ANSWER:

Ionization, in chemistry and physics, any process by which ELECTRICALLY neutral atoms or molecules are CONVERTED to electrically charged atoms or molecules (ions). Ionization is one of the principal WAYS that RADIATION, such as charged particles and X rays, transfers its energy to matter.

Answer:

• Dobereiner could find only THREE TRIADS; . i.e total of 9 elements only. However the total NUMBER of elements were more than that of those ENCOMPASSED in Dobereiner's Triad. Thus, Dobereiner's could not be CLASSIFY most of the elements known at that time.

SIMPLE CUBIC UNIT CELL:

8 CONTRIBUTIONS from each vertex of the cube;

Total number of atoms in a simple cubic unit cell is:

BODY CENTRED UNIT CELL:

Apart from 8 contributions from each vertex , there is an additional whole contributions from the body centre.

Hence , total number of atoms:

FACE CENTRED UNIT CELL:

There are 8 contributions from each vertex and 6 contributions from each face of the cube:

Hope It Helps.

ANSWER:

========================

When ATOMS combine they gain, LOSE or share electrons in such a way that the outer shells become chemically complete. ... The valence of an element is the number of electrons the elements gain or loses when it forms compounds with other elements. Electrons in the outermost SHELL are CALLED valence electron.................

Answer:

Alcohols MAY be classified as primary, SECONDARY, or tertiary, according to which carbon of the ALKYL group is bonded to the hydroxyl group. Most alcohols are colourless liquids or solids at ROOM temperature

Answer:

Allylic halides are the COMPOUNDS in which the halogen ATOM is BONDED to sp3−hybridised CARBON atom next to carbon-carbon DOUBLE bond (C=C). Option D is allylic halide.

Heterogeneous mixture:

Heterogeneous MIXTURE consists of visibly difference substance or phases...... solutions have particles which are the side of atoms or molecules too small to be seen.

Homogeneous mixture:

Homogeneous mixture has home uniform appearance and composition throughout. Many Homogeneous mixture are commonly referred to as solution.

Answer:

When balancing chemical EQUATIONS, we FIRST need to count the different atoms on the reactants side and the PRODUCTS side. If the equation is not balanced, we need to use coefficients, which are numbers that we put in front of the substances reacting, to balance the equation.

ANSWER:

Dimethyl ETHER

Explanation:

The functional group of the given equation is O. So, it's an Ether. As there are TWO branches with only one Carbon, it's Methyl. Hence, according to the IUPAC RULES, it's Dimethyl Ether

Normality is MOLARITY *N factor
So molarity will no. Of moles per litre
It comes 0.1
Since the n factor is 1 its normality WOULD be 0.1

Answer:

Cryoscopic CONSTANT MAY be defined as the depression in FREEZING point when one mole of non-volatile SOLUTE is dissolved in one kg of solvent. It may also be defined as the molal depreesionconstant . ... It DEPENDS on the malar mass of the solute in the solution.

EXPLANATION:

The LAW of combining volumes was proposed by Gay-Lussac at about the same time that Dalton published his atomic theory. Shortly thereafter, Avogadro suggested the hypothesis that equal volumes of GASES contained equal numbers of molecules.

Answer:

For example, a TYPICAL carbon ATOM has six protons and six neutrons, and it has an ATOMIC weight of 12 amu. A carbon also has six electrons, but they are so small that they don't contribute to carbon's weight. An element is DEFINED by the NUMBER of protons in its nucleus.

SHELL , so , total no. of ELECTRON = 2+8+4= 14 = atomic no. and it is silicon . It's valency is 4 which is METALLOID.

Answer:

Sodium dichromate is the inorganic compound with the formula Na2Cr2O7. Usually, HOWEVER, the salt is handled as its dihydrate Na2Cr2O7·2H2O. Virtually all chromium ORE is processed VIA conversion to sodium dichromate and virtually all compounds and MATERIALS based on chromium are prepared from this salt.[1] In terms of reactivity and appearance, sodium dichromate and potassium dichromate are very similar. The sodium salt is, however, around twenty times more soluble in water than the potassium salt (49 g/L at 0 °C) and its equivalent weight is also lower, which is often desirable.[2]

Explanation:

It is produced at HIGH PRESSURE (1000-3000 bar; 80-300°C) VIA free radical polymerization process. The LDPE is composed of 4,000-40,000 carbon atoms, with many short branches. Two basic processes used for the PRODUCTION of LOW density polyethylene: stirred autoclave or tubular routes
