Oxygen dichloride molecule consists of an oxygen atom and two chlorine atoms. According to the VSEPR theory, the 3-D shape of the compound is bent.
There are 6 valence electrons in the oxygen atom and each chlorine atom has 1 valence electrons. Therefore, there are 8 valence electrons or 4 pairs of valence electrons.
According to VSEPR theory, due repulsion between 4 pairs of valence electrons, bond angle between two O-Cl bonds becomes 110 degrees and the shape of the molecule of the compound becomes bent.
Answer:
The Curies established that radioactivity is a property of an atom that does not change if changes occur to the physical or chemical properties of the atom.

Answer:
One, It can help children to easily learn or recognize the structure of the brain.
Second, It can help children to learn about the ridges and groves, blood vessels in the brain which will grow curiosity in them to do more research about the stucture and function of the brain.

I hope this helps :)
Answer:
E to F
Explanation:
We know that v = dx/dt
and a = d²x/dt²
Decreasing velocity means deceleration or negative acceleration,
therefore d²x/dt²<0
i.e the portion where the graph is having its curvature downwards like an inverted u, from graph E to F portion looks like that.
Therefore in the portion E to F velocity decreases.
