Why are Sodium (Na) and Chlorine (CI) considered ions when reacting with<br> each other?
vlada-n [284]

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.

100 points - please help - chemistry
PIT_PIT [208]

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

In a voltaic cell, where does the oxidation take place?
faltersainse [42]
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

Hope this helps:-)

Which combination will produce a precipitate? Which combination will produce a precipitate? KOH (aq) and HNO3 (aq) AgC2H3O2 (aq)
crimeas [40]

Explanation:

A precipitate is defined as an insoluble substance that emerges upon mixing of two aqueous solutions.

For example, 2NaOH(aq) + Sr(NO_{3})_{2}(aq) \rightarrow Sr(OH)_{2}(s) + 2NaNO_{3}(aq)

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.

KOH(aq) + HNO_{3} \rightarrow KNO_{3}(aq) + H_{2}O(aq)

AgC_{2}H_{3}O_{2}(aq) + HC_{2}H_{3}O_{2}(aq) \rightarrow \text{No reaction}

Pb(NO_{3})_{2}(aq) + HCl(aq) \rightarrow PbCl_{2}(s) + 2HNO_{3}(aq)

Cu(NO)_{3}_{2}(aq) + CH_{3}COOK(aq) \rightarrow Cu(CH_{3}COO)_{2})(aq) + 2KNO_{3}(aq)

2NaOH(aq) + Sr(NO_{3})_{2}(aq) \rightarrow Sr(OH)_{2}(s) + 2NaNO_{3}(aq)

Hence, we can conclude that out of the given options, these two equations will produce a precipitate.

Pb(NO_{3})_{2}(aq) + HCl(aq) \rightarrow PbCl_{2}(s) + 2HNO_{3}(aq)

2NaOH(aq) + Sr(NO_{3})_{2}(aq) \rightarrow Sr(OH)_{2}(s) + 2NaNO_{3}(aq)
