Answer:
The two-dimensional crystal is shown in the attached file.
Explanation:
The two-dimensional crystal that contains six formula units of sodium chloride in the solid state is shown in the attached file. In the two-dimensional crystal, there are ion pointing outward and there are others pointing inward. Each sodium ion in the crystal is surrounded by 6 chloride ions. Similarly, each chloride ion in the crystal is also surrounded by 6 sodium ions. Due to this arrangement, the number six (6) is commonly known as the the coordination number of sodium and chloride ions.
Answer:
The particles in a liquid move very quickly due to heat while it is boiling and gradually turns to gas
Answer:
A. Potential energy is stored energy
Explanation:
Answer:
The new volume of the balloon will be 6046.28 L
Explanation:
Initial pressure (P1) = 99 kpa
initial volume (V1) = 3000 L
Initial temperature = 39 C = 39 + 273 = 312 K
Final pressure (P2) = 45.5 kpa
Final temperature = 16 C = 16 +273 = 289K
Final volume = ????
To calculate the final volume using the general gas equation
P1 V1 / T1 = P2 V2 / T2
make V2 the subject of the formular
V2 = 99000 ×3000× 289 / 45500×312
V2 = 85833000 /14196
V2 = 6046.28 litres
Answer:
relationship between four fundamental physical properties of gases: pressure PP, volume VV, number of moles nn, and the absolute temperature TT. The ideal gas constant is denoted by RR and its exact value depends on the units chosen for the other parameters. Note that the temperature is always in Kelvins (i.e., we use the absolute temperature). The relation is:
PV=nRT
