Reduction is defined as chemical reaction in which addition of electrons takes place. During reduction reaction oxidation state of the an element decreases.
The standard reduction value on an element is determined with respect to the reduction potential of hydrogen.The standard reduction potential of hydrogen is 0.0 Volts
With negative standard reduction potential means that they have higher tendency to loose electrons.By loosing of electrons elements gets oxidize.
With positive standard reduction potential means that they have higher tendency to gain electrons.By gaining of electrons elements gets reduce.
Hence, from the given options the correct answer is option A.
<span> because gasoline changes volume as a function of temperature or because there are different grades of gasoline or because the values are given in different units of measure .</span>
<span> We are given with the rate constant of a first-order decomposition of n2o which is equal to 3.40 s-1. Half life of the radioactive material can be determined through the formula: t= ln2 /k where t is the half life of the material. t then upon substitution is equal to 0.2048 s. </span>
