As known, nitrogen could form 3 bonds based on octet rule, because it has 5 valence electrons. That means it needs 3
There are many differences between ideal gas and real gas; some of the main differences are as following:
- An ideal gas follows the formula PV=nRT but a real gas does not always follow this formula.
- There is no attraction between the molecules of an ideal gas. A real gas has significant particle attractions.
- The particles of an ideal gas lose no energy to its container. A real gas conducts and radiates heat, thereby losing energy.
- An ideal gas is infinitely compressible, a real gas will condense to a liquid at some pressure.
- Real gas particles have a volume and ideal gas particles do not.
- Real gas particles collide in-elastically (loses energy with collisions) and ideal gas particles collide elastically.
Answer:
AlN₃O₉
Explanation:
Assume that you have 100 g of the compound.
Then you have 12.7 g Al, 19.7 g N, and 67.6 g O.
1. Calculate the <em>moles</em> of each atom
Moles of Al = 12.7 × 1/26.98 = 0.4707 mol Al
Moles of N = 19.7 × 1/14.01 = 1.406 mol N
Moles of O = 67.6 × 1/16.00 = 4.225 mol O
2. Calculate the <em>molar ratios</em>.
Al: 0.4707/0.4707 = 1
N: 1.406/0.4707 = 2.987
O: 4.225/0.4707 = 8.976
3. Determine the <em>empirical formula</em>
Round off all numbers to the closest integer.
Al: 1
N: 3
O: 9
The empirical formula is AlN₃O₉.
Sucrose is not very soluble in ethanol; therefore, the particles of sucrose will be visible in the solution containing both sucrose and ethanol.
