The bonds in salt compounds are called ionic because they both have an electrical charge—the chloride ion is negatively charged and the sodium ion is positively charged.
Answer:
Explanation:
1. Cu(NO3)2 + 2NaOH → Cu(OH)2 + 2NaNO3
2. FeSO4 + 2 NaOH = Fe(OH)2 + Na2SO4
3. Fe(NO3)3 + 3 NaOH = Fe(OH)3 + 3 NaNO3
For the second part of 3 since it tells us NaOH is excess we dont care about it. We use our balanced equation 3 to get the correct molar ratios to solve this.
1.5mol Fe(NO3)3 x 3mol NaNO3/1mol Fe(NO3)3 x 84.99gNaNO3/1molNaNO3
= 382.455g NaNO3
An electrode is strip of metal on which the reaction takes place<span>. In a </span>voltaic cell, theoxidation<span> and reduction of metals occurs at the electrodes. There are two electrodes in a </span>voltaic cell, one in each half-cell<span>. The cathode is where reduction </span>takes place<span>and </span>oxidation takes place<span> at the anode.
So, the answer is A. anode

Explanation:
A precipitate is defined as an insoluble substance that emerges upon mixing of two aqueous solutions.
For example, 
As precipitate is a solid and it is represented by (s). And, an aqueous solution is represented by (aq).
So, the products of the given reactants will be as follows.
Hence, we can conclude that out of the given options, these two equations will produce a precipitate.
