1.Name the acid present in the following:
(i) Tomato (ii) Vinegar (III) Tamarind
Answer. (i) Oxalic acid (ii) Acetic acid (iii) Tartaric acid

2.15 mL of water and 10 mL of sulphuric acid are to be mixed in a beaker
(i) State the method that should be followed with reason.
(ii)What is this process called?
Answer.
(i) The acid is to be added slowly in water to prevent the mixture to be splashed. The
reaction is highly EXOTHERMIC, therefore, constant cooling should be done.
(ii)The process is called dilution.

3. Explain how antacid works.
Answer. Hyperacidity is caused by EXCESS of hydrochloric acid in STOMACH. Antacid is basic in nature. It neutralizes excess of acid and gives RELIEF from pain caused by hyperacidity.

Yes! sugar is SOLID and salt is FINE solid particles we can SAY and it doesn't takes the shape of JAR the only THING is that the molecules of sugar and salt tries to adjust themselves in the container/jar .thus, resembling the shape of jar.

It is 10^(-7) TIMES more ACIDIC

Because dilute SUBSTANCES
are LESS REACTIVE than concentrated one.

Hi
here is your answer

The enthalpy of neutralization of a STRONG acid and a strong base (for example HCl and NaOH) is around 57.9 KJ/mol.

(The enthalpy of neutralization is always expressed per mole of water formed).


HOPE it helps U dear...
if it did then plz MARK as brainliest...!!!

Hey!!!

That's EASY

=> HCl(ACID) + NaOH(base) ==> NACL. + H2O

Hope this helps

In SOLID the MOLECULAR are PACKED

It is a salt formed USING a strong acid -HCl and a strong base BA(OH)2, hence its pH should be somwhat close to 7 (NEUTRAL pH in SOLUTION). PH of barium chloride is 7 because it is a salt obtain by combination of a strong acid(HCl) and a strong base barium HYDROXIDE

The charge-shift bond has been proposed as a new class of chemical bond that SITS alongside the two familiar families of covalentand ionic bonds where electrons are shared or transferred respectively.[1][2] The charge shift bond derives its stability from the resonance of ionic forms rather than the covalent sharing of electrons which are often depicted as having electron density between the bonded atoms. A feature of the charge shift bond is that the predicted electron density between the bonded atoms is low. It has LONG been known from experiment that the accumulation of electronic charge between the bonded atoms is not necessarily a feature of covalent bonds.[3] An example where charge shift bonding has been used to EXPLAIN the low electron density found experimentally is in the central bond between the INVERTED tetrahedralcarbons in [1.1.1]propellanes. Theoretical calculations on a range of molecules have indicated that a charge shift bond is present, a striking example being fluorine, F2, which is normally described as having a typical covalent bond

Carbon has been used traditionally in many forms, to name a few charcoal; POWDER; activated pellets; carbon cloth; for water TREATMENT but there have been various problems associated with their use. Carbon aerogel (CA) is comparatively new form. It has large surface area because of its ultra-micro-porous structure; it also has high conductivity which is suitable for capacitive de-ionization (CDI) technology. CA electrodes were used in CDI for metal ions, bacteria, and some organic pollutants removal. The problem is once these electrodes are used and saturated they lose their capacity for removing ions and they need to be replaced. CA is expensive and REPLACEMENT of CA electrodes increases the cost of water treatment for this reason they needs to be regenerated. Regeneration studies by various researchers so FAR involves equal or more amount of clean water than the amount of water treated by it. In addition to this cost estimation for this process has not been done extensive. This study investigates various methods to regenerate CA electrodes to reduce the amount of water involved. To predict desorption behavior in a better manner a model is to be prepared.

Heat can GET through the THINNER layers EASIER than it would through the solid veg

The purpose of the deoxynucleotide triphosphates (DNTPS) is to SUPPLY the “bricks.” SINCE the idea behind PCR is to synthesize a virtually unlimited AMOUNT of a specific stretch of double-stranded DNA, the individual DNA bases must be supplied to the polymerase enzyme.

