the STRUCTURE of HEXYNE

The humidity (amount of water vapour present in the AIR) is low on a dry day.Being a hot dry day, the temperature is high and the humidity is low. The RATE ofevaporation increases withi. increase in temperatureii. DECREASE in humidityTherefore, the rate of evaporation and hence the cooling EFFECT due to evaporation ishigh on a hot dry day. Thus, DESERT cooler cools better on a hot dry day.

H 3 - most acidicpH 7 - neutralpH 10 least ACIDIC (basic)THEREFORE 10, 7, 3

Peroxides are the compounds that CONTAIN two oxygen atom linked together by a single COVALENT bond.Uses of Peroxides are:-Hydrogen peroxide act as an antiseptic which is USED on the skin to prevent INFECTIONS of scrapes, minor cuts and burns. It can also be used as mouth rinse that HELP in removing mucus or to relieve minor mouth irritations.To bleach hairSpraying little amount of peroxide can help to keep the food fresh.Hope it helps you

CH_4(S) +2O_2(G)=CO_2(G)+2H2_O(AQ)EXPLANATION:S = SolidG = GasAq = AQUEOUS

Here is your ANSWEREXPLANATION:GRAHAM’s law of DIFFUSION - \dpi{100} r_{1}/r_{2}=\sqrt{M_{1}/M_{2}}  where r is rate of diffusion of gas , M is molar mass. -     As per graham's law of diffusion   \frac{r_{1}}{r_{2}}=\sqrt{\frac{M_{2}}{M_{1}}} given that \frac{r_{1}}{r_{2}}={\frac{1}{3}} M_{2}=4 \Rightarrow \frac{1}{3}=\sqrt{\frac{4}{M_{1}}} \Rightarrow \frac{1}{9}={\frac{4}{M_{1}}} \Rightarrow M_{1}=4\times 9 = 36

plastic is very harmful thing for NATURE and ENVIRONMENT it dosen't MIX with SOIL its examples are plastic bags plastic TOYS and so on

it is formed by REACTION of ACETIC ACID and sodium hydroxide

iend !☺> Here's your ANSWER : An electrolyte is basically a substance which conducts electricity or carries an electric CHARGE in its aqueous form ( ie when it is dissolved in water ).There are MANY common ELECTROLYTES such as NaCl.... etc__________________________Thank you ! ♠Doubts are most WELCOME :)

sir plz explain once again100gm of Sample of CACO3 reacts with98grmsе оf H3PO4 -calculatea) no of grams of CA 3 (PO4)2 that COULDBE producedb) the no of grams of EXCESS reagent thatwill remain unreacted

Explanation:No there is no CHANGE in mass when a SUBSTANCE CHANGES its STATE

Explanation:2Kclo3=2kcl+3o2¶

cannot displace ZINC from its salt solution. A HIGHER reactive metal can displace less reactive metal from its aqueous salt solution. Hence, COPPER being less reactive than zinc, cannot replace it from a zinc SULPHATE solution. Mark me Brainly

tion:A higher REACTIVE metal can displace less reactive metal from its AQUEOUS SALT solution. Hence, COPPER being less reactive than zinc, cannot replace it from a zinc sulphate solution. PLS MARK AS BRAINLIST...

latent heatExplanation:when u heat the kettle the water will heat at 105°c HENCE when kettle KEPT out, it condenced and CHANGES to water in between the STEAM MIX with all the air present

:Electrode POTENTIAL of copper wire = 0.31045 volt.Step-by-step EXPLANATION :Given that,Standard electrode potential of copper = 0.34 volt.The electrode reaction written as reduction reaction is as follows :-Now, APPLYING Nernst eqn. we get,PUTTING the values, we get,

hey I HOPE it may be true .......nd if yes then I FEEL happy for correct nd LIKE the ANSWER so that I can get the notification about my answer that I have DONE right....

of ice is less than that of water. THEREFORE ice FLOATS on water. please MARK as BRAINLIEST....and FOLLOW me...

I HOPE it MAY be TRUE......

Mass of AL=27gMass of O2=32gBalanced chemical equation:4 Al  +  3 O2   ---------->  2 Al2O3Mole ratio of Al :O2 = 4 : 3,which is 1 : 3/4Mass of O2 REQUIRED = 3/4 * 32g                                    =24g

due to presence of extra energy in STEAM in the form of latent heat that is due to CHANGE the state. Steam has grater energy then WATER at 100 deg C, this extra energy NAMES as latent heat. So steam CAUSE more heating in compare to water at this temp.

dy here is your answerBoiling is the process in which atmospheric PRESSURE becomes equal to VAPOUR pressure, while in case of evopration vapour pressure should be grater then atmospheric pressure. In boiling no need to change in STATE of substance, while in case of evopration it happens. Evopration requires more energy then boiling.Have FUN here .

80.0Explanation:Its GOOD to UNDERSTAND BROMINE

3+3H2SO4 GIVES AL2(SO4) +6H2O

tion : A METAL having LOWER standard reduction potential will act as anode and undergo corrosion when coupled to another metal having HIGHER standard reduction potential. Therefore, in the case of steel pipe CONNECTED to a copper. Steel will be the anode (due to the lowest reduction potential), where the copper has a higher reduction potential in about +0.34 V.
