If a molecule has an empirical formula of C2H2O and a molecular mass of 84.0 g/mol, what is the molecular formula?
lord [1]

Answer:

=C₄H₄O₂

Explanation:

Given the empirical formula of a molecule, the he the quotient of the molecular mas and and the empirical mass=constant.

84.0 g/mol/mass of(C₂H₂O)=constant

=84/(12×2+1×2×16)

=84/42

=2

Therefore, the molecular formula is (C₂H₂O)₂=C₄H₄O₂

What happens to the electrons in an ionic bond and a covalent bond?
irina1246 [14]

Answer:

In ionic bonding, atoms transfer electrons to each other. Ionic bonds require at least one electron donor and one electron acceptor. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.

Which statement defines dynamic equilibrium? (5 points)
Shalnov [3]

Answer:

1. A state of balance in which the rates of the forward and reverse reactions are equal.

Explanation:

A dynamic equilibrium is like a cycle, the reactants change to products, but the products also change to reactants keeping the amount of each constant.

2. A state of balance in which the forward reaction stops but reverse reaction continues.

In this statement there isnt a equilibrium. The products will change to reactants until the reaction stops.

3. A state of balance in which the forward reaction continues but reverse reaction stops.

Here the reactants will change to products until the reaction stops.

4. A state of balance in which the forward and reverse reactions stop.

In this case the reaction has stopped.
