You need 0.111 g of NH₃ to provide the same number of molecules as
in 0.95 g of SF₆.
<em>Step 1</em>. Convert grams of SF₆ to moles of SF₆
Moles of SF₆ = 0.95 g SF₆ × (1 mol SF₆/146.06 g SF₆) = 0.006 50 mol SF₆
Now, we can use the knowledge that <em>1 mol of anything has the same number of molecules</em> (Avogadro’s number) <em>as 1 mol of anything else</em>
.
Thus, 0.006 50 mol NH₃ has the same number of molecules
as 0.006 50 mol SF₆.
<em>Step 2</em>. Convert moles of NH₃ to grams of NH₃.
Mass of NH₃ = 0.006 50 mol NH₃ × (17.03 g NH₃/1 mol NH₃) = 0.111 g NH₃
The chemical reaction known as fluorescence.
Here is the correct question.
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons.
NF3
SBr2
CCl4
Answer:
Explanation:
The objective here is to draw the molecule three molecules by placing atoms on the grids and connecting them with their respective bonds, therefore including all the lone pairs of electrons.
See the attachment below for the diagrams.
The first compound is know as Nitrogentrifluoride. A non-flammable greenhouse gas. It is majorly used for he production of semi conductors. It has a trigonal planar structure.
SBr2: Sulfur dibromide is a yellowish liquid toxic gas. It results as a reaction between SCl_2 and HBr. Its has a Bent Structure.
CCl_4 : carbon tetrachloride has the presence of a colourless liquid with a sweet smell. Carbon tetrachloride is used for different domestic uses such as: cleaning surfaces, fumigating, cleaning metals etc. It has a tetrahedral structure.
