How many moles of magnesium oxide are formed if you burn a 2.3 mol sample of magnesium ribbon in the air? You must show ALL work

Eva8 [605]

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.

The metal tantalum becomes superconducting at temperatures below 4.483 K. Calculate the temperature at which tantalum becomes su

masha68 [24]

Answer:

The correct answer is "-268.667°C".

Explanation:

Given:

Temperature,

= 4.483 K (below)

Now,

The formula of temperature conversion will be:

⇒ $T(^{\circ} C)=T(K)-273.15$

By putting the values, we get

⇒ $=4.483-273.15$

⇒ $=-268.667^{\circ} C$

Thus the above is the correct answer.
