How to compare the melting point of two ionic bod or two covalent bond?
why does MgO has a higher boiling and melting point than NaCl?
Math ( Polynomial )
by using long division, divide x^4-6x^3+16x^2-25x+10with x^2-2x+k, then you will find: remainder=(-9+2k)x +10-8k+k^2 comparing with x + a, -9+2k=1,k=5 a=10-8k+k^2,a=-5 therefore k + a=5-5=0
Is it correct?
My way of solving...... Let k=m+1 2^(m+1)-2^m <1000 2^m <1000 m<=9 therefore k<=10 For distinct value of k and m, when k=1, m=0 when k=2, m=0,1 when k=3, m=0,1,2 . . . when k=10 2^k−2^m<1000 2^10-2^m<1000 m>=4 no of possible value of m is 5 total pos...
is this mean that e/z notation can definitely explain cis-trans isomerism but cis-trans not necessary can explain e/z notation ?
i have seen it but still dont understand.....
What is the difference between e/z notation and cis-trans isomerism?
is it 3?
sorry about that.... I thought 0 is neither even nor odd....
