Answer:

(a) $2.316x10^2$ or $231.6$

(b) $8.5x10^{-3}$

Explanation:

Hello,

In this case, we must remember that we round numbers if the next number is equal or greater than 5 and that left-sided zeros are not included in the final result, in such a way:

(a) $2.316x10^2$ or $231.6$

(b) $8.5x10^{-3}$

Best regards.

Explain, in terms of intermolecular forces, why ammonia has a higher boiling point than the other compounds in the ta

Kobotan [32]

Answer is: ammonia has a higher boiling point because it has stronger intermolecular forces.

Intermolecular forces are the forces between molecules. The stronger are intermolecular forces, the higher is boiling point of compound, because more energy is needed to break interaction between molecules.
There are several types of intermolecular forces: hydrogen bonding, ion-induced dipole forces, ion-dipole forces andvan der Waals forces.

A gas occupies the volume of 215ml at 15C and 86.4kPa?

kherson [118]

Answer:

About 0.1738 liters

Explanation:

Using the formula PV=nRT, where p represents pressure in atmospheres, v represents volume in liters, n represents the number of moles of ideal gas, R represents the ideal gas constant, and T represents the temperature in kelvin, you can solve this problem. But first, you need to convert to the proper units. 215ml=0.215L, 86.4kPa is about 0.8527 atmospheres, and 15C is 288K. Plugging this into the equation, you get:

$0.8527\cdot 0.215=n \cdot 0.0821 \cdot 288\\n\approx 7.754 \cdot 10^{-3}$

Now that you know the number of moles of gas, you can plug back into the equation with STP conditions:

$1V=7.754 \cdot 10^{-3} \cdot 0.0821 \cdot 273\\V\approx 0.1738L$

Hope this helps!
