Answer:

3.1\times 10^{25} carbon atoms are present in stone

Explanation:

Diamond is made of carbon only.

1 mg = 0.001 g

1 carat = 200 mg

So, weight of diamond in grams = (3104\times 200\times 0.001)g = 620.8 g

Molar mass of carbon = 12 g/mol

So, number of moles of carbon in diamond is the ratio of diamond to molar mass of carbon.

So, number of moles of carbon in diamond = \frac{620.8}{12}moles

1 mol of an atom = 6.023\times 10^{23} number of atoms

So, \frac{620.8}{12}moles of carbon atom = \frac{620.8}{12}\times 6.023\times 10^{23} carbon atoms = 3.1\times 10^{25} carbon atoms.

What type of reaction is: sulfuric acid + potassium hydroxide -> potassium sulfate + water?
aleksley [76]

Answer:

Double replacement reaction

Explanation:

Now, let us first write the reaction equation properly:

     H₂SO₄ + 2KOH ⇒ K₂SO₄ + 2H₂O

The above reaction is a neutralization reaction between an acid and a base whose product gives salt and water only at most instances.

From here, we can observe that the species displaces on another in their ionic state. Hydrogen replaces potassium and water is produced. Potassium combines chemically with sulfate ions to give the salt of potassium.
