Answer:
In the last chapter we looked at the particle model of matter and specifically at changes of state. Do you remember heating and cooling candle wax to observe it melt and then solidify. The wax first changed from a solid into a liquid and then back to a solid again. These are physical changes. The chemical properties of the substance does not change.
We are now going to look at what happens when we get chemical changes in substances. These take place during chemical reactions.
Answer is: Velocity and spacing of particles is reduced and Volume of substance decreases relative to temperature decrease.
Charles' Law (The Temperature-Volume Law) - the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature:
V₁/T₁ = V₂/T₂.
When temperature goes down, the volume also goes down.
Velocity is equivalent to a specification of its speed and direction of motion, it is a physical vector quantity. Less enegry (lower temperature), lower the velocity.
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
The concentration of copper in the solution is
The volume of the solution = 1.00 L
Overall balanced equation of reaction is,
Mole ratio for,
Remained moles of en are= (0.00120-0.000500)
The concentration of copper in the solution is,
Therefore, the concentration of copper in the solution is
