Hola!!!

HERE IS THE ANSWER

✔An atom is the smallest PARTICLE of an ELEMENT that can take PART in a chemical reaction .

✔Democritus gave the term "Atom".


Hope it helps to you.

Hey frnd here is UR ANS....

S + 6HNO3 = H2SO4 + 6NO2 + 2H2O

Hope it HELPS you✌✌

Thankyou☺☺

The RATIO of masses of a molecule is the LAW of MULTIPLE PROPORTION

First calculate the molar concentration of CO2by  USING the Henry’s law.



Here, K is the Henry law constant and P is the partial pressure of CO2.



The carbonate ion reacts with water to produce HCO3−, which is the conjugate base of H2CO3. Construct an equilibrium table for each ionization, using X as the unknown in the first ionization and y as the unknown in the second ionization.
I Hope this is helpful for U....

this is that the inter MOLECULAR spaces and the force of ATTRACTION between the molecules of gases is MUCH more and much less RESPECTIVELY than the other STATES of matter.

This is iodoform REACTION.(MAINLY answered by methyl KETONES and methyl carbinols)

Since sodium propanoate is LIBERATED here, the ketone will be butan-2-one.

Ans-Butan-2-one

This is because fire needs AIR or better to say oxygen to BURN which is PRESENT in the air. So when a person's clothes catches and when he starts running , the SUPPY of air increases the the fire increases and the person dies.

The CELL MAY get shrinked. DUE to the PROCESS of ENDOSMOSIS

Here MARK as BRAINLIEST ANSWER

Mixture
it is MADE up of 2 or more TYPE of matters
Elements
it is only made up of 1 type of MATTER

A molecule is the smallest particle of a substance that exists independently. Molecules of most ELEMENTS are MADE up of only ONE of atom of that element. Oxygen, along with NITROGEN, HYDROGEN, and chlorine are made up of two atoms. ... A compound is a substance formed when two or more elements are chemically joined.

2- quantum numbers
3- ATOMIC STRUCTURES by various scientists (don't go for every STRUCTURE DEEPLY. just take an over look as modern structure is more important.
4- shape of orbitals
5- DUAL nature of matter.

Because FIRE NEED oxygen to burn and produce gases LIKE Carbon MONOXIDE and carbon dioxide which CAUSE global warming . CO is very dangerous for health

1.potash alum K2SO4.(Al2SO4)3.24H2O 2.mohr's SALT FeSO4.(NH4)2SO4.6H2O Complex salt: 1.HEXA ammine cobalt (III) sulphate (cationic complex) [Co(NH3)6]SO4 2.potassium hexa cyano ferrate (II) (anionic complex) K4[FE(CN)6]

Because LPG never form any smoke or unburned hydrocarbons. LPG are COMPLETELY burnt substances. In wood it leads to a LOTS of air pollution and HEALTH related hazard but LpG doesn't lead to any problems. so LPG are better domestic fuels.

Hi FRIEND the answer is as FOLLOWS.

Clean environment MAKE's our HEALTH good.And if PEOPLE try not to clean our environment it may CAUSE MANY serious disease.

to PREVENT them from RUSTING

Combustion of fuels like PETROLEUM causes formation of un-burnt carbon particles along with carbon monoxide gas. These harmful POLLUTANTS ENTER the air and cause respiratory diseases.
