What obserb mongo seeds put in water in 5 days?
it did not dissolve in water
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 is the minimum amount of water that will dissolve 5 grams of magnesium sulfate?
1/2 ounce of water, I believe.
How many water molecules are bonded to a glycogen molecule in the liver?
5
When 5 grams of salt dissolve in 30 grams of water what is the resulting mass of the mixture?

Does water readily dissolve most polar compounds?
yes, less than 5 ch2 groups per oh, or nh2 group dissolves in water more does not.
Will an m and m dissolve faster in hotter water?
yes, an m&m will dissolve faster in hot water, because the heat from the water will speed up the molecules in the m&m, and cause it to dissolve faster than it would under cold circumstances.
How many molecules of water make up 5 moles?
for each mole of anything there is 6.022x10^23 molecules. Therefore for 5 moles of water there is 5 x 6.022x10^23 = 3.011x10^24 molecules of water

What is the general rule regarding solubility of polar and non-polar substances?
"Like dissolves like" This is simply stating that a solute will dissolve best in a solvent that has a similar polarity to itself. For example, a very polar (hydrophilic) solute such as NaCl is very soluble in highly polar water and and practically insoluble in non-polar solvents such as benzene. However, a non-polar (lipophilic) solute such as carbon dioxide is insoluble in water and highly soluble in non-polar benzene. For a non-polar solute such as carbon dioxide to become more soluble in water, the pressure of the system would have to be increased. This is why most sodas are under 5 atmospheres of pressure.
Why methanol gives better yield than ethanol?
I do believe that since methanol (CH3OH) is a smaller molecule than ethanol (C2H5OH), and alcohol loses its polarity (and its ability to dissolve polar molecules as well as its own miscibility in water, also a polar molecule) at around 5 carbons or so, then it would follow that perhaps methanol is better at grabbing onto those polar compounds you'd like to extract. Ethanol usually works just fine for long term extraction, and provides a product we can consume.
Five ways that the membrane can deal with materials?
1. Hydrophobic molecules (Hydrocarbons and Oxygen) can cross with ease because they can dissolve in the lipid bi layer. 2. Small polar (uncharged) molecules will pass (water and carbon dioxide). 3. Large polar (uncharged) molecules will not pass (sugar). 4. Ions will not readily pass (H+, Na+, Cl-). 5. Large external materials can be taken in by the cell via endocytosis. 6. Large internal materials can be released by the cell via exocytosis.
Are all ionic compounds polar?
Chemical polarity, also known as bond polarity or simply polarity, is a concept in chemistry which describes how http://www.answers.com/topic/chemical-bond http://www.answers.com/topic/electron are shared between http://www.answers.com/topic/atom. It is a physical property of compounds and affects other physical properties such as http://www.answers.com/topic/solubility, http://www.answers.com/topic/melting-point and http://www.answers.com/topic/boiling-point. Polarity also affects http://www.answers.com/topic/intermolecular-force, leading to some compounds or molecules within compounds being labelled as polar or non-polar.

What are examples of polar covalent compounds?
Acids are all polar covalent to some extent. Probably the most common polar covalent compound is water, H2O. Some other examples are ammonia, NH3, boron trifluoride, BF3, and hydrogen fluoride, HF. Basically, any two atoms with a percentage of ionic character (electronegativity difference) between 5% and 50% will form polar covalent bonds.
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!
Why hydrated salts are not wet?
The water molecules become a part of the crysal structure. 5 water molecules atttach to Cu SO4 to make the hydrated crystal. The reason it is not wet is because the 5 water molecules are more strongly attracted to the CuSO4 than to anything else in its environment. So those 5 water molecules do not wipe off on to your hand, or a towel.
How long does it take a teaspoon of sugar to dissolve in water?
It takes about 5 seconds.
