I've done this a few times and keep coming up with 5.0 L . I used the mole ratio, and SO 2 as the LR. That would make 2 moles of SO3 5.0 L but its not one of your choices. the temp and pressure are constant, so according to n/v = p/rt the volume is the same as the moles. hope this helps
Answer:
The three definitions are listed in the explanation.
Explanation:
A nonelectrolyte is a molecular compound that does not consist of ions hence it does not dissociate into ions in solution.
A weak electrolyte is a soluble ionic compound that dissociates only to very small extent into ions in solution.
A strong electrolyte is a soluble ionic compound that dissociates completely into ions when dissolved in water.
Answer:
Fig 3 is a mixture
Explanation:
Fig 1 has just one kind of atoms.
fig 2 shows 2 atoms of the same kind bonded together (compound)
fig 4 shows atoms of 2 different kinds bonded together (compound)
only in fig 3 we see uneven distribution of two kinds of atoms. By definition a mixture contains two or more kind of substances randomly arranged. So fig 3 shows arrangement of mixture
