Answer:
b/(b+a)
Step-by-step explanation:
(1/a)-(1/b) :[ (b²-a²)/ab²]
first solve :
common denominator ab
(1/a)-(1/b) = (b-a)/ab
[b-a/ab] : [(b²-a²)/ab²]
when divide fraction ( division sign turn to (×) and flip the second fraction(reciprocal):
[b-a/ab] × [ab²/ (b²-a²)]
then simplify : ab²/ab = b
(b-a)×(b/b²-a²)
factorize : b²-a² = (b-a)(b+a)
(b-a)×(b/(b-a)(b+a)) simplify : (b-a)/b-a = 1
[(b-a)(b)]/[(b-a)(b+a)
b/b+a

The type of model shown in the structure of water given above is ball-and-stick model
The atomic structure consists of two hydrogen atoms and one oxygen atom (H-O-H)
However, water has some characteristics which makes it unique from other liquids. These characteristics include the following:
- Water is less dense as a solid than as a liquid.
- Water is polar
- Water is an excellent solvent
- Water has high heat capacity
- Water has high heat of vaporization.
- Water has cohesive and adhesive properties.
- Pure water is colorless
- Pure water is always tasteless and odorless.
<h3>What is a compound?</h3>
A compound is a substance which contains two or more elements which are chemically combined together.
Below are some examples of chemical compounds:
- Sodium hydroxide
- Calcium carbonate
- Tetraoxosulphate vi
So therefore, the type of model shown in the structure of water given above is ball-and-stick model
