What else can I help you with?
The first element in a compound is positive and the second one is negative.?
false
What is the difference in the strength of attractions between polar as nonpolar molecules?
No. A polar molecule (such as water) has partial positive and negative charges at each end, but these partial charges balance out to zero overall, leaving the molecule as a whole neutral. This is due to electrons being shared unevenly be the atoms in the molecule. A "charged molecule" would not be called a molecule. It would be called a polyatomic ion. A polyatomic ions has an overall net charge due to there being a different number of protons and electrons.
Treu or false Atoms have a positive charge?
An atom may be neutral, or it may have a positive or a negative charge. If it has a charge, it is called an ion.
Thunder occurs when positive and negative electrical charges build up in the clouds.?
False A+
A cation has a positive charge chromophores are always anions true or false?
False. Chromophores are functional groups or chemical compounds that give color to molecules. They can be present in cations, anions, or neutral molecules. The charge of the molecule does not determine the presence of chromophores.
True or false Water is an example of a polar molecule?
True. Water is a polar molecule because it has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom due to differences in electronegativity. This polarity allows water to form hydrogen bonds with other water molecules.
Is it true that in a water molecule the electrons within the molecule are attracted more towards the hydrogen atoms?
Water is a polar molecule where the electrons spend more time in orbitals around the oxygen atom because it is significantly more electronegative than the hydrogen atoms. So, false is the answer.
How do you beat a false positive?
you can have a false negative but NOT a false positive
Is a false positive a negative?
No.
Integers can be positive or negative true or false?
False - if the sentence is meant to be exhaustive. Integers can be positive or negative OR ZERO.
What is more serious getting a false negative or a false positive?
Positive = You really did it. False Positive = The test said you did it, but you really did not.
Can a positive pregnancy test turn negative?
No , but a negative test can be a false positive .
Sum of a positive integer and a negative integer always positive true or false?
False.
Could an error in a pregnancy test result in a false positive or false negative outcome"?
Yes, an error in a pregnancy test could lead to a false positive or false negative result.
Over-inoculation of the slide with organisms in a wet mount would be a false positive or false negative?
I believe false positive
Is -n always names a negative number true?
Is false. If ' n ' is negative, then ' -n ' is positive.
The first element in a compound is positive and the second one is negative.?
false
