Answer:
The answer is "
"
Explanation:
The water solution of PbCl2 is poor. It also has 2 distinct dissolving properties. In cold water, this will not dissolve easily.It is water-insufficiently soluble. And that in cold water, it is indeed insoluble. That's why we know that all energy should be available for a solid to dissolve in the liquid to counteract that attractive force between the ions in the grid.
Answer:
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension
Explanation:
Explanation:
Kinetic energy is defined as the energy obtained by an object due to its motion. Whereas energy obtained by an object due to its position is known as potential energy.
(a) When a sled is resting at the top of a hill then it means the sled in not moving. Hence, then it has only potential energy. But when a sled sliding down the hill then it is moving from its initial position.
Hence, when a sled is sliding down the hill then it has higher kinetic energy.
(b) When water is above the dam then it only has potential energy but when the water falls over the dam then it has higher kinetic energy.
Explanation:
Gravitational potential energy
= mgh
= (5kg)(9.81N/kg)(150m)
= 7357.5J.
Answer:
Explanation:
Given that the volume is 
The air flows (F) at the rate of 
. The concentration of carbon monoxide in the air is 5%.
Let Q be the amount of the carbon monoxide present in the room at time t. then,
Also,
Thus,
