Answer is: this is chemical <span>type of CBRNE exposure.
</span>CBRNE is an acronym for Chemical, Biological, Radiological, Nuclear and high yield Explosives (usually used for weapons of mass destruction).
Chemical weapons can be: nerve agents, blister agents, choking agents and blood agents.
Answer:
I3-(aq)
Explanation:
To measure the rate of this reaction we must measure the rate of concentration change of one of the reactants or products. This reaction may also be referred to as the iodine clock reaction. It yields the triodide ion which forms a blue complex with starch which enhances the determination of iodine even though iodine is coloured also.
Since the reaction is monitored by spectrophotometry, the concentration of the triodide ion can be monitored by spectrohotometric detection of the concentration of triodide ion present in the system. Hence we can use the determination of the amount of triodide ion by spectrophotometry to understudy this reaction.
Answer:
About 30.17 years
Explanation:
About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m . The remainder directly populates the ground state of barium-137, which is stable.
In general oxidation is defined as gain of oxygen or loss of electron or hydrogen by an atom. Reduction is defined as gain of electron or hydrogen or loss of oxygen by an atom.
In a balanced redox reaction we have two half reactions
a) reduction half reaction : the oxidation number of element decreases
b) oxidation half reaction : the oxidation number of element increases
The element undergoing reduction is Pd.
the oxidation number of Pd decreases from +2 to 0
Thus the reduction half reaction will be
The Pd (II) ion will take two electrons and will give Pd (0)
Answer is
The right answer is indeed letter c
