There are 5.66 moles of hydrogen in the sample of talc(hydrated magnesium silicate).
Given,
Talc formula is 
moles of magnesium = 8.5 moles
The stoichiometry of magnesium and hydrogen is 3 : 2,
So 3 moles of magnesium is equivalent to 2 moles of hydrogen.
Then 8.5 moles of magnesium is equivalent to
=5.6666 moles
<h3>Talc </h3>
Talc(hydrated magnesium silicate), often known as talcum, is a type of clay mineral made up of hydrated magnesium silicate, having the formula Mg3Si4O10(OH)2. Baby powder is made of powdered talc, frequently mixed with corn starch. This mineral serves as a lubricant and thickening agent. It serves as a component in paint, pottery, and roofing materials. It serves as a key component in many cosmetics. It can be found as foliated to fibrous aggregates and in a remarkably uncommon crystal form. It is foliated with a two-dimensional platy form, has a flawless basal cleavage, and an irregular flat fracture.
Talc(hydrated magnesium silicate), the softest mineral, is assigned a value of 1 on the Mohs scale of mineral hardness, which is based on scratch hardness comparisons.

Answer:
Decomposition reaction
Explanation:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
The given reaction is decomposition reaction.
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
