It's an oxidation/reduction reaction because there is a change in charge of the reactants.
Let's say Un=aqn and Sn=a+aq+aq2+aq3+aq4+aq5+...+aqn Sn = a (1+q+q2+q3+q4+q5+...+qn) A=(Sn/a) - q (Sn/a) = (1+q+q2+q3+q4+q5+...+qn) - q(1+q+q2+q3+q4+q5+...+qn) A=1+q+q2+q3+q4+q5+...+qn-q-q2-q3-....-qn-qn+1=1-qn+1 So A = 1-qn+1 = Sn/a (1-q) So Sn = a (1-qn+1)/(1-q)
The SN of 14.05 billion is: 14,050,000,000
i got the same question for homework in functions. tn=a+(n-1)d -50=-1+(n-1)-1 -50=-1-1n+1 -50=-1n therefore n=50 plug that into your sum equation...for convenience i used Sn=50/2 (-1-50) Sn=25 (-51) Sn= -1275 hope this helps!
make an A.P i.e:- 2,4,6,8..................200 therefore a=2 d=2 an=200 a+(n-1)d=200 2+(n-1)(2)=200 (n-1)(2)=198 N=100 Sn=100/2+[2+200] sn=50[202] sn=10100 . . . . . . . therefore sum of first even natural numbers is 10100
Sn = 3n2 + 2n - 8
The SN reaction is a substitution reaction. An example of the SN reaction is Br. H3CH2C.
-2
0.36 moles of SnF2
jg
9,846 g of tin (Sn)
Do not undergo SN1 reactions.
fusion
It is for Substitution Nucleophilic reaction in organic molecules.
No because zinc is more reactive than tin so it dilutes it
Tin, with chemical symbol Sn, is a main group metal.
SN 1572 or Tycho's Supernova was a supernova type Ia, in the constellation Cassiopeia
The reaction is:Sn + 2 HCl = SnCl2 + H2
