it's FALSE I THINK so but not SURE

Payment for backorders or delayed products is generally the same as for pre-ordered items.  If you are using a credit card, the AMOUNT will be authorized but not charged until the item SHIPS.  If you are paying by debit card, your bank reserves the FUNDS and pays that amount to Barnes & Noble when we ship the item(s). If there is an extended period of time (a week or more) between the order date and the ship date, the initial bank authorization will fall off eventually.  Barnes & Noble SUBMITS for re-authorization from the bank before shipping, to ensure the funds are still available.  If funds are not available, the order will fall into a failed status, and eventually cancel if no action is taken. Please note: Barnes & Noble does not reimburse any bank, credit card, or debit card overdraft charges.

Natural polymers OCCUR in nature and can be extracted. They are OFTEN water-based. Examples of naturally OCCURRING polymers are SILK, wool, DNA, cellulose and proteins.

these CHANGES takes place in the physical characterestics LIKE density, area etc...but the volume of all the PHASES REMAINS constant for example SOLID to liquid

tion:567+868№457√π78 will be the CORRECT EQUATION

is 12 and 10.Explanation: S + O2 ⇒ SO2S + O2 ⇒ SO3let mass of so2 ⇒ xand mass of so3⇒ 22-x From 1ST equation ,1 MOL of so2 is formed by 1 mol of SULPHER.from 2nd equation,1 mol of so3 is formed by 1 mol of sulpher.mole of so2  + mole of so3  ⇒ mole of sulpher +   = X = 12∴ mass of so2 is  12 g and mass of so3 is 10 g

solid particles have some amount of kinetic energy which increases with RISE in heat.it ALLOWS the particles to MOVE faster.therefore, higher the temp of LIQUID faster the solid will dissolve

I don't UNDERSTAND. so PLEASE LET me KNOW

The MATTER are of three types-1.solid-It has it's fixed shape and volume.It cannot be compressed .2.liquid-It donot have it's definate shape it TAKES the shape of it's CONTAINER in which it has kept.3.gases-it can compress easily.it donot have it's definate shape.

e ✌✌✌Answer:Acid is ALWAYS added to water and not water to the acid .Because if we will add water in acid then there exothermic REACTION will take place and ALSO there will be chance of explosion .So it is safe ,to add small amount of acid to water the HEAT evolved is easily absorbed by the water .Hope it HELPS you . :---)

separation of H+ ION from HCL molecules cannot occur in absence of WATER and hence HCl does not show ACIDIC property in gaseous state...

Since in this system, there is a SPHERE at the CENTER of each face of the UNIT cell hence this structure is also KNOWN as face-centred cubic (fcc) structure. It may be noted that in CCP (or fcc) structures each sphere is surrounded by 12 spheres hence the coordination number of each sphere is 12.

6.02E23 this is your QUESTIONS BEAUTIFUL and NICE ANSWER

×1023 atoms of OXYGEN Explanation:The question is incomplete. We have to find out the no. of atoms of oxygen in 10 G of water.First we need to find out moles of water Moles = mass / molar massmole of water = 10 /(1.008*2+16) = 10 /18 = 0.56Now, as we know 1 mole contains 6.022 × 10 ^23 atoms or MOLECULES  Now from the formula we know, 2 mole of water contains 1 mole of oxygen then moles of oxygen in 10G of water = 0.28 atoms of oxygen  in 10g of water  = 0.28 * 6.022 × 10 ^23  =  1.6856 ×1023 atoms of oxygen

aExplanation:allotropes of CARBON are graphite and diamond.they are NANO TUBES, fullerene and nano buds.it only forms COVALENT bond as it shares its bonds only with the valence electrons. it does not have the ABILITY to lose all its bonds at a time

ement reaction is a chemical change, in which a more active element displaces a LESS reactivate element from its salt solution. ... Double displacement reaction is a chemical change in which two compounds exchange their RADICALS with each other to form new compounds. EXAMPLE - Mg + H2So4 ---> MgSo4 + H2.

We KNOW that, % of any element in a compound=mass of element--------------------------×100mass of compound% of BORON  = 0.096/0.24 X 100 = 40%% of OXYGEN = 0.144/0.24 X 100 = 60%

very very DIFFICULT so I cannot this GIVE ANSWER in SORRY this is a difficult QUESTION

b. CH and C6H6Explanation:Empirical Formula - A formula that gives the simplest whole-number ratio of atoms in a COMPOUND. START with the number of GRAMS of each element, given in the problem. the MASS of each element = the percent given. ... Divide each mole value by the smallest number of moles calculated.HOPE IT HELPS YOU....PLS MARK ME AS THE BRAINLIEST....

Explanation:Swedish chemist ARRHENIUS defined an acid as a SUBSTANCE that IONIZES in water to give HYDROGEN ions, and a base as a substance that ionizes in water to give HYDROXIDE ions. ... ACIDIC solutions are formed when an acid transfers a proton to water.

Damp weather RUSTS iron. EXPLANATION:PLEASE SELECT MY ANSWER AS THE BRAINLIEST ANSWER.

:Formula of the COMPOUND is Step-by-step explanation :Given that,ELEMENT N forms ccp arrangement.Atoms of element M occupy 1/3 of tetrahedral voids.Given that N forms ccp arrangement. Hence, it will have 4 atoms in a unit CELL.∴ Number of N atoms in unit cell = 4.Also, for each atom, there are two tetrahedral voids so that there are 8 tetrahedral voids PER unit cell.Then, according to the given data, No. of M atoms = ∴ Formula of the compound :-

3x+3(-2+1)=0 so x=3 is the OXIDATION no.of K

Polyester FABRICS and fibers are extremely strong. Polyester is very durable: RESISTANT to most chemicals, stretching and SHRINKING, wrinkle resistant, mildew and abrasion resistant.
