Answer:D

Explanation:

Use the vertex form, y=a(x−h)2+ky=a(x-h)2+k, to determine the values of aa, hh, and kk.a=14a=14h=6h=6k=1k=1Find the vertex (h,k)(h,k).(6,1)(6,1)Find pp, the distance from the vertex to the focus.
Find the distance from the vertex to a focus of the parabola by using the following formula.14a14aSubstitute the value of aa into the formula.14⋅1414⋅14Simplify.
Combine 4 and 1/4 .1 /4/4
Simplify by dividing numbers
Divide 4 by 44.1/1Divide 1 by 1/1.
Y=0
The Answer is D

Remember to balance the equations first

Semenov [28]

mol CO₂ = 9.6

mol N₂ = 4.8

mol O₂ = 0.8

mol H₂O = 8

<h3>Further explanation</h3>

Reaction

4C₃H₅O₉N₃ → 12CO₂ + 6N₂ + O₂ + 10H₂O

mol CO₂

$\tt \dfrac{12}{4}\times 3.2=9.6$

mol N₂

$\tt \dfrac{6}{4}\times 3.2=4.8$

mol O₂

$\tt \dfrac{1}{4}\times 3.2=0.8$

mol H₂O

$\tt \dfrac{10}{4}\times 3.2=8$

Match each set of quantum numbers to the correct subshell description by typing in the correct number.

ivann1987 [24]

The location of the valence electron or the outermost electron is expressed in quantum numbers. There are five quantum numbers: prinicipal (n), angular momentum (l), magnetic (ms) and magnetic spin (ms) quantum numbers. This is based on Bohr's atomic model where electrons orbit around the nucleus. These electrons are in the orbitals with specific energy levels. Starting from energy level 1 that is closest to the nucleus, the energy level decreases to 2, 3, 4, 5, 6, and 7. These energy level numbers represent the principal quantum number. Within each orbital also contains subshell. From increasing to decreasing order, these subshells are the s, p, d and f subshells. These subshells represent the angular momentum quantum numer. Specifically, s=0, p=1, d=2 and f=3. Therefore, if the electron is in the orbital 5p, the quantum number would be: 5, 1. Applying these, the correct pairing would be:

2p: n=2. l=1

Explain why doesn’t the total pressure increase when more gas is added to the chamber?

german

Pressure is inversely proportional to volume. Therefore, the effect of pressure change is opposite to the effect of volume change. So when more gas is added to the chamber the total pressure of the chamber doesn't increase.

<h3>What are the different relations between pressure and volume?</h3>

As the volume changes, the concentrations and partial pressures of both reactants and products change.
As the volume decreases, the reaction shifts to the reaction side with fewer gas particles.
As the volume increases, the reaction shifts to the side of the reaction containing more gas particles.
As the pressure increases, the equilibrium shifts towards reactions with fewer moles of gas.
As the pressure decreases, the equilibrium shifts to the side of the reaction with higher moles of gas.
Moreover, the pressure change in the system due to the addition of the inert gas is not limited to this.
