Molybdenum monophosphide

Molybdenum monophosphide is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Molybdenum monophosphide rather than just read about it. In short: Molybdenum monophosphide is a binary inorganic compound of molybdenum metal and phosphorus with the chemical formula MoP. Preparation Molybdenum monophosphide can be obtained from electrolysis of molten molybdenum hexametaphosphate: 4 Mo(PO3)6 → 4 MoP + 10 P2O5 + 9 O2 It can also be prepared from heating of a mixture of molybdenum and metaphosphoric acid in a carbon crucible: 2 Mo + 2 HPO3 + 5 C → 2 MoP + 5 CO + H2O…

Reference excerpt

Molybdenum monophosphide is a binary inorganic compound of molybdenum metal and phosphorus with the chemical formula MoP.

Preparation Molybdenum monophosphide can be obtained from electrolysis of molten molybdenum hexametaphosphate:

4 Mo(PO3)6 → 4 MoP + 10 P2O5 + 9 O2 It can also be prepared from heating of a mixture of molybdenum and metaphosphoric acid in a carbon crucible:

2 Mo + 2 HPO3 + 5 C → 2 MoP + 5 CO + H2O Other reactions are known too.

Properties Molybdenum monophosphide forms black crystals of hexagonal crystal system with space group P6m2. It is insoluble in water. Molybdenum monophosphide decomposes when heated in air:

4 MoP + 11 O2 → 4 MoO3 + 2 P2O5

Uses Molybdenum monophosphide can be used as a catalyst.

Worked examples

Example 1 — a first encounter with Molybdenum monophosphide

Start with the simplest possible case. Write down what Molybdenum monophosphide claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Molybdenum monophosphide before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Molybdenum monophosphide ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Molybdenum monophosphide

In research: Molybdenum monophosphide appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Molybdenum monophosphide in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Molybdenum monophosphide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Molybdenum compounds, Phosphides, so understanding it makes those chapters shorter.
In everyday life: Look for Molybdenum monophosphide outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
