D
Explicación:
Utilizamos la relación de moles para calcular la presión parcial. El número total de moles es 0.2 + 0.2 + 0.1 = 0.5 moles
Ahora, sabemos que la fracción molar del gas argón es 0.2/0.5
La presión parcial se determina así. Para calcular esto, simplemente multiplicamos el número de moles por la presión total.
0.2/0.5 * 5 = 1.0/0.5 = 2.00atm

Answer :
The percentage ionic character (%IC) equals 10%, indicating the bond is mostly covalent with slight polarity.
Percent Ionic Character:
This reflects the fraction of ionic nature within a polar covalent bond. The formula for %IC (% ionic character) is:
Here, Xa is the electronegativity of atom A and Xb is that of atom B.
Given: The compound is TiAl₃.
Electronegativity of Ti = 2.0
Electronegativity of Al = 1.6 (as shown in the provided image)
Substitute these values into the formula:
The value of e⁻¹ equals 0.90.
Therefore, percent ionic character = (1 - 0.90) × 100
Percent Ionic Character = 10%
Because the % IC is only 10%, which is relatively low, the bond is classified as covalent with minimal polarity.
Response:
3:1
Explanation:
Stearic acid - C18H36O2
Fructose- C6H12O6
The energy content in food is largely proportional to the carbon content. This can be expressed as:
C18/C6 = 3 or 3:1
This illustrates why fats and oils serve as the primary energy source for the body rather than carbohydrates. This is because fats and oils contain significantly higher amounts of carbon compared to carbohydrates.
Assuming the edge length of the cube is m.
Since the cube's sides are all equal, you can find its volume using the formula:
volume of cube = m^3
Now, using the provided edge length:
volume = (4.33)^3 = 81.1827 cm^3
According to unit conversion standards, 1 cm^3 = 0.001 liters.
So:
volume of cube = 81.1827 cm^3 = 0.0811827 liters
-0° is the freezing temperature of ice or ice cream.
