tatuchka [14]

Answer:

The correct option is D

Explanation:

The major raw material used in making cement clinker is limestone. This limestone is usually mixed and heated with clay and can sometimes be mixed, in addition to the clay, with fly ash, black ash, bauxite, iron ore and gypsum. <u>However, the product cement clinker contains different calcium silicates and/or aluminates such as Ca₃SiO₅, Ca₃Al₂O₆, Ca₂(Al,Fe)₂O₅ and Ca₂SiO₄</u>. Thus, the correct option is D.

Calculate how many grams of o2(g) can be produced from heating 87.4 grams of kclo3(s).
Rufina [12.5K]
<span>34.2 grams Lookup the atomic weights of the involved elements Atomic weight potassium = 39.0983 Atomic weight Chlorine = 35.453 Atomic weight Oxygen = 15.999 Molar mass KClO3 = 39.0983 + 35.453 + 3 * 15.999 = 122.5483 g/mol Moles KClO3 = 87.4 g / 122.5483 g/mol = 0.713188188 mol The balanced equation for heating KClO3 is 2 KClO3 = 2 KCl + 3 O2 So 2 moles of KClO3 will break down into 3 moles of oxygen molecules. 0.713188188 mol / 2 * 3 = 1.069782282 mols So we're going to get 1.069782282 moles of oxygen molecules. Since each molecule has 2 atoms, the mass will be 1.069782282 * 2 * 15.999 = 34.23089345 grams Rounding the results to 3 significant figures gives 34.2 grams</span>

Hydrogen fluoride is used:
Simora [160]

Answer: The correct answer is option B)

in the synthesis of cryolite for aluminum production.

Explanation:

Hydrogen fluoride (HF) is used in synthesis of cryolite for aluminum production.

HF is a gas that dissolves in water to form hydrofluoric acid. However, HF also react with halogenated alkanes like trichloromethane CHCl3 to form organofluorine compounds that serves as precursors in the synthesis of cryolite, an Ore from which aluminum is produced
