A sample of neon gas in a bulb is at 149.05 °C and 349.84 kPa. If the pressure drops
KonstantinChe [14]

The new temperature (in °C) of the gas, given the data is –148.20 °C

<h3>Data obtained from the question </h3>
  • Initial temperature (T₁) = 149.05 °C = 149.05 + 273 = 422.05 K
  • Initial pressure (P₁) = 349.84 KPa
  • Volume = constant
  • New pressure (P₂) = 103.45 KPa
  • New temperature (T₂) =?

<h3>How to determine the new temperature </h3>

The new temperature of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

Since the volume is constant, we have:

P₁ / T₁ = P₂ / T₂

349.84 / 422.05 = 103.45 / T₂

Cross multiply

349.84 × T₂ = 103.45 × 422.05

Divide both side by 349.84

T₂ = (103.45 × 422.05) / 349.84

T₂ = 124.80 K

Subtract 273 from 124.80 K to express in degree celsius

T₂ = 124.80 – 273

T₂ = –148.20 °C

Does the iconic compound NaCl have the same particles as the individual elements of sodium and chlorine gas
valentina_108 [34]

Answer:It is not the same

Explanation: the normal sodium atom has an atomic number of 11 while Chlorine has an atomic number of 17. For Nacl; the sodium has lose an electron because it want to attain it octet configuration while chlorine accept the electron release to make it attain its octet configuration. At this point the elements are electrically stable.

Therefore, sodium become 10 and chlorine become 18

If 725 ml of N² gas is at 1 atm, what volume will it have at 1.4 atm?​
alexdok [17]

Answer:

518 mL

Explanation:

We can solve this using Boyle's Law Formula

P1V1 = P2V2

where p1 = initial pressure, p2 = final pressure, v1 = initial volume and v2 = final volume

here , the initial pressure is 1 atm and the initial volume is 725mL

we are given the final pressure 1.4 and we need to find the final volume

so we have p1v1 = p2v2

==> plug in p1 = 1 , v1 = 725 mL and p2 = 1.4

(1)(725) = (1.4)v2

==> multiply 1 and 725

725 = (1.4)(v2)

==> divide both sides by 1.4

v2 = 518

N2 would have a volume of 518mL at 1.4atm
