A solution may exist in any phase so your answer is D. any of the above
hope this helps :)
She will use the periodic table of elements to not only find out the chemical symbols of the elements written within the name, but also to check whether or not the elements are metals and or nonmetals, from this determine the ionic charges if needed for metals, and for metals that have more than one ionic charge, use a Roman numeral to represent the ionic charge that she would be using in writing the chemical formula of the compound.
Answer:
C- Using a 0.35 g sample of Li(s) cut into smaller pieces will increase the rate of reaction
C- Equal quantities of gas will be produced with potassium K, used instead of Lithium, Li.
Explanation:
<u>First part</u>
When a metal is present in small pieces, the rate of the chemical reaction increases. This is due to small pieces provide more surface area for reaction than huge chunks of Li.
moles of reactant decreases product formation rate also decreases and temperature decreases rate also decreases so remaining option are wrong
<u>Second part
</u>
2Li + 2H2O --------------> 2LiOH + H2
2K + 2H2O ---------------> 2KOH + H2
Hence, both gives same quantity of gas
