Copper forms a green deposit on its surface when exposed to air which is usually a mixture of copper carbonate and copper hydroxide.
Polar molecules are characterize by an imbalance of electrostatic forces between the molecules. It arises when the electronegativity of the elements differ greatly. Since there is a great difference of the partial charges, the intermolecular or intramolecular force involved here is the electrostatic bond.
<span>The metal also gives off heat in the form of radiation.
Just took the test and got it right, using a process of elimination based on what you know helps. Hope this helps!</span>
N₂ + 3H₂ ⇒ 2NH₃
doesnt matterN₂ + 6.64H₂ ⇒ 2NH₃
(6.64H₂/3H₂) x (2NH₃) =4.4266667
rounded to sig figs= 4.43
