Under what conditions do real gases behave most ideally.
katrin [286]

Answer:

Under high temperatures and low pressure, gases behave the most ideal.

Explanation:

Low pressure reduces the effect of the finite size of real particles by increasing the volume around each particle, and a high temperature gives enough kinetic energy to the particles to better overcome the attractions that exist between real particles. (Prevents sticking.)

In summary, real gases behave more like ideal gases when they are far away from a phase boundary, (condensation or freezing).

What are the differences between amorphous and crystalline solids? Give an example of each.
Eddi Din [679]

Answer: orderly arrangement of particles

Explanation:

In a crystaline solid, the particles that compose the solid are arranged or packed in an orderly manner to form a three dimensional crystal lattice with a defined structure. Sodium chloride is a crystaline solid.

In an amorphous solid, the particles that compose the solid aren't arranged in an orderly manner hence the solid tends to be brittle, e.g glass

Please help me I'm really confused on how to do this. Can someone break it down for me? (stoichiometry)
bazaltina [42]

Answer:

so with every stoichiometry problem with a mass it will make it so you can do the conversion factor with reactants or products.

if you dont understand unit conversions try to study how to set it up. anyways

a.) C12H22O11 has a mass of 342.01 Grams per mole

divide 1.202 G by 342.01 G to get 0.004 miles

b.) you're just taking the AMU of each element in the chemical multiply it by how many there is of it in the chemical, then divide it by the mass of a mole of the chemical.

c.) you take your answers of part b and multiply them by Avogadro's number
