Answer:
Hi, the question is incomplete. However, the question is about the calculation of volume of a product when the volume of one of the reactants is provided.
9.587 cm^3
Explanation:
The balanced equation for the chemical reaction is shown below:
⇒
In the chemical reaction above, 2 moles of water produced 4 moles of hydrogen fluoride. If 4.8 cm^3 of water were consumed, we can calculated the volume of hydrogen fluoride that would be produced as follow:
Using STP, 1 mole of gas has a volume of 22.4 L
Thus, 4.8 cm^3 = 0.0048 L is equivalent to 2.14*10^-4
since 2 moles of water produced 4 moles of hydrogen fluoride, therefore, 2.14*10^-4 would produced 2*2.14*10^-4 = 4.28*10^-4 moles
we can convert the moles to L by multiplying with 22.4
volume of hydrogen fluoride = 4.28*10^-4 * 22.4 = 0.009587 L = 9.587 cm^3

A is the correct answer
groups are the vertical columns on the table. if you look at it, you can see that the atomic number and atomic mass increases as you go down.
At constant temperature, if the volume of the gas decreased to the given value, the pressure increases to 2.16atm.
<h3>What is Boyle's law?</h3>
Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.
Given the data in the question question;
- Initial volume of the gas V₁ = 682mL = 0.682L
- Initial pressure of the gas P₁ = 1.33atm
- Final volume of the gas V₂ = 0.419L
- Final pressure of the gas P₂ = ?
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = ( 1.33atm × 0.682L) / 0.419L
P₂ = 0.90706Latm / 0.419L
P₂ = 2.16atm
Therefore, at constant temperature, if the volume of the gas decreased to the given value, the pressure increases to 2.16atm.

#SPJ1
Electron domain geometry takes into account the bonds and the free electrons around the atom to predict the geometry.
A tigonal planar geometry means that all the electron domains are in the plane and that they are as far away as they can. That means that there are three electron domains in the plane separated at 120 ° each other.
sp2 means that there are three hybrid electron domains, and the geometrh that leads to the minimal repulsion force is they placed at 120°, which exactly the trigonal planar geometry described up.
Then the answer is sp2
You can check in your book, that sp corresponds to two domains, located linearly, at 180°; and sp3 is four domains with the form of tetrahedral with 109.5° angles.
