610.864 Energy result in kilojoules:
Answer:
B
Explanation:
Solutions of substances that can conduct electricity are termed electrolytes. These solutions allow electricity to pass through them.
How strong a solution is to allow the passage of electricity is strongly dependent upon the availability of charge carriers within the solution matrix. In sharp contrast to the other solutions in the question, we can see that the presence of sodium and chloride ions in the matrix provides a boost for the solution to act properly as an electrolyte. Hence, it is a better solution than the rest of the options to serve as an electrical conductor
- The reaction in which we can't take back the product to reactant form .Or in simple words the reaction which is irreversible is called chemical reaction
Example:-
We cannot pull back the reaction to get wax back .
The element itself is Yttrium, which is a transition metal and not that reactive. Since it has 39 protons it will also have 39 electrons.
In order to answer this, you need to find the empirical data for the standard entropies. Please refer to this link: http://www.mrbigler.com/misc/energy-of-formation.PDF
For NO₂ gas, the entropy is 240 J/mol-K. For N₂O₄ gas, the entropy is 304.2 J/mol-K. Therefore, <em>the statement is false.</em>
