Answer:
1. Balanced
2. Unbalanced
3. Unbalanced
Explanation:
<em>Identify which of the following oxidation-reduction reactions are balanced and which are unbalanced in both mass and charge.
</em>
<em>
</em>
<em>1. Ag⁺(aq) + Li(s) → Ag(s) + Li⁺(aq)
</em>
This reaction is balanced in both mass and charge.
<em>2. Fe(s) + Na⁺(aq) → Fe²⁺(aq) + Na(s)
</em>
This reaction is balanced in mass but unbalanced in charge since the charge to the left is +1 and the charge to the right is 2+.
<em>3. K(s) + H₂O(l) → KOH(aq) + H₂(g)</em>
This reaction is balanced in charge but unbalanced in mass since there are 2 atoms of H to the left and 3 atoms of H to the right.
Answer:
Reaction of 1-butanol with bromobenzene
Explanation:
The reaction would yield ether as the major product is the reaction of the 1-butanol with bromobenzene. This is because the reaction does not have the large percentage of the undesired side product. In fact, the major product is about 85 % in composition, compared to the 15 % of the minor product. Hence, the reaction is efficient.
They all share the same atomic number (number of protons)
1.) A compound is a thing that is composed of two or more (separate) elements.
2.) A compound cannot be separated easily, while its properties differ from where it originates from. It also is formed from chemical reactions.
3.) A pure substance, also known as chemical substance, is a material with constant composition and consistant properties.
4.) If a substance is not a pure substance, then it is an impure substance.
Hope this helped. :)
