What are Conditions needed to cause water to diffuse in cell?
The primary drivinf force for diffusion is a concentration gradient. There has to be an abundance of molecules at one region and a scarcity of molecules at another. This differential distribution of molecules where one region has more than the other is called a concentration gradient. In the presence of this gradient, diffusion occurs without the expenditure of energy. In cells, diffusion can occur through the cell membrane. Water molecules move into or out of the cell depending on where there are more water molecules. If there is more water outside the cell, water molecules move in and vice versa.
Is water a tissue?
No; water is made up of water molecules. Water molecules contain two hydrogen molecules and one oxygen molecule.
Does water evaporate faster in a cup or pan?
Evaporation is the action of molecules escaping the bonds of neighboring molecules. At temperatures above absolute zero, molecules have energy that is expressed in motion. With enough of this motion, water molecules at the surface of water can break the bonds they have with their neighbors. They can escape the liquid and move into the air. When molecules leave the water, there is now less water, which is what we call evaporation. So if you have a dish that exposes more molecules to an area where they can escape the other molecules (in other words, the surface), obviously more will escape. A wide, flat, shallow container exposes many more water molecules to the surface than the same amount of water in a tall, narrow container.
How many more atoms in all do 5 molecules of hydrogen peroxide have than 5 molecules of water?
H2O2 has four nuclei (atoms) in one molecule. Therefore, it has 20 'atoms' in 5 molecules. H2O has three nuclei in one molecule. Therefore, there are 15 nuclei in 5 molecules of water. 20-15 = 5 Ans: 5!
What has more hydrogen distilled or tap water?
They have the same amount of hydrogen. All water molecules have two hydrogen atoms and one oxygen atom.

Why did the solid react in one way in hot water and differently in the cold water?
because hot water has more molecules
Is water a tissue?
No; water is made up of water molecules. Water molecules contain two hydrogen molecules and one oxygen molecule.
How many water molecules are in one ice crystal?
Lots. You didn't specify how big the ice crystal was, so we can't be more specific. There are roughly 33,000,000,000,000,000,000,000 water molecules in one gram of ice.
When water molecules stick to the molecules of other substance the molecules are displaying?
Adhesion is the ability of water molecules to stick to other molecules. Cohesion is the ability of water molecules sticking to one another.
What is more in water hydrogen or oxygen?
There is more hydrogen because H2o, stands for 2 hydrogen molecules with one one 02 molecule

Which one has more molecules 9 g of water or 9 g of suger (C12 H22 O11)?
Since the molecular mass of water is about 18 and the molecular mass of C12H22O11 is about 342, it takes considerably more molecules of water to make up 9 g than molecules of C12H22O11 to get the same mass.
Is lemonade harmful to your teeth then tea?
Yes! Lemonade contains way more sugur and acid then ice tea does. It's one of the most harmful drinks for teeth.
When electricity flows through water the water molecules split into molecules of hydrogen and oxygen gas How many oxygen O2 molecules are produced from the splitting of two molecules of water H2O?
One is produced
When electricity flows through water the water molecules split into molecules of hydrogen and oxygen gas. How many oxygen (O2) molecules are produced from the splitting of two molecules of water (H2O)?
One is produced
What is hydrolosys?
Hydrolosis is a chemical reactioin during which one or more water molecules are split into hydrogen and hydroxide ions
