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
A water molecule has a positive end (hydrogen) and a negative end (oxygen) due to the uneven distribution of electrons. This makes water a polar molecule.
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 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.
A polar molecule such as water
A polar molecule is one that has a negative and positive end due to an uneven distribution of electron density. Water is a common example of a polar molecule, with its oxygen atom being partially negative and its hydrogen atoms being partially positive.
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
The positive calcium ions in calcium chloride are attracted to the negative oxygen atom in the water molecule, while the negative chloride ions are attracted to the positive hydrogen atoms in the water molecule.
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.
Water dissolves many compounds because of its polarity. The water molecule has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom, allowing it to interact with both positively and negatively charged ions in the solute molecules, facilitating their disassociation and dissolution in water.
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 ).
Polar molecules like water do have distinct positive and negative poles due to an uneven distribution of charge within the molecule. In the case of water, the oxygen atom has a partial negative charge, while each hydrogen atom has a partial positive charge, resulting in a polar molecule.
