applying a zinc coating over it

Explanation:

as IRON REACTS with air to form iron oxides or RUST, zinc doesn't REACT with Oxygen and prevent air from REACHING the iron layer and hence no rusting occurs.

Answer: I think the answer is——> 4-bromo,1 (4,4-dimethylpent-2-ene)benzene

Explanation:

Bromine is a halogen GRP member and hence, ALWAYS prefixed.

It has less PRIORITY than C=C.

The reason why we wouldn’t consider the long carbon grp (with the DOUBLE BOND) as the parent chain is because it has less no. of carbons than in the benzene ring.

Answer:

As we know the formula for KNOWING the number of electrons in a SHELL it is 2n^2.

So the electronic configuration is 2,8,7

Therefore the 17th electron will be ACCOMMODATED in the third energy shell.

The HYDROGEN ions have no effect on the activation ENERGY of the reaction.

NEWTON's laws of motion relate an object's motionto the forces ACTING on it. In the first LAW, an object will not change its motion UNLESS a force acts on it.In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer:

in chemistry, canonical STRUCTURES is a way of representing or describing the delocalized electrons within certain molecules or polyatomic ions (LIKE is SULFATE, phosphate ions) where the bonding cannot be expressed in terms of single LEWIS structure.A "canonical structure" is also known as a resonance structure, i.e. one of POSSIBLY more than one contributing structures that combine to produce the true, resonance hybrid structure.

Answer:

When a CONCENTRATED solution of SODIUM chloride is electrolysed, it decomposes to form sodium hydroxide, chlorine and hydrogen

Chlorine gas is formed at anode (positively charged) and hydrogen gas at cathode (negatively charged)

The REACTION takes PLACE is given as:

2NaCl + 2H2O → 2NaOH + Cl2 + H2

Carbon is one of the most prevalent elements which constitute all forms of LIFE on Earth. Like water, carbon undergoes a natural cycle of formation and disintegration. It shows how carbon atoms are CAPABLE of existing in different compounds in different phases of time.

Step 1 :- Carbon enters the atmosphere in the form of carbon dioxide (gaseous state), due to RESPIRATION (from microorganisms and other lifeforms) and combustion.

Step 2 :- Carbon dioxide is absorbed by plants to manufacture GLUCOSE (which consists of 6 carbon atoms) with the help of photosynthesis.

Step 3 :- Animals consume these plants, thus the carbon compounds in the latter pass along the food chain. Most of the carbon they consume is EXHALED as carbon dioxide that was formed during aerobic respiration. The animals and plants eventually die.

Step 4 :- In case of dead plants, decomposers break them down. This leads to the return of carbon to the atmosphere, as the decomposers now carry it within their bodies and exhale it. If decomposition does not occur, the plant and animal material eventually transform into fossils over a span of centuries.

The volume of nitrogen in the mixture is:

10% of the mixture  =   10/100 X 1 liter

                                =    0.1 LITERS

Use ideal GAS law to calculate the moles of the nitrogen gas.

Ideal gas law states that 1 MOLE of an ideal gas occupies 22.4 liters by volume.

Therefore, If 22.4 liters gives 1 mole,

                  then what will 0.1 mole give?  =  ( 0.1 x1/22.4) liters.

                               (use cross MULTIPLICATION to come up with the answer)

                                              = 0.1/22.4

                                              = 4.46 x 10^-3

Properties of Bleaching Powder (Calcium oxychloride).

(i) It is a pale yellow powder. It has a strong smell of CHLORINE. (ii) It is soluble in water but a clear SOLUTION is never formed due to presence of impurities. (iii) It LOSES chlorine by the action of carbon dioxide.

Uses of Bleaching Powder

Uses of Bleaching PowderIt is USED for bleaching dirty clothes in the laundry, as a bleaching agent for cotton and linen in the TEXTILE industry. It is a strong oxidizing agent hence used as an oxidizer in many industries. It is used as a disinfectant which is used for disinfecting water to make potable water.

EXPLANATION:

Answer:

Addition reactions are TYPICAL of unsaturated organic compounds—i.e., alkenes, which contain a carbon-to-carbon double bond, and alkynes, which have a carbon-to-carbon triple bond—and aldehydes and ketones, which have a carbon-to-oxygen double bond. An addition reaction may be visualized as a process by which the double or triple bonds are FULLY or partially broken in order to ACCOMMODATE additional atoms or groups of atoms in the molecule. Addition reactions to alkenes and alkynes are SOMETIMES called saturation reactions because the reaction causes the carbon atoms to become saturated with the maximum number of ATTACHED groups.

consider a full sphere of radius 21 cm.

what is the perimeter of that full CIRCLE?

it is 2 pi R

= 42pi

now, we know a full circle has an ANGLE 360

so a sector having angle 120 is (120/360) of a complete circle right? ( I just took the ratio of the angle of sector to the angle of the sphere)

120/360 = 1/3

so sector = 1/3 x full circle

therefore perimeter or circumference of the sector = 1/3 x perimeter of circle

= 1/3 x 42pi

=14pi = 14 x 3.14 = 43.96 =44.0

To liquefy a GAS we need to bring the gas MOLECULES together very close to each other. This is achieved by compressing them using high pressures. At very high pressures, the boiling point of the liquid rises. So at practically achievable temperatures, the GASES can liquefy and EXIST as liquids.......
