If zinc and iron are used to make a cell what half-reactions will occur for zn2 plus aq plus 2e- zn s e0 equals -0.76 v and for fe3 plus aq plus e- fe2 plus aq e0 equals 0.77 v?
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
How figure answer for Zn plus O2 equals ZnO?
If you want to balance the equation, then: 2Zn + O2 --> 2(ZnO)
Has fermat's last theorem been disproved?
Fermat's last theorem says xn + yn = zn where n is bigger than 2 has no solution.The theorem has NOT been disproved, in fact it was proved by Andrew Wiles.He worked with Richard Taylor and they used things known as elliptic curves. There are many great books that explain the proof, but a good amount of graduate level abstract algebra is required.
Properties of Chi-square distribution?
It is a continuous distribution. Its domain is the positive real numbers. It is a member of the exponential family of distributions. It is characterised by one parameter. It has additive properties in terms of the defining parameter. Finally, although this is a property of the standard normal distribution, not the chi-square, it explains the importance of the chi-square distribution in hypothesis testing: If Z1, Z2, ..., Zn are n independent standard Normal variables, then the sum of their squares has a chi-square distribution with n degrees of freedom.
Who is person who is solving Fermat?
Andrew Wiles solved/proved Fermats Last Theorem. The theorem states Xn + Yn = Zn , where n represents 3, 4, 5,......... there is no solution.
Zn plus HCl equals ZnCl plus H is not correct?
No. Zn + 2HCl = ZnCl2 + H2
What is Zn plus KCl equals?
This question belongs to Chemistry.
What are the reactants to Zn plus HCl equals Zn plus H2?
2Zn(s) + 2HCL (aq) --> 2ZnCl + H2 (g) The reactants are zinc (Zn) and hydrochloric acid (HCl).
What kind of reaction is Zn plus 2NaCl equals 2Na plus ZnCl2?
single replacment
What is the fermat last theorem?
That there are no whole number solutions to the equation: xn + yn = zn when n > 2. If n = 2 this is: x2 + y2 = z2 is known as Pythagoras' Theorem, and has many whole number solutions, eg 32 + 42 = 52, 52 + 122 = 132.
What is being produced when Zn plus CuCl2 equals Cu plus ZnCl2?
Cu and ZnCl2 are being produced.
What is the number that no value of can be greater than for the solutions to the equation in fermats last theorem?
Fermat's last theorem states that the equation xn + yn = zn has no integer solutions for x, y and z when the integer n is greater than 2. When n=2, we obtain the Pythagoras theorem.
How many moles of zn are consumed when 1.60 x 1024 molecules of hcl react completely in the following equation zn plus 2hcl equals zncl2 plus h2?
Zinc and hydrochloric acid
What is the chemical equation for zinc plus cupric sulfate equals zinc sulfate plus copper?
the chemical equation for zinc plus cupric sulfate equals zinc sulfate plus copper can be written in the form of reaction as follows .ZN +Cu SO 4 -> Zn SO 4 + Cu.they form a aqueous solutions.
If zinc and iron are used to make a cell what half-reactions will occur for zn2 plus aq plus 2e- zn s e0 equals -0.76 v and for fe3 plus aq plus e- fe2 plus aq e0 equals 0.77 v?
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
What is the standard reduction potential for the half reaction Zn2 plus plus 2e- equals Zn?
Zn2+ + 2e- <--> Zno -0.7618 V
