Why is water considered to be a complex compound
2 answers:
Compounds contain two or more different elements.
Water is a molecule because it contains molecular bonds . Water is also a compound because it is made from more than one kind of element. (oxygen and hydrogen).
So If you like, you can say that water is a molecular compound.

Answer:
Water is a simple compound.
Explanation:
Water, from first glance, is a simple compound. This is because it is made up of two atoms - hydrogen and oxygen. This gives the formula:
In the simple compound, one atom of oxygen is bound to two hydrogen atoms like this:
The bonding in water is hydrogen bonding. This is a bonding that takes place between the oxygen atom and a hydrogen atom of the next water molecule.
This makes the water molecule an interesting molecule.

Answer:
A. α = - 1.047 rad/s²
B. θ = 14.1 rad
C. θ = 2.24 rev
Explanation:
A.
We can use the first equation of motion to find the acceleration:
where,
ωf = final angular speed = 0 rad/s
ωi = initial angular speed = (30 rpm)(2π rad/1 rev)(1 min/60 s) = 3.14 rad/s
t = time = 3 s
α = angular acceleration = ?
Therefore,
<u>α = - 1.047 rad/s²</u>
B.
We can use the second equation of motion to find the angular distance:
<u>θ = 14.1 rad</u>
C.
θ = (14.1 rad)(1 rev/2π rad)
<u>θ = 2.24 rev</u>
