Does Sugar dissolves in water because the positive ends of the sugar molecules are pulled off the solute surface by the negative ends of the water molecules?
Yes
Lipis are what molecules because they have no negative and positive molecules?
Polar?
If sugar dissolves in tea is it positive or negative?
Sugar dissolves in water because both water and sugar are polar.
Water dissolves many ionic and molecular compounds because of its what?
Water is a highly polar molecule which means that one side of the molecule is slightly positive and the other is slightly negative. This means that water molecules are attracted and can form weak bonds with molecules that also have positive sides and negative sides (polar molecules). Basically, the positive side of the water molecule is attracted to the negative side of the polar molecule and the negative side of the water molecule is attracted to the positive side of the polar molecule. Is this way the water is able to surround and separate the polar molecules. The story is much the same for an ionic compound which contains a mixture of positive and negative ions. The positive side of the water molecules surround the negative ions and the negative side of the water molecules surround the positive ions.
When a certain solid dissolves in water the solution becomes cool Is ΔHsoln for this solute positive or negative?
Positive, because as the solution forms, heat is absorbed. This answer was correct on WileyPlus
Explain how the polarity of the water molecule makes it a versatile solvent?
Because the positive hydrogen atoms of the water molecule attach with and dissolve the negative atoms of other molecules, and the negative oxygen atom attaches and dissolves the positive atoms of other molecules.
How is water molecule like a magnet?
Water molecule acts like a magnet because positive attracts positive and negative attracts negative.
Does sugar dissolve in water because the positive ends of the sugar molecules are pulled off the solute surface by the negative ends of the water molecules?
Yes
How do water molecules dissolve in water?
Well, if you add water to water, the first water dissolves into the second water. But when that happens, it just makes more water. That shows that water does not dissolve water. So you can't dissolve water in water. Hope the answer was useful!
Why do you think polar and nonpolar molecules do not mix?
Polar molecules happen when there is an unequal sharing of electrons in a covalent bond. This leads to a partial positive change on one molecule and a partial negative charge on the other. An example of this is water (H2O). The hydrogens have partial positive charges and the oxygen has a partial negative charge.
Is a positive divided by a negative a negative?
yes because a negative X a negative is a positive, thus a positive/a negative=a negative
What is negative seven in Parentheses to the second power?
positive 49 Because a negative times a negative is a positive. -7*-7=49. positive * positive = positive negative * negative= positive positive * negative = Negative
