Binary ionic compound of calcium and oxygen

Explain why one molecule of nabh4 will reduce only two molecules of m acetylbenzaldehyde to form the corresponding product

Sergeeva-Olga [200]

One molecule of nabh4 will reduce only two molecules of m-acetylbenzaldehyde to form the corresponding product because there are only two functional groups that can react with NaBH4, namely the ketone and the aldehyde, but NaBH4 had four H present to protonate the molecule.

What is protonation?

An atom, molecule, or ion can be protonated by adding a proton to it. The difference between protonation and hydrogenation is that during protonation, the protonated species' charge changes, whereas it remains unchanged during hydrogenation. Numerous catalytic processes result in protonation.

A conjugate acid is created when a proton (or hydron, or hydrogen cation), (H+), is added to an atom, molecule, or ion. Deprotonation is the analogous process that occurs when a proton is taken out of a Bronsted-Lowry acid.

Iron and carbon monoxide are made by heating 5.53 kg of iron ore, Fe₂O₃, and carbon. What is the theoretical yield of iron in ki

vfiekz [6]

Answer:

Mass of Fe produced = 3.86785211069 ≈ 3.87 kg

Explanation:

From the question the chemical reaction can be written as follow :

Fe2O3 + C → Fe + CO

Balance the equation

Fe2O3 + 3C → 2Fe + 3CO

compute the molecular mass of Fe2O3 and atomic mass of Iron(Fe)

Molecular mass of Fe2O3 = 55.845(2) + 15.999(3) = 111.69 + 47.997 = 159.687 g

Atomic mass of iron = 55.845 g

From the balanced equation

159.687 g of Fe2O3 produces 2 × 55.845 = 111.69 g of Fe(iron)

Convert the 5.53 kg to gram

1 kg = 1000 g

5.53 kg = 5.53 × 1000 = 5530 g

since,

159.687 g of Fe2O3 produces 2 × 55.845 = 111.69 g of Iron(Fe)

5530 g of Fe2O3 will produce

cross multiply

Mass of Fe produced =5530 × 111.69/159.687

Mass of Fe produced = 617645.7

/159.687

Mass of Fe produced = 3867.85211069 g

convert to kg

1000 g = 1 kg

3867.85211069 = 3867.85211069/1000

Mass of Fe produced = 3.86785211069 ≈ 3.87 kg

What properties does a substance have to have to be a mineral?.

UkoKoshka [18]

Answer:

the description of a mineral species usually includes its common physical properties such as habit, hardness, lustre, diaphaneity, colour, streak, tenacity, cleavage, fracture, parting, specific gravity, magnetism, fluorescence, radioactivity, as well as its taste or smell and its reaction to acid.
