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

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)₂  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

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?
