A water molecule is composed of a large oxygen atom bonded to two small hydrogen atoms. Which of the following would make the best model of a water molecule?
two small plastic balls attached to a larger plastic ball by toothpicks - apex
What is a large molecule that doesn't dissolve in water?
One is Lipid.
How much volume equals one kilogram?
That depends on the substance that the kilogram is made of. A kilogram of air has a large volume. A kilogram of water has a medium volume. A kilogram of lead or stones has a small volume.
True or false the tiniest bit of water that still is water is a molecule of water?
No. Water is composed of two hydrogen atoms, and one oxygen atom. Both of these can exist as pure elements in the form of H2 and O2, respectively. Since a hydrogen (H) atom has the fewest number of protons and electrons, at one a piece, H2, the binding of two of this smallest atom, is the smallest molecule.
Which the two structure in plant cell are selectively permeable allowing molecules of water and small solutes to pass through but preventing the passage of large solute molecule?
Cell membrane and sap vacuole membrane

How many water balloons will it take to fill your gymnasium?
It all really depends on the size of the water balloon and your aim. Good aim, and large water balloons? Four or five should do the trick. Good aim, and small water balloons? Double how many it took with large water balloons. Well, you can see where I'm going from here. (:
What are the different sizes of water droplets?
because depending on the condensation and the humidity of the air they can be all different sizes from really small to as big as marbles.3
What is an example of a large molecule in a living organism?
water (H20)
What is the breakdown of large molecule by the enzymatic addition of water is?
hydrolysis
What is a large molecule that doesn't dissolve in water?
One is Lipid.
What does a picture or a molecule of water look like?
Very small
How big is a water molecule in scientific notation?
very small
Is a molecule of water 'wet' like a puddle is wet?
No. the puddle itself is not wet. A puddle of water is considered wet because when you put something in it (your shoe, your newspaper, your mcmuffin) it comes out wet. a molecule of water is too small to moisten anything large enough so that we can have a wet/dry comparison.
Is the marginal benefit of a glass of water large or small?
water is necessary for life, is the marginal benefit of water is large or small?
In which part of the body digests water?
Water is already a very small molecule with only three atoms and so it does not need to be digested (broken down) any further to be absorbed. The organ that aobsorbs water is the large intestine.
Is excess water reabsorbed from the small or large intestine?
The small intestine absorbs food and the large intestine absorbs water.
