Is pure air a homogenous or heterogenous mixture?
Pure air is considered a homogenous mixture because its components (nitrogen, oxygen, carbon dioxide, etc.) are uniformly distributed throughout and indistinguishable from one another at a molecular level.
Is kerosene a homogeneous or heterogeneous?
Homogenous.
If a chemical reaction has reached equilibrium and you lower the pressure of the system while keeping the temperature constant what happens to the equilibrium of the reaction?
Lowering the pressure will shift the equilibrium towards the side with more moles of gas to counteract the change. If the reaction involves gases, the equilibrium position will shift to favor the side with more gas molecules to increase the pressure back to its original value.
How do you separate gases the air?
Air can be separated into its component gases through a process called fractional distillation. This involves cooling air until it becomes a liquid and then gradually warming it up. Different gases have different boiling points, so as the air warms up, gases like nitrogen, oxygen, and argon vaporize at different temperatures, allowing them to be collected separately.
What are the two types of equilibrium and how are they different?
The two types of equilibrium are static equilibrium and dynamic equilibrium. Static equilibrium is when an object is at rest, while dynamic equilibrium is when an object is moving at a constant velocity with no acceleration. Static equilibrium involves balanced forces in all directions, while dynamic equilibrium involves balanced forces with movement.
