therefore 450 - 400 = 50cm^3.

• To calculate amount of NO2 formed :

O2 : NO2

1 : 2

200 : X1

Implies X1 = 400cm^3.

Therefore unused NO = 50cm^3 and amount of NO2 formed = 400cm^3

Therefore the total mixture composition is 450 cm^3.

Explanation:

the molar MASS of glucose is 180g/mole

90 MG = 0.09g

you have 0.1L

molarity = MOLES / liter

0.09g glucose / 180g/mole = 5x10^-4moles glucose

5x10^-4 moles / 0.1L = 5x10^-5M

A SALT with water of crystallization is called hydrated salt .

when an hydrated salt is heated it can lose its water of crystallization then it is called anhydrous salt

Answer:

1.Excited molecules may GET DEACTIVATED before they form products.

2. Excited molecules may LOSE their energy by COLLISIONS with non-excited molecules.

HYDRAULIC Washing.

This method is based on the differences in weight between the gangue and the metal.

GENERALLY, the metal particles of the ore are heavier than the impurities. So we use the PRINCIPLE of GRAVITY separation to separate the two.

It is a SINGLE DISPLACEMENT reaction where ALUMINIUM displaces magnesium to FORM magnesium chloride

Answer:

Metals are a common type of ductile MATERIAL. Copper, ALUMINUM, and steel are examples of ductile metals. The opposite of DUCTILITY is brittleness, where a material breaks when tensile stress is applied to lengthen it. Examples of brittle materials INCLUDE cast iron, concrete, and some glass products

➡️Calcination, therefore, is sometimes considered a process of PURIFICATION. A TYPICAL example is the manufacture of lime from limestone.

➡️In this process the limestone is BROUGHT to a temperature high enough to expel the carbon dioxide, producing the lime in a highly FRIABLE or easily powdered CONDITION.
