Answer : The option (C) is not an oxidation-reduction reaction.

Explanation :

A : $XeF_6(s)\righatrrow XeF_4(s)+F_2(g)$

This is an oxidation-reduction reaction. In this reaction, the oxidation state of 'Xe' changes from (+6) to (+4) and the oxidation state of 'F ' changes from (-1) to (0). That means 'Xe' shows reduction and 'F' shows oxidation in the reaction.

B : $2Cs(s)+I_2(g)\righatrrow 2Csl(s)$

This is an oxidation-reduction reaction. In this reaction, the oxidation state of 'Cs' changes from (0) to (+1) and the oxidation state of 'I' changes from (0) to (-1). That means 'I' shows reduction and 'Cs' shows oxidation in the reaction.

D : $Zn(s)+2AgNo_3(aq)\rightarrow Zn(NO_3)_2(aq)+Ag(s)$

This is an oxidation-reduction reaction. In this reaction, the oxidation state of 'Zn' changes from (0) to (+2) and the oxidation state of 'Ag' changes from (+1) to (0). That means 'Ag' shows reduction and 'Zn' shows oxidation in the reaction.

C : $2H_2SO_4(aq)+2Ba(OH)_2(aq)\rightarrow 2BaSO_4(s)+4H_2O(I)$

This is not an oxidation-reduction reaction. In this reaction, the oxidation states are not changes.

Hence, the option (C) is not an oxidation-reduction reaction.

An oxidation-reduction reaction happens when hydrogen, oxygen or halogen atoms are transferred, so in this case, your answer would be B.

Which of the following correctly represents the transmutation in which a curium-242 nucleus is bombarded with an alpha particle

Alekssandra [29.7K]

<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

Transmutation is defined as the process in which one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.

The chemical equation for the reaction of curium-242 nucleus with alpha particle (helium nucleus) follows:

$_{96}^{242}\textrm{Cm}+_4^2\textrm{He}\rightarrow _{98}^{245}\textrm{Cf}+_0^1\textrm{n}$

The product formed in the nuclear reaction are californium-245 nucleus and a neutron particle.

Cobalt-60 is produced by neutron activation. in this process, one neutron is absorbed by the nucleus of the parent isotope. what

kkurt [141]

The parent isotope is cobalt-59 (see the picture below).

The mass number is 59 and atomic number is 27 of the parent isotope.

Neutron activation is the process in which atomic nucleus capture free neutron or neutrons.

Cobalt-60 is produced in nuclear reactors in process of neutron activation from parent isotope cobalt-59 (see the picture below).

Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.

Cobalt-59 and cobalt-60 are the isotopes of chemical element cobalt.

Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).
