Answer:
Limitations of Lewis structures: resonance structures and violations of the octet rule (odd electron, hypovalent and hypervalent molecules). (1) Shapes of simple molecules with “central” atoms. (2) Configuration: the position of atoms in space about a central atom. The VSEPR theory of configuration.
1 mole ------------- 6.02 x 10²³ atoms
0.70 moles -------- ( atoms zinc )
atoms platinum = 0.70 x ( 6.02 x 10²³ ) / 1
<span> = </span>4.2 x 10²³ atoms zinc
<span>hope this helps!</span>
As the temperature of a gas increases, the average kinetic energy of the gas particles increases and the average speed of a gas particle increases.
According to the kinetic theory of gases, all gases are made of microscopic molecules that move in straight lines until they bump into another gas molecule or object. This transfer of energy causes molecules to move around faster and bump into each other more.
Kinetic energy is proportional to the speed of the molecules. As the speed of the colliding molecules increases, so does the total kinetic energy of all the gas molecules. It's pretty difficult to measure the speed of an individual gas molecule.
Instead, temperature can be used as a measure of the average kinetic energy of all the molecules in the gas. As the gas molecules gain energy and move faster, the temperature goes up. This is why Amy feels warmer!
To determine the average kinetic energy of gas molecules, we need to know the temperature of the gas, the universal gas constant (R), and Avogadro's number (NA).
