A physical property of an element is a property of an element that can observed or measured without changing the chemical nature of the element.
A chemical property of an element is a property of an element that can only be observed or measure when the chemical property of the element is altered or changed.
Based on this;
The boiling point of bromine is a physical property of bromine.
The high reactivity of bromine with many elements is a chemical property of bromine.
Answer:
B
Explanation:
The carbon-oxygen double bond is polar.
However, carbon dioxide is a linear molecule. The two dipoles cancel out each other.
Thus, carbon dioxide is a non polar molecule with polar bond.

Remeber:
Kinectic energy = [1/2]mv^2
Potential energy = m.g[h - h0]
6. When the snowboarder is still at the top, she does not have kinetic energy, given that the speed is zero.
There, at the top, the potential energy is maximum, given that the height, h - h0, is the highest.
So, ar the topo she only has potential energy.
7. From that point, the snowboarder, starts to gain velocity; is has started a process of conversion of potential energy to kinetic energy. More velocity, less height, more kinetic ener energy and less ptential energy.
At the very bottom, when she has reached the heigth of reference, h0, the term [h - h0] becomes zero, then the potential energy has dissapeared and all the energy has been transformed into kinetic energy; the speed and the kinetic energy are maximum.
