Answer:
Explanation:
Observation. Observational skills are the starting point for critical thinking. People who are observant can quickly sense and identify a new problem.
Analysis. Once a problem has been identified, analysis skills become essential. ...
BF3 acts as a Lewis acid when it accepts the lone pair of electrons that NH3 donates.
Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.
<h3>What is Lewis dot structure?</h3>
A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.
Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

The mass of Fe(NO3)2 you have is 245 g * 0.805 = 197.23 g
<span>The molar mass of Fe(NO3)2 is 179.85 g/mole so you have 1.0966 moles </span>
<span>From the balanced equation, that is the number of moles of Fe you make since both Fe(NO3)2 and Fe have a 3 in front of them. </span>
<span>The mass of Fe is 1.0966 moles * 55.85 g/mole (atomic mass of iron) = 61.246 g. From the information you are given, your answer should be in 3 sig figs so 61.2 g </span>
<span>Moles of HCl = 8.2 L * 3.5 mole/L = 28.7 moles </span>
<span>From the balanced equation, you need 1/2 the moles of zinc as you have of HCl so you need 14.35 moles. </span>
<span>To get the mass of zinc, multiply moles of zinc by its atomic mass = 938.2 g. From the information given, your answer should be in 2 sig figs so I would report it as 9.4 * 10^2 g, that clearly shows 2 sig figs.</span>
