Copper has an atomic number of 29. that means that there are 29 protons in the nucleus of each copper atom. that’s what the atomic number is; the number of protons in an atom of a certain element. if one copper atom contains 29 protons, how many copper atoms could you make out of 232 protons?

8

Explanation:

1 copper atom has 29 protons so, 1

proton we can say has 1/29 copper atoms

then, 232 protons will make (1/29)×232 copper atoms which is equal to 8

True, A copper ion with a charge of +2 has 29 protons and 27 electrons. The atomic number of an element is equal to the number of protons in the nucleus of each atom of that element. Since copper has an atomic number of 29, all atoms of copper will have 29 protons. This is what identifies an atom as copper.

explanation:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
