Which of these properties of water cannot be attributed to hydrogen bonding between water molecules?
non polar molecule
What forces between water molecules are responsible for many of water's unusual physical properties?
hydrogen bonds
State the condition under which a microwave oven heats up a food item containing water molecules most efficiently?
Many molecules (such as those of water) are electric dipoles, meaning that they have a positive charge at one end and a negative charge at the other, and therefore rotate as they try to align themselves with the alternating electric field induced by the microwaves. This molecular movement creates heat as the rotating molecules hit other molecules and put them into motion. Microwave heating is most efficient on liquid water, and much less so on fats and sugars (which have less molecular dipole moment), and frozen water (where the molecules are not free to rotate).
Why does a water drop form a sphere?
Water (H2O) is very cohesive, meaning that its molecules tend to stick to each other. Cohesion of water is especially strong due to an H2O's ability to make up to 4 hydrogen bonds with other water molecules. This principle is also responsible for the common elementary experiment in which many drops of water are dropped on a penny head, yet the water manages to stay on top. Its cohesiveness is due to
How many electrons in the electron cloud does argon have?
18
After cloud droplets form what must happen to them for precipitation to occur?
Many water molecules condense on a tiny particle.
In a month your house is destroying how many ozone molecules?
A single household destroys many ozone. A single CFC even can destroy 100,000 molecules.
How many molecules of water are present in 1g of water?
The answer is 0,166.10e23 molecules.
What is a cloud droplet?
A tiny amount of liquid water, of microscopic size -- though still containing a huge number of water molecules. Many droplets must merge to form just one normal-size drop of water.
How many molecules of water H20 contain2.60x1023molecules of water?
Of course, 6,022.10e23 molecules.
How many molecules of water does a 50g sample of H2O have?
The number of water molecules is 16,728.10e23.
How many molecules of water are in 5.65 moles of water?
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
How many water molecules are present in magnesium sulphite?
Magnesium sulfite has 6 water molecules.
36g of water have how many molecules?
36g water contains 12.046 x 1023 molecules.
How many water molecules in a can of soda?
water molecules in a can of soda = (wt/M.wt) x 6.023x1023
How many water molecules are formed in the electron transport chain?
12 water molecules are made.
How many molecules of hydrogen in water?
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
