A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 × 104 kPa and 4.34 × 103 kPa , respectively.What is t
Alchen [17]

Answer:

20.44\times 10^3 kPa is the total pressure of the tank.

Explanation:

Partial pressures of nitrogen = p_{N_2}=1.61\times 10^4 kPa

Partial pressure of oxygen =  p_{O_2}=4.34\times 10^3 kPa

Total pressure of gases in the tank = P

Applying Dalton's law of partial pressures :

P=p_{N_2}+p_{O_2}=1.61\times 10^4 kPa+4.34\times 10^3 kPa

P=20.44\times 10^3 kPa

20.44\times 10^3 kPa is the total pressure of the tank.

Identify the element whose highest energy electron would have the following four quantum numbers?
ad-work [718]

C. 6, 1, 0, -1/2

Explanation:

The four quantum numbers are:

  • Principal quantum number (n): this represents the energy level in which an orbital is located.
  • Azimuthal quantum number gives the shape of the orbitals in subshells accommodating the electrons.
  • Magnetic quantum number gives the number of spatial orientations or degeneracy of the orbitals in the subshells.
  • Spin quantum number describes the spinning of an electron in either clockwise or anticlockwise directions.

To know the electron with the highest energy, we use the principal quantum number values.

n values takes whole numbers i.e n = 1,2,3,4,5,6,7.............

The higher the value, the higher the energy level.

From the given quantum numbers, C has the highest energy levels.

Why is current more dangerous than voltage?
Serga [27]
The higher the current, the more likely it is lethal. Since current is proportional to voltage when resistance is fixed (ohm's law), high voltage is an indirect risk for producing higher currents.

sing any data you can find in the ALEKS Data resource, calculate the equilibrium constant K at 25.0°C for the following reaction
prisoha [69]

Answer:

2.76 × 10⁻¹¹  

Explanation:

I don’t have access to the ALEKS Data resource, so I used a different source. The number may be different from yours.

1. Calculate the free energy of formation of CCl₄

                         C(s)+ 2Cl₂(g)→ CCl₄(g)

ΔG°/ mol·L⁻¹:       0         0         -65.3

ΔᵣG° = ΔG°f(products) - ΔG°f(reactants) = -65.3 kJ·mol⁻¹

2. Calculate K

\text{The relationship between $\Delta G^{\circ}$ and K  is}\\\Delta G^{\circ} = -RT \ln K

T = (25.0 + 273.15) K = 298.15 K

\begin{array}{rcl}-65 300 & = & -8.314 \times 298.15 \ln K \\65300& = & 2479 \ln K\\26.34 & = & \ln K\\K& = & e^{26.34}\\&= & \mathbf{2.76 \times 10}^{\mathbf{11}}\\\end{array}
