Your QUESTION is not COMPLETED

At what temperature are Celsius and Fahrenheit the same?
The formulas for converting between degree Celsius and degree Fahrenheit are:
°F = (°C * 9/5) + 32
°C = (°F - 32) * 5/9
To FIND the temperature when both are EQUAL, we use an OLD ALGEBRA trick and just set ºF = ºC and solve one of the equations.
°C = (°C * 9/5) + 32
°C - (°C * 9/5) = 32
-4/5 * °C = 32
°C = -32 * 5/4
°C = -40
°F = (°F * 9/5) + 32
°F - (°F * 9/5) = 32
-4/5 * °F = 32
°F = -32 * 5/4
°F = -40
So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees.

I HOPE it can HELP you and PLEASE MAKE it BRAINLIST

Hey mate.....
of A pushes B and B pushes A with EQUAL and opossite force then they cancel the effect of each other means the between force will be ZERO....

They cancel the net force BECOZ they are equal and opossite.......


hope you understood....

Describe an experiment to show sublimation of a solid SUBSTANCE. ... When we worship God in our homes, we use a substance called camphor (in Hindi it is called कपूर). This camphor when subjected to heating, starts undergoing COMBUSTION and finally turns into GAS without becoming into LIQUID.

THANK YOU

no moles = given MASS / MOLAR mass

in 1 gm of NH3 there are = 1/17 = 0.05mol

similarly in 3 gm of CO2 there are = 3/44=0.06mol

so ratio is 5/6

Supramolecular chemistry may bedefined as "chemistry beyond the mole- cule”, bearing on the organized entities of HIGHER complexity that RESULT from the association of two or morechemical species HELD TOGETHER by INTERMOLECULAR forces.

A precipitate is a SOLID residue which falls at the bottom of the vessel,where reaction takes PLACE, after the reaction.
Any reaction that causes the formation of a precipitate is KNOWN as a PRECIPITATION reaction.

Hope it helps.. Please mark my ANSWER as brainliest.

Because the LPG is a GAS and the MOLECULES of LPG has intermolecualr SPACE. so it chatch tha fire FAST

In the presence of light, CHLOROFORM is oxidized by the air to form CARBONYL chloride or phosgene and HCl, which is HIGHLY poisonous. Thats why,it is KEPT or stored in colored bottle to prevent it from oxidization keeping away from light.

In GABRIEL phthalimide reaction, nucleophilic ATTACK of phthalimide to the carbon of alkyl halide takes PLACE, leading to the BREAKING of alkyl and halide bond and forming new carbon-nitrogen bond between alkyl and phthalimide. for the synthesis of aniline, arylhalide must be the reactant in place of alkylhalide. As we know it is difficult to break aryl and HALOGEN bond so nucleophilic substitution is difficult in aryl halide and hence aniline cant be formed using gabriel phthalimide reaction.

Because C6H5-CH2- is a aryl GROUP which is BENZYL. so when CHLORINE ATTACHED this called benzyl chloride

What do U MEAN by KANSA ...

Condition for FORMATION of covalent bonds are as FOLLOWS:
(i) The ATOMS should have high electron AFFINITY.
(i) The atoms should be non-metals.

SILVER SULPHIDE ( Ag2S)

Silver article TURNS black when kept in the air because silver article reacts with sulphur compounds such as hydrogen sulphide (H2S) PRESENT in air. The phenomenon is called corrosion. For silver PARTICULARLY, it is called tarnishing of silver

"A chemical BOND is a LASTING ATTRACTION between ATOMS, ions or molecules that ENABLES the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as inionic bonds; or through the sharing of electrons as in covalent bonds."

A HYPERVALENT molecule is a molecule that CONTAINS one or more main group elements apparently bearing more than EIGHT electrons in their valence shells. Phosphorus pentachloride (PCL5), sulfur hexafluoride (SF6), chlorine trifluoride (ClF3), IF7 are the examples of hypervalent molecules

ANSWER:-

Oxygen = 448 ml

MOLES produced =O2

22400 =448

=0.02moles

→2KCl+3O 2

POAC in Oxygen Atoms

Oxygen in KClO3 oxygen in O2

KClO3) = 3 moles of O2

(=3×0.022× 122.5x)

=0.06

x=0.03×122.5

x=3.675g

Answer=3.675g

Because it ALSO GIVES WATER after REACTING

With an odd number of ELECTRONS, at LEAST one atom in the molecule will have to violate the octet RULE.

PlZ GIVE the FULL QUESTION OTHERWISE I will not able to give you ANSWER .

It ABSOLUTELY is. But there are three nitrogen oxides:

N2ON2O nitrous oxide

NONO nitric oxide

NO2NO2 nitrogen dioxide

Each of these is a different compound and FOLLOWS the law of definite proportions.

But when nitrogen and oxygen combine under forcing CONDITIONS, all three oxides form.

since NAOH is MADE MOSTLY by electrolysis of brine (SALT water) Chlorine is also formed in it as a by product. it is also an industrially important material so they are CALLED Chlor-alkali industries

It disociate into sodium CARBONATE carbon di OXIDE and into WATER.
Hole it HELPS you

The number of ELECTRONS in an energy LEVEL is GIVEN by "Bohr-Bury formula"

which is 2n²

Therefore number of electrons in 4th energy level = 2(4)² = 2 x 16 = 32 e⁻

MAGNETIC MOMENT = N(n-2)

Answer: 24.5 grams of potassium chlorate.

Explanation:

According to avogadro's law, 1 mole of EVERY SUBSTANCE occupy 22.4 L at STP and CONTAINS avogadro's number of particles.

According to stochiometry:

2 moles of produce 3 moles of  

Thus of is produced from of

6.72 L of is produced from =of

Thus mass of potassium chlorate required to liberate of oxygen at STP will be 24.5 grams.

→2 Na + Cl₂ -----------> 2 NaCl

In the above equation, Chlorine exists as a diatomic gas, and thus its subscript 2 cannot be altered. Instead you'll have to balance, only by PLACING suitable coefficients to each participant in the above reaction.

Since there are 2 chlorine atoms on the reactants side, You MUST balance the number of chlorine atoms on either side by placing 2 in front of NaCl .

But then, we have 2 Sodium(Na) atoms on the products side which too can be balanced by placing 2 in front of Na on the reactants side.

→2 H₂ + O₂ -----------> 2 H₂O

If you get the first ONE, then there cannot be a problem balancing this one.

→N₂ + 3 H₂ -----------> 2 NH₃

There are 2 Nitrogen atoms on the reactants side, which means that we have to place a '2' in front of NH₃ in the product side in ORDER to balance the number of nitrogens;

Now as there are 6 hydrogen atoms on the products side, Place a '3' in front of H₂, so that there are 6 Hydrogen atoms on the reactant side too)

→N₂ + O₂ -------------> 2 NO

This one's the easiest as Balancing any one of nitrogen or OXYGEN will balance the whole equation.

→HCl + NaOH ----------> NaCl + H₂O

This is a simple acid-base reaction (also called neutralisation reaction), the reaction doesn't need to be balanced as it already follows the law of conservation of mass.

Hope it helps!!
