o.O how?

if geeta's 62, then next year she wud be 63 and sunita - 33.

according to the question, next yr, geeta wud be 3 times sunita's age 11 years bak.

63 is not equal to 3*(33-11)

no. of moles of N2 = 7/28 = 1/4

no. of moles of CO2 = 11/44 = 1/4

total no. of moles = 1/2

PV =  nRT

1(V) = 1/2 * 0.0821 * 290 = 11.9 L

density = mass/volume = 18/11.9 = 1.512 gm/L

umm.. is the answer 1.512 gm/litre?

or electron deficient species like BF3

electrophiles r electron seeking species. they accept electrons, so they r usually positively or partially positive charged.

geeta's 59, sunita's 30 :D

err, since BF3 is a Lewis acid and NH3 is a Lewis base, NH3 donates its lone pair to BH3 and forms a dipolar bond.

NH3 gets a positive formal charge and BH3 gets a negative formal charge. an "adduct" is formed.

1. 3BaCl2 + 2Na2PO4 ---> Ba3(PO4)2 + 6NaCl

1 mole      0.4 mole

here, Na2PO4 is the limiting reagent. So,

3BaCl2 + 2Na2PO4 ---> Ba3(PO4)2 + 6NaCl

0.6 mole  0.4 mole          0.2 mole

therefore, no. of moles of Ba3(PO4) is 0.2

2. 3MnO2 ----> Mn3O4 + O2

No. of Moles of MnO2 = 10/87

=> no. of moles on Mn3O4 = 10/261

Weight  = molar mass * no. of moles = 229 *10/261 = 8.77g

3.  No. of moles of Phosphorus = 3.1/31 = 0.1

in Ca2(PO4)2, for 2 moles of P, there are 3 moles of Ca.

thus, for 0.1 moles of P, there is (0.1*3/2) = 0.15 moles of Ca.

therefore, Weight of Ca = no. of moles * atomic wt = 0.15 * 60 = 6g

at a basic lvl, u can figure out heights of towers and distances!

wat are fractals? if it is self-similarity, is the eiffel tower built on the concept of fractals?

Also, can the Prisoner's Dilemma be expressed as a dynamical fractal? if yes, how?
