The empirical formula is BH₃. Its B:H ratio is 1:3.
<em>Assume</em> that you have 100 g of the compound.
Then you have 78.14 g B and 21.86 g H.
Now, we must <em>convert these masses to moles</em> and <em>find their ratios</em>.
From here on, I like to summarize the calculations in a table.
<u>Element</u> <u>Mass/g</u> <u>Moles</u> <u> </u><u>Ratio </u> <u>Integers</u>
B 78.14 7.2285 1 1
H 21.86 21.686 3.0001 3
The empirical formula is BH₃.
When you squeeze a balloon you re putting all of the air to the top or the bottom of the balloon so at some point it will overflow of so much air that it will pop. It is kind of like when we hold our breath for to long, instead of popping, we pass out. Because we need air and so does the balloon. If the balloon was meant to be squeezed, it would've been all mushy so you can squeeze it and it would be like goo. So if you don't wanna pop your balloon, then don't squeeze it.
Mass = 35.0 g
density = 1.036 g/cm³
volume = ?
therefore:
D = m / V
1.036 = 35.0 / V
V = 35.0 / 1.036
V = 33.784 cm³
answer D
The electrostatic potential is the work done to remove the charge. The molecule showing the potential map shows that it is HI.
<h3>What is electronegativity?</h3>
Electronegativity is the elemental property to attract the electron toward the atom and is affected by atomic number and the atomic radius. The map shows that the molecule is made of two different atoms and has linear geometry.
Due to the linear geometry, the molecule cannot be Br₂ and SO₃ as they are nonpolar and nonlinear respectively. Similarly, BrF and ICl can be eliminated as they are interhalogen compounds. In the HI molecule, the hydrogen atom is a cation and the iodine atom is an anion that has high electronegativity differences.
Therefore, HI is the molecule depicted in the potential map.
