Answer:
Explanation:
Quantity of copper measured by a student = 4.6 grams
Original quantity of copper = 4.7 grams
Error in measurement = Original quantity of copper - Quantity of copper measured by a student 
grams
To find the percent error, apply the following formula:
Percent error = (Error in measurement / Original quantity of copper) × 100

Which mathematical relationship allows calculation of the equilibrium constant of a reaction if you know the standard change in Gibbs Free Energy ΔG is related to Q by the equation ΔG=RTlnQK. If ΔG < 0, then K > Q, and the reaction must proceed to the right to reach equilibrium
<h3>What is
Gibbs Free Energy?</h3>
The maximum amount of work that may be accomplished by a thermodynamically closed system at constant temperature and pressure can be determined using the Gibbs free energy (also known as Gibbs energy; symbol: displaystyle G). Additionally, it offers a prerequisite for any processes like chemical reactions that might take place in such circumstances.
The maximum amount of non-expansion work that can be taken from a closed system (one that can interchange heat and work with its surroundings but not matter) at fixed temperature and pressure is known as the Gibbs free energy change, which is measured in joules in SI. This maximum is only possible with a fully reversible method.

Answer:
Colours come from electrons moving between shells. The energy of light matches the energy gaps between electron shells.
Explanation:
Electrons are arranged in energy levels (shells) and there are energy gaps between shells. Electrons must be in one shell and cannot be in between. Electrons can move from one shell to another in the right conditions.
When an atoms absorbs energy from heat or light, the atom starts to move a little faster, in other words, it gets warmer. If the energy absorbed is just right to match the energy gap between shells, electrons can jump from one shell to another.
If an object is red, then the energy between gaps during light absorption is equal to the energy of the complementary light color, green.
If the object emits red light, then the energy between gaps during light emission is equal to the energy of red light.
