Both. It is slightly negative from one side and slightly positive from the other.
two positive (1) they get water (2) they can get energy from flowing water negative (2) it is polluted (1) it is far distances from their homes
If measuring from sea level, yes. Technically, though, it is accurate to state depth as a negative number, but unless you have been specifically told, it shouldn't matter whether you do or not. The only exception I can think of is if you are drawing a parabola that shows the depth of a buoyant object over a period of time after being thrown or dropped in. It looks a lot neater to show a positive parabola, as a negative parabola could imply that a non-buoyant object was thrown from the bottom of a body of water. I hope this helped, and ignore the previous paragraph if you want.
A subscript is a small number (or letter) placed below and to the right of another number (or letter). Subscripts can mean many different things in different fields of endeavor.In Chemistry the components of a molecule are designated by a letter indicating an element and a subscript indicating the number of those atoms in the molecule (Water = H2O = two hydrogen atoms and one oxygen atom in each water molecule)Subscripts are often used to refer to members in a mathematical sequence or set. For example, in the sequence O = (44, -23, 560), O3 refers to the third member of sequence O, which is 560.
The coefficients are the numbers written in front of the chemical formulas in a chemical equation, and tells how much of a certain substance is involved in the reaction. When there is no number, it is understood to be one. For example, the following equation, which represents the combustion of methane (CH4), could be read in a couple of different ways. CH4 + 2O2 --> CO2 + 2H2O One molecule of methane plus two molecules of oxygen produces one molecule of carbon dioxide plus two molecules of water. or One mole of methane plus two moles of oxygen produce one mole of methane plus two moles of water.
In short, yes. On the left side there is 1 Carbon, 4 Hydrogen and 4 Oxygen. There is the same amount on these on the right. Remember 2H20 is the same as H402. The 2 in front of the water acts upon everything in the molecule.
a molecule having slightly negative and positive ends with regard to change
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
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.
A water molecule is considered a polar molecule because of its shape. That is, its poles contain opposing charges, the positive and negative charge.
A polar molecule such as water
there has to be a negative charge in the molecule as there is a positive charge. there is a negative charge and when it and a positive charge gets together it forms something that makes the charge neutral
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
Water molecule acts like a magnet because positive attracts positive and negative attracts negative.
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.
Surrounds the ions with the hydrogen, positive end, attracted to the negative ion ( Cl -, for instance ) and the oxygen, negative end, attracted to the positive ion ( Na +, for instance ).
Positive. Since the Oxygen atom has a higher electronegativity (it is more likely to draw in electrons) than the Hydrogen atoms, the electrons that are shared in the two oxygen/hydrogen bonds will move closer to the Oxygen atom. This will give the Oxygen atom a slightly positive charge and the 2 Hydrogen atoms a slighty negative charge. Because of this, a water molecule is considered polar.
No. Polar molecules such as water have both negative and positive poles. Different parts of the molecule have slightly different charges.
