C+O2=CO2(CARBON DIOXIDE)

first step is substitution by azide ion and 2nd step is reduction.Gabriel method . Phthalimide is used.excess AMMONIA is used to get more PRIMARY amine OTHERWISE secondary and TERTIARY amine will PRODUCE predominantly.Explanation:

A.is the ANSWER for this QUESTION

:-It express in a RATE expression indicates the decrease in concentration of the REACTANT with time. It is the MINUS sign which is used to show the decrease in concentration of the reactant.

Answer:The particles that exist inside the nucleus are PROTONS and NEUTRONS but only proton has the positive charge equal to 1.so, the CORRECT answer is protonhope it HELPS YOUPLZ mark as brainliest

I will give you ANSWER LATER TODAY or tomorrow MORNING

are you I am THINKING you are FINE

HERE'S YOUR ANSWER. HOPE IT HELPS YOU. PLEASE MARK IT AS THE BRAINLIEST.

Carbon DIOXIDE is produced whenever an acid. REACTS with a carbonate. This makes carbon dioxide easy to MAKE in the laboratory. Calcium ...

Adding or removing energy from MATTER CAUSES a physical CHANGE as matter moves from one state to another. For example, adding thermal energy (heat) to liquid water causes it to become steam or vapor (a GAS). And removing energy from liquid water causes it to become ice (a solid).Most liquids contract as they freeze.Explanation:Hope it HELPS you

of Conservation of Mass dates from Antoine LAVOISIER's 1789 discovery that mass is neither created nor DESTROYED in CHEMICAL reactions. ... Lavoisier's finding laid the foundation for modern chemistry and revolutionized science.

stries, ETHANOL is prepared from molasses. Molasses are residues when SUGAR cane is PROCESSED while producing sugar from it.During fermentation, first sucrose is converted into glucose and fructose by enzyme invertase and then glucose is converted into ethyl alcohol.Hᴏᴘᴇ ɪᴛs ʜᴇʟᴘs ʏᴏᴜ ❤

:The heat of NEUTRALIZATION of a week acid (HX) and strong BASE (MOH) is -11.2kcal/mol .then the heat of DISSOCIATION of weak acid is 2.5 kcal/mole EXPLANATION: Heat of formation of water is 13.7 kcal Thus,       kcal/mole GIVEN that heat of neutralisation of HX by strong base MOH is -11.2 kcal/mole Therefore,      kcal/mole Adding both the equations      kcal/mole Therefore, the heat of dissociation of weak acid is 2.5 kcal/mole Hope this answer is helpful.

rate-limiting step The slowest step in a metabolic pathway or series of CHEMICAL reactions, which determines the overall rate of the other reactions in the pathway. In an ENZYMATIC reaction, the rate-limiting step is generally the stage that requires the GREATEST activation energy or the transition state of highest FREE energy.Explanation:

tion:iv) Sulphur + NITRIC Acid (conc.) Sulphuric acid + WATER + Nitrogen dioxidehope it helps youif it is WRONG then sorry

the ALKALI METALS are so REACTIVE

The BOHR model was a ONE-dimensional model that pre-owned one quantum number to portray the circulation of electrons in the iota. The LONE data that was significant was the SIZE of the circle, which was depicted by the N quantum number.

e/m of positive particles DEPENDS on the nature of gas taken INSIDE the DISCHARGE tube because positive particles are ions of gas molecules whose charge and mass VARY in accordance with their mass and charge they obtain

's FIRST law of ELECTROLYSIS states that the mass of material deposited on or eroded from an electrode is DIRECTLY proportional to the amount of charge PASSING through the ELECTROLYTIC cell.Hᴏᴘᴇ ɪᴛs ʜᴇʟᴘs ʏᴏᴜ ❤

nch of SCIENCE CONCERNED with the substances of which matter is composed, the investigation of their properties and REACTIONS, and the use of such reactions to FORM NEW substances.

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of TWO ways: Either the air is COOLED to its DEW point or it becomes so SATURATED with water vapor that it cannot hold any more water.

ication is the process when a MOLTEN liquid BECOMES a solid. In the solidification of water to ice without sublimation, there is an increase in volume. The temperature fell SLOWLY during the COOLING until solidification of the melt BEGAN to take place.

Explanation:In 1900, EDWIN A. Hill devised a system of writing a CHEMICAL formula that is used for a large number of compounds today. The Hill system states carbon atoms are listed FIRST, hydrogen atoms next and then the number of all other elements in ALPHABETICAL order.

solid: Has a definite shape and VOLUME. liquid: Has a definite volume, but TAKE the shape of the container. gas: Has no definite shape or volume. change of state: When matter is converted from one of the three states (example: solid, liquid, or gas) to another state.Explanation:PLS MARK AS BRILLIANT AND PLS FOLLOW

tion:B) sodium HYDROXIDE hope this is HELPFUL for you

Zinc is more ELECTROPOSITIVE than Iron but it does not GET corroded faster and is used to galvanize iron. Reasons: A thin layer PREVENTS the entering of water and oxygen UNDERNEATH. Zinc is more reactive than iron.Explanation:

Generally, when metals are treated with MINERAL ACIDS, hydrogen gas is liberated but when metals (except Mn and Mg) are treated with HNO3, hydrogen is not liberated, why? Nitric acid (HNO3) is a strong oxidising agent. ... So, in the REACTION of metals (except Mn and Mg) with dilute nitric acid, no hydrogen gas is EVOLVED.
