Answer:
Copper is a metal made up of copper atoms closely packed together. As a result, the electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons because they help copper be a good conductor of heat and electricity.
Explanation:
MgCl2
Mg=24
Cl=35.5×2 = 71
rmm= 71+24=95g
1 mole = molar mass
1 mole = 95g
1g = 1/95 moles
345g= 1/95 × 345
3.6 moles
Answer:
He conducted an experiment using gold foil and alpha particles.
Explanation:
Ernest Rutherford in 1911 performed the gold foil experiment which provided a better outlook to the structure of the atom. In his experiment, he bombarded a thin gold foil with alpha particles. Most of the alpha particles passed through the gold foil and just a few was deflected back.
This observation led Rutherford to propose the nuclear model of the atom in which an atom has a small positively charged centre and electrons moving round it.
The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature.
<h3>What is Maxwell-Boltzmann distributions?</h3>
The Maxwell-Boltzmann distributions is a description of the speeds of different gases at the same temperature. Recall that at the same temperature, the relative speed of gas molecules is described by the Maxwell-Boltzmann distributions.
The question is incomplete hence we can not be able to show the exact relationship between the two graphs in order to arrive at a justification for the student's claim.

Answer:
1. carboxyl group is removed from pyruvate and releases 1 co2 molecule and leaves 2 carbon molecules
