As long as the chemical is not used up in the reaction the answer is true
<u>Chemical</u>. The copper atoms form new chemical bonds with atoms in the air.
We have that every gas satisfies the fundamental gas equation, PV=nRT where P is the Pressure, V is the volume of the gas, n are the moles of the gas, R is a universal constant and T is the Temperature in Kelvin. We have that PV/T=nR and during our process, the moles of the gas do not change (no argon enters or escapes our sample). See attached.
Answer:
it would be a covalent bond
Explanation:
carbon has 4 valence electrons, while chlorine has 7.
