Neutralization is a type of chemical REACTION in which a strong acid and strong base react with each other to form water and salt. Have you EVER been unlucky enough to be stung by a wasp or a bee? Bee stings are acidic in nature, which is why a household remedy for a bee STING is baking soda or sodium bicarbonate, which is a basic substance. A wasp sting, on the other hand, is mildly basic, so a household remedy for this will be vinegar, also known as acetic acid. These SIMPLE treatments ease these painful stings by a process called neutralization.

Usually we come across anomalies in the TRENDS of periodic properties for example the size [Atomic radius value from Raymond CHANG Chemistry 9th Edition] of Gallium (135 pm) is smaller than Aluminium (143 pm) as opposed to the basic trend that atomic size increases down the group. This is usually attributed to the fact that the poor shielding of nuclear charge by intervening D orbitals leads to a GREATER Zeff hence the radius is less as opposed to the trend.

If that's the reason why don't we observe similar effects for other groups like group 15 having Phosphorus (110 pm) and ARSENIC (120 pm) [Here the size doesn't increase much but is still significant as compared to changes taking place in group 13] , where the size actually increases even when there are D orbitals to intervene. Or in short why are the effects so profound for group 13 and not the other members?

There's another example of In (166 pm) and TL (171 pm). Both belong to group 13. As compared to other groups these two members have the lowest increase in atomic radius.

Hello mates

Taking m = 1 a.m.u. = 1.66 × 10-power24kg,
and C = 3.0 × 108 m/s

We get, E = (1.66 × 10-power24) (3.0 × 108) J

= 1.49 × 10-power 10 J

As 1 MEV = 1.6 × 10-13 J

Therefore, E = 1.49 × 10-10/106 × 10-power24 MeV

= 932.26 MeV

I hope this process will Help you

First of all! Let's CONVERT 293 K into C

t°C = t°K - 273
C = 293 - 273 or 20°C

So, we know that 20°C is approximately room temperature and will not create any different in SATURATION level.

Now,

Mass of solute = 36g

Mass of solvent = 100g

Mass of solution = 36g + 100g = 136g

Concentration = [ ( 36 / 136 ) × 100 ]%
= 26.47%

HOPE it helps

1) solid have definite VOLUME and definite shape.

2)GASES have definite volume and no definite shape.

3) Gases are highly compressible.

4)Gas

5)Intermolecular space is MAXIMUM in gases.

6)Intermolecular space is maximum in solids.

Hund's rule of maximum MULTIPLICITY states that if two or more orbitals of same energy are available, electrons first fill the available orbitals singly and then PROCEEDS to fill them in pairs.

Examples:

Carbon: Its electronic configuration is 1s2 2s2and 2p2

In, P there are three orbitals of equal energies. So, the electrons will first fill them singly. So, two orbitals have one electron each INSTEAD of one orbital having 2 electrons.

Fluorine: Its electronic configuration is 1s2 2s2and 2p5

In, p there are three orbitals of equal energies. So, the electrons will first fill them singly. So, three orbitals get FILLED by one electron and then they are filled in pairs. So, two orbitals have paired electrons and one orbital has a singly filled orbital.

→ 1 mole of (NH4)3PO4 will contain 12 mole H- atom

→ So, 3.18 mole of H-atom will be PRESENT in

→ 1/12 × 3.18 moles of (NH4)3PO4

= 0.265 moles of (NH4)3PO4

→ 1 mole of (NH4)3PO4 contains 4 moles of H-atom.

→ So, 0.265 (NH4)3PO4 will contain

→ 4×0.265 = 1.06 moles of OXYGEN atoms.

I MOLE ACETIC ACID contains (12+3+12+16+16+1) gm Acetic Acid
i.e 60 gm acetic acid = 1 mole
Hence, 1.5 gm acetic acid= 0.025 mole

EMPIRICAL FORMULA of BENZENE is ( CH)n

Answer: 1) Mg

Explanation:

Ionization energy is defined as the energy required to REMOVE an electron from an ISOLATED GASEOUS atom.

This energy will be higher for fully filled and half-filled electronic configuration than partially filled electronic configuration. This is so because half filled and fully filled CONFIGURATIONS are stable.

Mg: 12:

1. Magnesium has fully filled s orbital and thus first ionization potential is higher .Thus, first ionization potential will be higher.

After loss of one electron, the second electron will be lost easily as it will acquire inert gas configuration after loss of second electron.

Thus 2ND IP < 1st IP for magnesium.

2. Ne: 10:

Neon has fully filled 'p'-orbital. Thus, first ionization potential is higher.

3. C:

Carbon has partially filled 'p'-orbital. Thus, first ionization potential will be lower.

What is your QUESTION PLEASE EXPLAIN

The COMPOSITION of MATTER REMAINS same in PHYSICAL CHANGE

(i)Boiling point - higher the boiling point, SLOWER the rate of evaporation.
(ii)Temperature - Higher the temperature, higher the rate of evaporation.
(iii)Surface area - Larger the surface area, higher the rate of evaporation.
(iv)Wind velocity - In airy place evaporation TAKES place faster.
(v)HUMIDITY - In humid air, very LITTLE evaporation takes place, while in dry air rapid evaporation takes place.

A continuous spectrum is a record FORMED by collecting light of all frequencies TRAVELING through space together.

A LINE spectrum is a record formed by collecting light emitted from excited atoms whose electrons are falling back down to LOWER energy states.

Because plastic DONOT DECOMPOSE easily and creates pollution in the environment. They choke the drains and if animals or birds EATS the plastic they will die.

carbon monooxide MOLECULE,carbon(C) has 4 valence e- and oxygen( O) has 6 e-.Thus total no. of valence electrons will be 10e-.If single bond is formed between C and O,to complete the octet of oxygen ,then remaining two electrons are the LONE pair on C-atom.
C ----O(SINGLE BOND),this will not complete the octet on carbon.So in this WAY it does not obey the octet rule.But triple bond is formed between C and O.There will be shairing of total 6E- between carbon and oxygen,thereby satisfying octet of both the atoms.

[Here the Size doesn't increase much but is still significant as COMPARED to changes taking place in group 13] where the size actually increases even when there are D orbitals to intervene.


There ANOTHER example of Indium{166 pm} and Titanium {171 pm} both belong to Group 13.
As compared to other these Two Members have the Lowest increase in Atomic Radius.

Manufacturing synthetic fibres is actually helping in conversation of FOREST because synthetic fibres are MADE from CHEMICALS these are not made about the NATURAL resources such as wood etc so that's why the conserve the forest

Hey MATE!!

HERE IS THE ANSWER

QUESTION __________________

➡why are plastic bottles commonly USED to STORE chemicals in the laboratory?

ANSWER _________________

➡plastic bottles are commonly used to store chemicals in the laboratory because as plastic is non-reactive that is they do not react with other substances or chemicals.


Hope it helps to you.

Thanx

Synthetic fibers are more DURABLE than most natural fibers and will readily pick-up different dyes. In addition, many synthetic fibers offer consumer-friendly functions such as STRETCHING, waterproofing and stain resistance. Sunlight, moisture, and OILS from human skin cause all fibers to break down and wear away.

Let the mass of the solution be 100gm

So mass of urea is 20% of 100,so mass of urea is 20 gm

So mass of water = 100 – 20

= 80gm

So mass of urea by SOLVENT(water) = 20 X 100

-------

80

= 25%

so the answer is 25%

Since it has made from CHEMICAL TREATMENT of wood PULP it SMELLS LIKE burning of paper during burning.
