Hey there!:

1) The additional stability that accompanies the formation of the network<span>Crystalline is measured as network enthalpy. 
</span>2) The reticular energy is the energy released when the solid Crystal isform from separate ions in the gaseous state. Always exothermic.<span>
3) </span>The enthalpy of the network depends directly on the size of the loads and conversely in the distance between the ions .


hope this helps!

What volume does 14 mol of gas occupy at STP? Round to the nearest hundredth.
Anna007 [38]

Answer:

The volume is 310 L

Explanation:

We use the ideal gas formula, with the constant R = 0.082 l atm / K mol. The STP conditions are 1 atm pressure and 273 K temperature. Solve for the formula, V (volume):

PV= nRT ---> V= (nRT)/P

V=( 14 mol x 0,082 l atm /K mol x 273 K)/ 1 atm

<em>V= 313,404 L</em>

Which of the following most likely happens when the volume of a gas increases? (4 points)
Xelga [282]

Answer:

Molecules in the gas move faster due to the fact they have more energy

Explanation:

If you put more heat the higher the volume will be. Less heat means less volume.

olchik [2.2K]

Answer:

299.14 K or 26°C

Explanation:

The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas.

The ideal gas law is often written as

PV = nRT

where P ,V and T are the pressure, volume and absolute temperature;

n is the number of moles of gas and  R is the ideal gas constant.

n=1.10 x 10^5 mol  

V= 2.70 x 10^6 L  

P= 1.00 atm= 101.325 kPa  

R= 8.314 kPa*L/ mol*K

when the formula is  rearranged, T=PV/ nR  

T = (101.325kPa * 2.70 x 10^6 L)/ (1.10 x 10^5 mol * 8.314 kPa*L/ mol*K)  

T = 299.1421917 K

or

T = 299.14 - 273.15 = 25.99 =  26°C
