Answer: The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.
If you look closely at each of the four diagrams you would be able to conclude that
<span>D)
Yes. In B and D. In both cases, there is a net force.
In B, there is a net force to the left; in D there is a net force upward.
In A and C, the forces are in equilibrium both in the horizontal and vertical direction.</span>
Given:
n = 0.0021 mol
M = 44 gram/mol
Required: m or the mass of the molecule
Solution:
M = m/n
Rearranging the expression,
m = M x n
m = 44 g/mol x 0.0021 mol
Evaluating the expression and cancelling units, we obtain,
m = 0.0924 grams
M is the molar mass. This value is very useful in chemistry calculations especially in calculating the amounts of reactants and products for a chemical reaction.
No matter how big or little a material is, its properties remain the same. Size, form, color, and mass are the qualities that distinguish a material from non-substances. All of these qualities, including size, shape, color, and mass, can be seen and measured. Some characteristics are physical, while others are chemical. Physical characteristics include mass, volume, density, and color. Viscosity and solubility are examples of chemical qualities.
In the amtmosphere this water vapor cools and turns back to liquid for forming clouds
this process is called condensation. When it cant hold on much longer it will turn into rain or snow.
