Mass is a coherent, typical large body of matter with no definite shape. Another way to describe matter is a very heavy or large object.Matter can also be described with length. This is how i know matter is a very large length or weight. (Hope this helped) :)
Answer:
Option 3.
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Explanation:
To know which option is correct, we must have an ideal of what is acid–base neutralization.
Neutralization is a reaction involving an acid and a base which produces salt and water only.
With the above information, we can easily detect the equation describing acid-base neutralization reaction by considering the products of each reaction to see the one that has water as part of the products.
From the question given above, only the 3rd equation gas water as part of the products i.e
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Hence, equation 3 is an acid-base neutralization reaction
The ionic equation will be:
<span>Mg2+(aq) + 2OH-(aq) + 2H+(aq) + 2NO3-(aq) → Mg2+(aq) + 2NO3-(aq) + 2H2O(l)
</span>And the net ionic:
<span>2OH-(aq) + 2H+(aq) → 2H2O(l)
</span>a Balanced equation would be:
<span>Mg(OH)2(aq) + 2HNO3(aq) → Mg(NO3)2 (aq) + 2H2O(l)
</span>Now thsi si so because of the standard equation which is base plus acid=Salt plus water. We need to have in mindo that Mg(OH)2 is sparingly soluble in water and is aqueous mos of the times
First find the moles of CO3.
<span>B, An Arrhenius acid donates H+ ions.</span>
