The maximum mass of B₄C that can be formed from 2.00 moles of boron (III) oxide is 55.25 grams.
<h3>What is the stoichiometry?</h3>
Stoichiometry of the reaction gives idea about the relative amount of moles of reactants and products present in the given chemical reaction.
Given chemical reaction is:
2B₂O₃ + 7C → B₄C + 6CO
From the stoichiometry of the reaction, it is clear that:
2 moles of B₂O₃ = produces 1 mole of B₄C
Now mass of B₄C will be calculated by using the below equation:
W = (n)(M), where
- n = moles = 1 mole
- M = molar mass = 55.25 g/mole
W = (1)(55.25) = 55.25 g
Hence required mass of B₄C is 55.25 grams.

The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.
<h3>What is a synthesis reaction?</h3>
A synthesis, or combination reaction, is a kind of reaction in which two substances combine to form a bigger molecule.
The generic reaction is:
a + b = c
Some common synthesis reactions are:
- Two elements combine to form a compound.
Fe + S = FeS
- One element and one compound combine to form a compound.
O₂ + 2 SO₂ = 2 SO₃
- Two compounds combine to form another compound.
CaO + CO₂ = CaCO₃
In all the examples above, we can verify that the substances (elements or compounds) combine with each other to form another substance (product).
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.

I actually do not know the answer can I help tommorow if you are fine with it tooo sleeeepy have 14 exams tommorow have to prepare.
Sorry:(
Answer:
D) Van der Waals
Explanation:
Given that the geometry is linear, one finds that the C = O bonds cancel out any polar effects due to the linear geometry ( O = C = O )and gives the molecule a net dipole of zero. Interactions are therefore dependent upon dispersion forces that are classified as Van der Waal Forces or London Forces.
