The answer is (3) 48.0 g. The gram formula mass means that the mass of one mol compound. So the mass of 1.0 mol of this compound is equal to the gram formula mass 48 g.

Answer:
A chemical change occurred, so even if Cash heats it, the white solid will remain.
Explanation:
- A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A physical change occurred, so even if Cash heats it, the white solid will remain.
- A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A chemical change occurred, so even if Cash heats it, the white solid will remain.
<em>The correct answer would be that a chemical change occurred, so even if Cash heats it, the white solid will remain.</em>
Chemical changes occur when atoms in a substance or mixture of substances are rearranged, leading to the formation of new substances.
<u>In this case, the mixture of the two clear liquids led to the formation of gas in form of bubbles and a white solid forms that settle at the bottom. The formation of these 2 substances from the mixture of the two clear liquid is an indication of chemical reaction/changes. Hence, even if cash heats the resulting mixture, the white solids will likely remain.</u>
The reaction between sodium hydroxide and ammonium sulfate generates ammonia gas along with water and aqueous sodium sulfate. The reaction can be shown as follows:
2NaOH(aq) + (NH4)2SO4(aq) → 2NH3(g) + Na2SO4(aq) + 2H2O(l)
The reaction can be further simplified to give a net ionic equation as:
2Na+(aq) + 2OH-(aq) + 2NH4+(aq) + SO42-(aq) →
2NH3(g) + 2Na+(aq) + SO42-(aq) + 2H2O(l)
Net ionic:
OH-(aq) + NH4+(aq) ↔ NH3(g) + H2O(l)
