IgorLugansk [536]

Answer:

A. maintain electrical neutrality in the half-cells via migration of ions

Explanation:

Salt bridge -

For an electrochemical reaction , involving an anode and a cathode , both the electrodes are connect via a salt bridge to complete the circuit for the reaction .

One of the very important use of a salt bridge is to maintain the electrical neutrality of the respective half cells , which is achieved by the movement of ions .

Hence , from the given options , the correct option is ( a ) .

Write the Iconic Bond to Metals

Nutka1998 [239]

<u>Answer:</u> The ionic compound formed is magnesium chloride having formula $MgCl_2$

<u>Explanation:</u>

Ionic compound is defined as the compound which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

Magnesium is the 12th element of the periodic table having electronic configuration of $1s^22s^22p^63s^2$

This element will loose 2 electrons to form $Mg^{2+}$ ion

Chlorine is the 17th element of the periodic table having electronic configuration of $1s^22s^22p^63s^23p^5$

This element will gain 1 electron to form $Cl^{-}$ ion

So, for every 1 atom of magnesium, 2 atoms of chlorine are required. Thus, the chemical formula becomes $MgCl_2$

Hence, the ionic compound formed is magnesium chloride having formula $MgCl_2$

A certain vinegar is 6.02% acetic acid (hc2h3o2, by mass. how many grams of acetic acid are contained in a 355 ml bottle of vine

Eddi Din [679]

First, determine the amount of vinegar in grams by multiplying the volume by the density. That is,
mass = (355 ml) x (1.01 g/mL) = 358.55 g
Then, multiply the calculated mass above by the decimal equivalent of the given percentage above.
amount of acetic acid = (358.55 g)(0.0602) = 21.58 g
