one of the many effects is that it may cause floods
water is a polar solvent, it has both a negative and a positive end to it and can therefore surround both the positive and negative ions in a giant ionic lattice, this allows water to break down the solid.
A water molecule is like a magnet in that it has a positive and negative charge distribution. The oxygen atom in water has a slightly negative charge, while the hydrogen atoms have a slightly positive charge, creating a polar molecule. This polarity allows water molecules to attract each other and form hydrogen bonds.
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
A water molecule has a positive area near the hydrogen atoms (due to partial positive charges) and a negative area near the oxygen atom (due to partial negative charges). This is because of the unequal sharing of electrons between the oxygen and hydrogen atoms in water.
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.
as direction of current reverses it is shown in form of positive and negative cycles
a molecule having slightly negative and positive ends with regard to change
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Both. It is slightly negative from one side and slightly positive from the other.
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.
For an electric water heater on alternating current, there is not 'positive' or 'negative'. There should be terminals labeled hot and neutral, though.
It means that water has a positive side and a negative side. This allows polar substances to dissolve well in water.
