What is the total ionic equation for the following reaction?

schepotkina [342]

Answer: Option (d) is the correct answer.

Explanation:

An equation in which electrolytes are represented in the form of ions is known as an ionic equation.

Strong electrolytes easily dissociate into their corresponding ions. Hence, they form ionic equation.

$H_{2}CrO_{4}$ is a strong acid and $Ba(OH)_{2}$ is a strong bases, therefore, both of them will dissociate into ions.

Thus, total ionic equation will be as follows.

$2H^{+} + CrO_{4}^{-} + Ba^{2+} + 2OH^{-} \rightarrow Ba^{2+} + CrO_{4}^{-} + 2H_{2}O$

very cold temperatures

Explanation:

A superconductor performs best at very cold temperatures.

A superconductor is a perfect conductor that is able to allow the passage of electricity and heat without resistance.

In superconductors, under certain conditions, resistance ceases to exist.
Examples are aluminium, niobium e.t.c
A conductor allows heat and current to pass through but with little resistance.
