Answer : The correct option is, $H_2PO_4^-+H_2PO_4^-\rightarrow HPO_4^{2-}+H_3PO_4$

Explanation :

Disproportionation reaction : It is a chemical reaction in which a molecule is converted or transformed into two or more different products.

It is type of redox reaction where a species simultaneously oxidized and reduced and form different products.

From the given options, only one option shows the disproportionation reaction which is:

$H_2PO_4^-+H_2PO_4^-\rightarrow HPO_4^{2-}+H_3PO_4$

In this reaction, oxidation and reduction reaction takes palace simultaneously by the one species that is, H_2PO_4^- .

In this reaction, oxidation takes place when H_2PO_4^- lose electrons and form $HPO_4^{2-}$ and reduction takes place when gain electrons and form H_3PO_4 .

Hence, the correct option is, $H_2PO_4^-+H_2PO_4^-\rightarrow HPO_4^{2-}+H_3PO_4$

Answer from: Quest

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

Answer from: Quest

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
