In a redox reaction electrons are lost and gained in equal numbers. The species that is oxidized gives electrons to the species that is reduced. I hope this helps. Let me know if anything is unclear.
Answer: Evaporation
Explanation:
When the heat of the sun touches the water, the water molecules heat up and move gradually faster. Over time molecules start to pop out the surface of the water individually.
And then eventually all the water is evaporated into water vapor.
Answer:
Option D
Oxygen particles mix evenly with hydrogen particles.
Explanation:
Diffusion refers to the movement of gasses from a region of higher concentration to a region of lower concentration.
Diffusion occurs in gases because their particles are in a state of constant random motion.
Due to this continuous random motion, once the oxygen and the hydrogen are added to the container, they will begin to mix freely with each other until they fill up the entire volume of the container.
Answer:

Explanation:
The expression for centrifugal force is shown below as:-

Where, m is the mass of the object = ?
v is the velocity of the object = 7.60 m/s
r is the radius
F is the force = 222 N
Diamter = 11.6 m
Radius = d/2 = 11.6 m/2 = 5.8 m
Applying the values in the above expression as:-



Answer:
Electrical Energy
Explanation:
Batteries store chemical energy and change it to electrical energy.
