A 250.0-ml sample of ammonia, nh3 (g), exerts a pressure of 833 torr at 42.4 °c. what mass of ammonia is in the container
Lelu [443]
To solve this, let's assume ideal gas behavior.

PV=nRT
Let's solve for n. Convert units to SI units first.

Pressure = 833 torr(101325 Pa/760 torr) = 111,057.53 Pa
Volume = 250 mL(1 L/1000 mL)(1 m³/1000 L) = 2.5×10⁻⁴ m³
Temperature = 42.4 + 273 = 315.4 K

n = (8,314 J/mol·K)(315.4 K)/(111057.53 Pa)(2.5×10⁻⁴ m³)
n = 94.45 mol

The molar mass of ammonia is 17.031 g/mol.
Mass = 94.45*17.031 = <em>1,608.51 g ammonia</em>

What happens to wavelength as wave frequency increases?
KengaRu [80]

Answer:

As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

How does the electron configuration of elements within the same group compare? (A.) They all have their valence electrons in the
BaLLatris [955]

Answer:

( B) They all have their valence electrons in the same type of subshell.

Explanation:

With each period, a new shell is added to the atom.

Further, the groups are classified based on the type of subshell the last electron enters and number of valence electrons.

For all elements of same group, the last electron enters the same type of subshell.

Say, for group 1, last electron enters s orbital and they have 1 valence elctron.

for group 17, last electron enters p orbital and they have 7 valence electrons.

(A) and (D) are wrong because, energy level of the valence electrons is determined by the principle quantum number n and l and not by the type of subshell(only l) they enter.

(C) if the valence electron enters p orbital, then the elements will be placed in the p- block.
