Answer:
the nucelolo is not part of the atom
Explanation:
The nucleolus is NOT a part of the atom. The nucleolus has its definition in biology as an element of the cell.
Let's remember that the atom is made up of three fundamental elements that are: electrons, protons and neutrons. Protons and neutrons are found in the nucleus while electrons are orbiting around the nucleus.
It should be Carbon dioxide, hope that helps!
Answer:
1.14kg of chalcopyrite
Explanation:
In 1 mole of chalcopyrite, CuFeS₂, there is 1 mole of Cu. Thus, to solve this question we need to convert the mass of pure Cu to moles using molar mass (Cu = 63.546g/mol). Then, the moles of Cu are equal to moles of chalcopyrite that must be converted to grams and then to kg (CuFeS₂: 183.54g/mol)
<em>Moles Cu:</em>
395g Cu * (1mol / 63.546g) = 6.216 moles Cu = 6.216 moles CuFeS₂
<em>Mass chalcopyirite:</em>
6.216 moles CuFeS₂ * (183.54g/mol) = 1140.9g
<em>In kilograms:</em>
1140.9g * (1kg / 1000g) =
<h3>1.14kg of chalcopyrite</h3>