A DOUBLE salt is FORMED between TWO simple salts by crystallization from a saturated solution of a mixture of the two. Examples  

K2SO4.Al2(SO4)3.24H2O ( potash Alum), 
 

(NH4)2 Al2(SO4)3.24H2O (Ammonium Alum) 

 FeSO4(NH4)2 SO4.6H2O (Mohr’s Salt)

A DESAPHALTING PROCESS IN WHICH A RESIDUAL OIL HAVING A VISCOSITY ABOVE ABOUT 2500 S.S.U. AT 210* F. IS ADMIXED WITH A DEASPHALTING AGENT CONSISTING ESSENTIALLY OF PROPANE AND BUTANE IN WHICH THE SAID BUTANE COMPRISES ABOUT 14% BY VOLUME OF THE DESAPHALTING AGENT.

The ACCIDENTAL touch of nettle LEAVES creates a burning SENSATION because it injects formic acid, acetylcholine and histamine when its cell sap are under pressure.
Even the slightest touch breaks off their little tips, the broken tipthen forms a sharp edge, which pierces the STINGING HAIR into the skin and then sensation happens

The time interval for the reaction should be of the order of milliseconds.Acetylene may be PRODUCED from avariety of hydrocarbon FEED stocks (natural gas, LPG, naphtha, fuel oil, even CRUDE oil) by high-temperature cracking. ... The process is known as Sachasse process using natural gasas raw material

Adsorption at the Liquid–Solid Interface: Thermodynamics and Methodology

Françoise Rouquerol, ... Kenneth Sing, in Adsorption by Powders and Porous Solids, 1999

Definition of DISPLACEMENT ENTHALPIES (and energies)

The enthalpies of adsorption as already defined are adequate for an experiment when a clean adsorbent is immersed in the solution, but they are not suited for other experiments, which are usually more accurate where the adsorbent is initially immersed in the pure solvent. When the pure solvent is replaced by a solution of molality b2, adsorption of the solute can only take place by displacement of the solvent. The word ‘displacement’ is used here to indicate that the adsorption of the amount n2σ(n) of solute produces the DESORPTION of a corresponding (but usually not equal) amount of solvent. Following Kiraly and Dekany (1989), let us call r the amount of solvent displaced (i.e. desorbed) by one mole of solute, therefore producing a change in composition of the solution and giving an ENTHALPY of mixing, ΔmixH, which is part of the overall heat effect, Qexp, measured during the experiment. It is preferable not to INCLUDE ΔmixH (which is not a property of the interface) in the definition of the enthalpy of displacement, which is therefore:

(5.70)Δdp1H1.2=Qexp−ΔmixH

Hi there!

As the surface area increases, more NUMBER of molecules will ESCAPE per unit time.

THEREFORE, rate of evaporation increases.

But vapour PRESSURE in nothing but pressure and is defined as force per unit area.

Hope it HELPS!

This PROCESS is CALLED SUBLIMATION

It is BASED on the CONCENTRATION of ELECTROLYTES

Because the WATER of COOLER is EASILY EVAPORATE,,and so we feel cool.

Some empty SPACE's R left between the water PARTICLES .Due to this,the density of ICE becomE's less than water .As a result ,ice floats on water.
hope it helps☺☺

Just GOOGLE it,,,,SIR JI

We can SAY that SUBSTANCE A is SOLUBLE in WATER

It's PRESENT in the CLOUDS

How the HELL do I KNOW that?

Hey mate here is your answer....
............... ..............
The subject of carbon COMPOUNDS iscalled ORGANIC chemistry because all known organisms, or living THINGS, are made up of water and carbon compounds.

hope it will help you my dear friend PLZ mark it as BRAINLIEST I need it.

Homonuclear DIATOMIC molecules. ... The SPECTRA of these molecules can be observed by Raman spectroscopy because the MOLECULAR vibration isRaman-allowed. DIOXYGEN is a special case as themolecule is paramagnetic so magnetic-dipole-allowed transitions can be observed in the INFRARED.
