Answer : The amount of sodium oxide produced is, 74.40 grams
Solution : Given,
Mass of sodium = 55.3 g
Mass of = 64.3 g
Molar mass of sodium = 23 g/mole
Molar mass of = 32 g/mole
Molar mass of = 61.9 g/mole
First we have to calculate the moles of sodium and oxygen.
Moles of Na =
Moles of =
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction will be,
From the balanced reaction we conclude that
4 moles of sodium react with 1 mole of oxygen
2.404 moles of sodium react with moles of oxygen
Excess moles of oxygen = 2.009 - 0.601 = 1.408 moles
That means sodium is a limiting reagent and oxygen is an excess reagent.
Now we have to calculate the moles of sodium oxide.
From the reaction we conclude that,
4 moles of sodium react to give 2 moles of sodium oxide
2.404 moles of sodium react to give moles of sodium oxide
Now we have to calculate the mass of sodium oxide.
Therefore, the amount of sodium oxide produced is, 74.40 grams

When gold is hammered it "squishes". Iron Pyrite is

Gold is a malleable metal, able to deform without breaking when hammered. On the contrary, Iron Pyrite or 'Fool's Gold' is brittle; it shatters when struck due to its lack of malleability.
Gold is known as a malleable metal, which means it can be hammered or bent into different shapes without breaking. In contrast, Iron Pyrite, often known as 'Fool's Gold', is brittle, meaning it will shatter or break when struck by a hammer.
Malleability is a physical property of metals that allows them to be hammered or rolled into thin sheets. Gold is one of the most malleable metals and can be hammered into extremely thin sheets.
On the other hand, a brittle material like Iron Pyrite lacks this property of malleability. Instead of deforming under stress, it will fracture, this is why it shatters into many pieces when struck.
