Given :
2 Mg + O₂ → 2 MgO
To Find :
How many moles of magnesium oxide are formed if you burn a 2.3 mol sample of magnesium ribbon in the air.
Solution :
From given balanced chemical reaction we can see that 2 mole of Magnesium reacts with 1 mole of O₂ to produce 2 mole of MgO.
Since, there is abundance of oxygen in air.
Therefore, 2.3 moles of magnesium will produced 2.3 moles of magnesium oxide.
1) Uranium
2) Carbon in the form of graphite
3) Palladium
Explanation:
1) In the nuclear reactor the fuel is represented by some uranium isotopes which are easily fissionable.
2) Graphite is made from carbon sheets in which there are free electrons that are moving freely so the carbon, in this form, is able to conduct electricity.
3) Commonly inert electrodes are made from platinum (Pt) or gold (Au) metals, because of the propriety of this metals to not interact chemically very easily with various substances.

X is the gas and Y is the liquid. Intermolecular distances are farther apart in gases than in liquids.
It is important to examine both the colour and the streak of a mineral because the streak may be completely different from the colour of the hand specimen.
The streak of a mineral is the color it possesses after it has been grounded to a fine powder. The streak test has to be done on minerals because it is a more reliable way of identifying a mineral with its color.<span />
