e addition of two vectors is zero, we draw the first vector, and then the second has to GO back to the origin. So, it must be in the opposite direction (to REVERSE what the first vector did), and have the same magnitude or LENGTH (to get EXACTLY to the origin).

In mineral acids, such as hydrochloric acid, sulphuric acid, NITRIC acid, etc. hydrogen ion dissociates COMPLETELY and hence they are considered as strong acid. Since, in organic acids hydrogen IONS do not dissociate completely, so they are weak acid. ALKALIS are WATER soluble base, thus in alkali; complete dissociation of ...

Ate.......❤️Aqueous humor is a CLEAR liquid found between the CORNEA and the lens of eye. vitreous humor is a clear GELATINOUS mass found in the REAR part of the EYEBALL between the lens and retina.

tion:Bases change the colour of litmus from red to blue.They are bitter in taste.Bases lose their basicity when mixed with acids.Bases react with acids to form salt and water. This process is called NEUTRALISATION Reaction(Read).They can conduct electricity.Bases feel slippery or soapy.Some bases are great conductors of electricity.Bases like sodium hydroxide, POTASSIUM hydroxide, etc are used as electrolytes.Alkalis are bases that produce hydroxyl ions (OH-) when mixed with water.Strong alkalis are highly corrosive in nature WHEREAS other alkalis are mildly corrosive.The pH value of bases ranges from 8-14.Alkalis and ammonium salts produce ammonia.Hydrogen gas is evolved when metals react with a base.Bases are classified on the basis of strength, concentration and acidity.The different kinds of acids are strong base acid, WEAK base acid, concentrated base, DILUTE base, monoacidic base, diacidic base and triacidic base.

Activity : • Take the mixture in a distillation flask. Fit it with a thermometer. • Arrange the apparatus as SHOWN in figure. • Heat the mixture slowly KEEPING a close WATCH at the thermometer. • The acetone vapourizes, condenses in the condenser and can be collected from the condenser outlet • Water is LEFT behind in the distillation flask. Criterion : Two miscible LIQUIDS that boil without decomposition and have sufficient difference in their boiling points can be separated by this method.Explanation:Hope this helps uh☺☺

hola mateBASEThey are BITTER in tasteThey change COLOUR from red to blue in litmus paperThey feel soapyThey can CONDUCT electricityThey feel slipperyhope it HELPS you

they are ACIDIC acids have sour taste acids are corrosive in nature acids turn BLUE litmus solution to RED methyl YELLOW to orange

It's a good thing these GASES are there. Our atmosphere protects the Earth from the harsh rays of the sun and reduces temperature extremes, acting LIKE a duvet wrapped around the planet. ...

Hey BUDDY here's your ansit is ARRANGING of living being in groups and subgroups on the basis of their FUNDAMENTAL similarities and disimilarities.

Common or vernacular NAME is RELATIONAL name spacificto a LANGUAGE which is given to an ORGANISM by local PEOPLE.

Diversityis the occurrence of VARIOUS types of living being which differ from ONE another in EXTERNAL form and the appearance, internal , structure, nutrients, behaviour, habitat etc

(i) The base X is Sodium Hydroxide (NaOH)When NaOH is kept in OPEN, it absorbs mosture to form acquous NaOH which is sticky.When ELECTRICITY is passed through the  aqueous solution of Sodium Chloride, it decomposes to form Sodium Hydroxide. This is called the chlor-ALKALI process because the products that are formed are chlorine (hence chlor) and Sodium Hydroxide which is alkaline (hence alkali).The balanced chamical reaction is as follows:NaCl (aq) + 2H₂O (l) → 2NaOH (aq) + Cl₂ (g) + H₂ (g)When NaOH is treated with dilute Hydrochloric Acid (HCl), neutralisation reaction occurs. NaOH is a base while HCl is a acid. They react to form salt and water.NaOH + HCl → NaCl + H₂O(ii) If water is added to the CONCENTRATED acid, the heat generated may cause the mixture to splash out of the container and cause burns because dilution of concentrated acid is an exothermic process.On the other hand, when acid is added to water, the solution that FORMS is very dilute amount of heat released is very small which is not enough to vaporize it. Therefore, it is always safer to add acid to water, and not water to acid.

resistance of the bulb = 500 Ωpower of the bulb. = 80WExplanation: ELECTRIC bulb,  connected to a 200 V sourceCurrent Drawn = 0.4 ACurrent = VOLTAGE / Resistance=> Resistance = Voltage / Current=> Resistance = 200/(0.4)=> Resistance = 500 Ωresistance of the bulb = 500 ΩPower =,Voltage * Current=> POWER = 200 * 0.4=> Power = 80 Wpower of the bulb. = 80W

The water MOLECULES that are attached with a given SALT in a FIXED MOLECULAR ratio in the crystalline state are CALLED water of crystallisation.e.g.:1. CuSO4.5H2O2. Na2CO3.10H2O3. CaSO4.2H2OExplanation:

1/Req  = 1/R₁  +1/R₂  + 1/R₃ +.........................+ 1/RₙExplanation:Let say there are n RESISTORS Connected in ParallellR₁ , R₂ , R₃ ,...........................RₙAnd Volatge applied = Vas RESISTANCE are in parallel so voltage across Each Resistance = VCurren through each resistore respectivelyI₁ , I₂ , I₃ ................................ IₙTotal Current I = I₁ + I₂ + I₃ +................................+ Iₙ=> V/Req  = V/R₁  +V/R₂  + V/R₃ +.........................+ V/Rₙdividing by V both sides=> 1/Req  = 1/R₁  +1/R₂  + 1/R₃ +.........................+ 1/Rₙhence the reciprocal of equivalent resistance of the COMBINATION is equal to the SUM of the reciprocals of the individual RESISTANCES of the resistors.

potential difference is CONSIDERED as the CHANGE in VOLTAGE of Del V .it is MEASURED in terms of voltage.

Heating effect of electric current:(a)when current flows through the conductor ,the heat is generated in the condutor due to the conveesion of electrical energy into heat energy this effect is called heating effect of electric current.(B)joules law:The heat produced in a conductor is (1)directly PROPORTIONAL to the square of the current.(2)directly proportional to the resistance of the conductor .(3)directly proportional to the time TAKEN by the current to flow through it.An expression for the heat produced by epectric current is (c)argon gas is filled in bulbs to PROTECT the filament of the bulb from corrosion because argon is LEAST reactive.
