different substances can react the same way when they're put into solutions. For example - if the substance in the known test was KCl and a precipitate was formed and in the unknown test a precipitate was formed, it may be assumed that the same ion was present. But a different solution, other than KCl may react the same way.

What causes a polar molecule to have positive and negative ends?
A polar molecule has positive and negative ends due to an unequal distribution of electron density within the molecule. This occurs when the electrons are unequally shared between the atoms forming the molecule, creating partial positive and negative charges at different ends of the molecule.
Is Sodium hydroxide polar?
Yes, sodium hydroxide is a polar molecule. It is composed of a sodium cation (Na+) and a hydroxide anion (OH-), which results in an uneven distribution of charge within the molecule. This causes sodium hydroxide to have a partial positive charge on the sodium atom and a partial negative charge on the hydroxide ion, making it polar.
A lack of electircal symmetry in a molecule charge difference in oppsosite ends of a structure?
This lack of electrical symmetry in a molecule leads to a separation of charge, creating a dipole moment. This dipole moment results in the molecule having a positive end and a negative end, making it polar in nature. The unequal distribution of electrons causes one end of the molecule to be slightly more negative, while the other end is slightly more positive.
What causes a molecule to have net dipole moment?
the presence of a net charge that does not cancel out
In hydrochloric acid chlorine has greater electronegativity than hydrogen Therefore?
In hydrochloric acid, the chlorine atom is more electronegative than the hydrogen atom. This causes chlorine to attract the shared electrons in the H-Cl bond more strongly, leading to a partial negative charge on chlorine and a partial positive charge on hydrogen. This results in a polar covalent bond in hydrochloric acid.
What causes static energy?
positive and negative charges
What causes Atom to have a negative or positive charge?
butt
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
Can a positive ANA change to a negative ANA?
Yes, it is possible for a positive antinuclear antibody (ANA) test to change to negative. This could happen if the underlying condition that was causing the positive result resolves or goes into remission. However, it is important to consult with a healthcare provider for proper evaluation and interpretation of test results.
What causes a substance to have a positive charge?
the object has to have more positive charges than negative charges.
Why do some objects have a negative charge and others a positive charge?
atoms often gain or lose electrons,which causes them to have a temporary negative or positive charge.
What are the differences between positive and negative torque in mechanical systems?
Positive torque in mechanical systems causes rotation in one direction, while negative torque causes rotation in the opposite direction. Positive torque is typically associated with tightening or accelerating, while negative torque is associated with loosening or decelerating.
What causes electricity short answer?
In nature there are two types of electricity positive and negative
Is punishment a reinforcer?
Punishment is not a reinforcer. there is Negative Punishment and Positive Punishment, and also Negative Reinforcement and Positive Reinforcement.*Negative Punishment is a consequence withdrawn following a response that causes a behavior to occur with less frequency.*Negative Reinforcement is a consequence withdrawn following a response that causes a behavior to occur with greater frequency.*Positive Punishment is a consequence delivered following a response that causes a behavior to occur with less frequency.*Positive Reinforcement is a consequence delivered following a response that causes a behavior to occur with greater frequency.
What is the major difference between positive and negative feedback?
Positive feedback causes bodily processes to continue; negative feedback causes bodily processes to start or stop only cost you being in my basement
A positive or negative stressor is that causes stress-?
Someone that has stress is a negative for a person. Stress can cause a lot of issues.
What causes chemical compounds to be neutral?
The equal number of positive and negative electrical charges.
