Explanation:</h3>
We need to answer the following questions
What is a wave?
- A wave refers to a transmission of a disturbance from one point to another. It involves transfer of energy from the source to other points.
What are the major types of wave?
- Waves may be classified as longitudinal waves or transverse wave based on the vibration of particles relative to the direction of transmission.
What is a transverse wave?
- A transverse wave is a wave in which the vibration of particles is perpendicular to the direction of transmission of the wave.
- This type of wave contains highest points known as crests and lowest points known as troughs.
Since there is more energy added as heat rises, the particles disperse and have larger movements.
Answer:
(C) Oxygen because it has the strongest attractive force and the largest
electronegativity
Explanation:
Oxygen will be most reactive
configuration = 
As oxygen need only two electrons to complete its octet.
Oxygen will have stronger force than nitrogen as it will tend to pull electrons more to complete its octet. Also along the period electronegativity increases so oxygen has higher electronegativity than nitrogen
Answer:
The rate is a mathematical relationship obtained by comparing reaction rate with reactant concentrations.
Au^2S^3+ 3H^2 = 2Au + 3H^2S
