Since gasses weigh nothing when they are produced in a reaction they do not have to be accounted for.

Answer:

Explanation:

You can not have a reaction that produces "no mass". This breaks the law of conservation of mass. When gasses are produced, they will have a specific amount of mass associated with them which means they will have a weight. They will have to be accounted for

A balloon contains a 10% glucose solution. The balloon is permeable to water but not to glucose. A beaker contains a 5% glucose

deff fn [24]

The state of the balloon:

When the balloon is submerged in the beaker, the amount of water in the beaker will get reduced.

What is Osmosis:

Based on the concentration of solutes on both sides of the membrane, water will flow through a permeable membrane in a specific direction.

Hypertonic solution:

It means that there are more solutes present in the surrounding environment than in the cell itself.

Hypotonic solution:

In a hypotonic solution, the concentration of solutes inside the cell is higher than that outside the cell.

When comparing two solutions, the one with the larger solute concentration is hypertonic, and the one with the lower solute concentration is hypotonic. Isotonic solutions have an identical solute concentration.

While the solution in the beaker is hypertonic, Meaning that will draw water molecules out of the cell. As water molecules move from a location of high water potential (dilute solution) to a region of reduced water potential (10% glucose solution), the water from the 5% glucose solution will flow into the 10% one (concentrated solution)
This is the reason why the amount of water decreases when the balloon is submerged in the beaker.

The direction of electrical force is based on the fact that like charges will___each other.

NeTakaya

Answer:

repel

Explanation:

When it comes to electrical forces, "opposites charges attract" while "like charges repel."

There are primarily two types of charges: positive charge and negative charge. The forces they exert upon each other will depend on their charges. The positive charge has an attractive force to a negative charge. On the contrary, it has a repulsive force to the same positive charge. Thus, it will repel each other.

So this means that opposite charges will draw closer together while like charges will move apart from each other.
