Answer:
dinitrogen pentoxide
Explanation:
Based on the research, dinitrogen pentoxide is a chemical compound containing only nitrogen and oxygen which is both nonmetal. When two nonmetals or two negatively charged atoms try to form bonds, they always form covalent bonds. Hence, Dinitrogen Pentoxide is not ionic - it is covalent.
<span>The answer to this question would be: B. a solid that forms when two liquids are mixed
Precipitation is creating a solid substance from the solution. The product is called precipitate and the solution would be called supernate. Precipitation could happen because of gravity pulling up the molecule or because the molecule is saturated.</span>
Hey there!
The answer would be A - Combustion.
Answer:
Ba has the largest atom size
The theoretical molar yield of lead (II) chloride will be 9 moles.
<h3>Stoichiometric calculation</h3>
First, we need to look at the equation of the reaction:
![Pb^{2+} + 2Cl^- --- > PbCl_2](https://tex.z-dn.net/?f=Pb%5E%7B2%2B%7D%20%2B%202Cl%5E-%20---%20%3E%20PbCl_2)
From the equation, the 1 mole of Pb2+ ion requires 2 moles of Cl- ion in order to produce 1 mole of lead (II) chloride.
Thus, with 18 moles Cl- ions, 9 moles of Pb2+ would be needed, instead of 12 moles. Pb2+ is simply in excess while Cl- can be said to be limiting.
Therefore, Cl- will determine how much of lead (II) chloride that will be produced. The ratio is 2 moles of Cl- to 1 mole of lead (II) chloride.
With 18 moles Cl-, 9 moles of lead (II) chloride will, thus, be produced.
