When acid and base are mixed form?
Forms water because acid and base reactions results to being neutral to one another which gives off a water or salt.
What are two molecules with charged ends?
Molecules that have charged ends are polar. The poles are only slightly charged, so they do not have the strength of ions, so they do not form chemical bonds with one another, however they do form weak attractions with one another. Water is the classic example of a polar molecule. The oxygen atom is larger and more electronegative than the hydrogen atoms. So the oxygen end of a water molecule has a slight negative charge and the hydrogen end has a slight positive charge. The oxygen atom of one water molecule will form a weak attraction with a hydrogen atom of another water molecule. This type of attraction is called a hydrogen bond.
In which form of substance do the molecules have the strongest attractions to one another?
solid because the molecules are packed closely together
When two water molecules react what do they create?
Two water molecules can react to from hydrogen bonds. If one water molecule acts as an acid and donates a proton to another water molecule then hydronium ions an hydroxyl ions can be formed as well.
Describe where a hydrogen bond can from among water molecules?
In one water molecule, you have the slightly negatively charged oxygen side, and then you have the slightly positive hydrogen end. Because of this, the negative oxygen attracts positive hydrogens and vice versa in separate water molecules. This is where the hydrogen bonds are made.
Can energy Chang from one form to another?
yes
What are the main water sources in Northwest China?
The hung river, the Chang Chang, and the yellow river.
The movement of water from place to place and from one form to another form is called?
runoffs
Can a rock chang to a type of rock to another?
rocks can change from one type of rock to another, or not change at all
Why does the amount of water that flows in a river chang during the year?
one Answer EVAPORATION
How is energy used in the water cycle?
Energy gets converted from one form to another. Hence, it participates in water cycle.
Does the earth moving on its axis cause water to change from one form to another?
no it just changes the temp.
What are the three forms of water change from one form to another?
These three forms are: liquid, gas and solid.
What transfers chemicals form one location to another to weather objects?
Rain and bodies of water, such as rivers
What happens when many water molecules come into contact with one another Explain?
they form hydrogen bonds
What happen to energy during the water cycle?
Energy gets transformed from one form to other. It transfers from one state to another.
Where was flowing water developed?
The aqueducts were constructed to help water flow from one location to another. The Romans were the first to construct a form of plumbing system.
