No it is a not a DOUBLE REPLACEMENT REACTION it is a NEUTRALISATION reaction

When FERROUS Sulphate Crystals are STRONGLY heated, then DECOMPOSITION REACTION takes place.


When a substance decompose into constituent PARTICLES by the action of heat, PRESSURE, ETC., thw reaction is called decomposition reaction.

Egg SHELL is made of calcium CARBONATE. We know that when calcium carbonate reacts with NITRIC acid, it gives carbon DIOXIDE, calcium nitrate and WATER. Same reactionhappens when nitric acid is poured over egg shell.

Hey FRIEND!!!

_______________________________

Actually, We don't NEED all the 3 to distinguish,
1 is enough

We will mix Sol. of Litmus/ Litmus paper in Both Solutions,

Once we mix, ACID i.e. HCl, turns RED colour

Since, water is neutral, Colour will not change!

ANSWER:

EXPLANATION:

Since some ions are missing from their INTERSTITIAL position,hence DENSITY decreases.

Explanation:

On REACTION of dilute acid with metal, HYDROGEN GAS is liberated

Answer:

EXPLANATION:

Salt is FORMED due to a neutralisation reaction between ACID and base.

Sodium CHLORIDE (NaCl)

CALCIUM chloride (CaCl2)

PLEASE mark as BRAINLIEST ANSWER

the ACID BECOME DILLUTE acid

Normality is the number of hydrogen IONS in a base or acid.

Normality = molarity × number of hydrogen ions.

There is 1 hydrogen ion.

MOLAR CONCENTRATION = normality ÷ number of hydrogen ions

Molar concentration = 2/1 = 2

I) Anti-acids are MEDICINES containing bases such as aluminium hydroxide, Al(OH)3 and MAGNESIUM hydroxide, Mg(OH)2 to neutralise the excess acid in the stomach. (ii) Vinegar isused to cure wasp stings because vinegar can neutralise the stings. (i) Bee stings and ant BITES are acidic in nature.

Answer: No,

Explanation:Tartaric ACID does not evolve any carbon dioxide during BAKING ,its ROLE is to react with SODIUM carbonate (Na2Co3) formed when sodium hydrogen carbonate (NaHCo3)

Decomposes. If it is not done,Na2Co3 will IMPART bitter taste to the cake.

ACID GROUP or CARBOXYLIC group

Here is your ANSWER in this PICTURE

When we POUR some ACETONE on our PALM then it will vapourisey

W/v imply (mass of SOLUTE/ volm of soln) × 100.
So find mass of solute. then find MOLES of solute. then gram equivalents= no. of moles × n factor( for h2so4 n factor=2). then normality= gram EQ/ volm of WATER+ volm of h2so4

The freezing point is -0.272 degree Celsius is the freezing point.

Explanation:

• For finding the boiling point we will use the van’t Hoff factor which is

and for water are 0.512 and 1.86 K

• ‘i’ is given as 1 because it is a non-volatile SOLUTE.

• Therefore

• This gives us the value of m which is equal to 0.2929.

• Now when we add the volume of the water we get

• Therefore m' is equal to  which gives us a value of 0.1464.

• Therefore the temperature of freeing is which is which is equivalent to 0.272.

• Therefore to find the we need to apply the formula of

which gives us a value of -0.272 degree Celsius.

Ua ANSWER ^*^
Citrus fruits: all of 'em. It's strongest in lemons and limes, which are up to 8% citric acid by weight and can even be used to extract the chemical from; sour oranges can also be used, so we assume that the more sour the fruit the higher the citric acid content.
Berries and soft fruit: Almost all berries with the possible EXCEPTION of blueberries. Certainly found in: strawberry, raspberry, gooseberry, cranberry, redcurrant, blackcurrant. Redcurrants are one of the worst offenders - redcurrant juice can be used to replace lemon juice in jam recipes!
Exotic fruits: Pineapple, tamarind
Stone fruits: Cherries (apparently only a small amount)
Vegetables: Tomatoes, cayenne peppers (not the same as sweet peppers), Jerusalem artichoke, lettuce (!)
Wine - as a by-product of fermentation, and to improve clarity
Cheese - Citric acid is used in the manufacturing process to help clot the milk FASTER. It may be an integral part of making certain CHEESES, especially mass-produced mozzarella, but appears to be a by-product of industrialisation for most British cheeses: the traditional method of adding BACTERIAL culture to the milk and allowing it to act slowly does not use added citric acid as far as I know. I don't, however, know whether citric acid also appears naturally in cheese as a by-product of the bacterial reactions. Conclusion: traditional (read: expensive) cheeses are likely to be safer, but the jury's out overall.
Sourdough breads eg. rye bread - as a by-product of fermentation.

Carbon : Hydrogen mole ratio = 85.7/12:14.3

= 7:14 = 1:2

Empirical formula = CH2: empirical formula wt = 14

Given 1 LITRE at ntp WEIGHS 1.26 g

Therefore 22.4 litres will weigh 22.4 X 1.26 = 28 g

n = 28/14 = 2

Therefore formula of the hydrocarbon is C2H4 is ETHYLENE.

The simplest way to describe an ALLERGIC reaction is the way in which your immune system handles different proteins which are contained in various types of food. Your body can see these proteins as a potential threat which causes the immune system to release an array of chemicals which trigger an allergic reaction. The SEVERITY of any reaction will vary but in some circumstances it can prove fatal and therefore the issue of ALLERGIES is taken far more seriously today than it ever has been.There are various common foods which trigger allergic REACTIONS in children and adults. The more common foods which can trigger allergic reactions in children include:*.EGGS*.Milk*.Soya*.Wheat*.Peanuts

Explanation:

ughhhbbhhhhhhhhhhiuih bfithnv

It's INORGANIC ... because it don't CONTAIN CARBON as the BASIC ELEMENT. ...

Because at boiling POINT and sublimation point states are changed. ..
Means at boiling point liquid changes to gas
and at sublimation solid directly changes to gas
So after these temprature HEAT is absorbed to change the STATE therefore temperature remain same...

If RAYON is OBTAINED from wood pulp but it is CALLED synthetic fibre because it is also chemically TREATED

As down the group the orbitals increases thus shielding effect also increases so the nucleus of HALOGENS can't attract more electrons as we move down the group
So the REACTIVITY of HALOGEN acids DECREASES down the group
