Answer: The measure of angle S is 62 degrees.
There are 2 ways to find the answer.
First, the triangles are similar. That means that all the angles will be the same. Since, angle S is corresponding to angle B, it will have the same measure.
Second, there are always 180 degrees in a triangle. Therefore, we can write and solve the following equation about the angles in triangle SQR.
x + 41 + 77 = 180
x + 118 = 180
x = 62
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
