If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
Answer:
The force of the gases pushes downward at the same time that the gases push the rocket upwards. 1.
Explanation:
Answer:
Cohesion
Explanation:
Cohesion tension theory of water movement up the tree vessels
Cohesion is the term used to describe the binding forces present in water molecules through hydrogen bonds as such the water molecules have considerable tensile strenghth allowing them to be pulled up into the leaves of plants through the tree vessels without breakage as longitutudinal stress are placed on the water as it is pulled up
I would say true because the Valence Shell Electron Pairs will Repel each other. When they do they are forced to the opposite side of the Carbon atom giving CO2 a linear molecular shape. The CO2 bond angle will be 180 degrees since it has a linear molecular geometry.
sorry if im wrong
