(a) sodium hydroxide + ammonium sulfate --> sodium sulfate + ammonium hydroxide
sodium sulfate precipitates in aqueous solutions
(b)<span> niobium(V) sulfate + barium nitrate → Barium sulfate + niobium nitride
both do not precipitate in aqueous solution
</span>(c) strontium bromide + silver nitrate ---> strontium nitrate + silver bromide
both do not precipitate in aqueous solution
<span>Displaced volume:
final volume - initial volume :
38.55 mL - 15.75 mL = 22.8 mL
D = m / V
D = 32.138 / 22.8
D = 1.409 g/mL
hope this helps!

Explanation:
1. Only alcohols forms hydrogen bond between themselves and with other compounds containing an O-H, N-H, or F-H bond, such as water.
2. Alcohols up to 4 carbons are miscible in water because they have hydrogen bonded to oxygen and can form hydrogen bond with water. However, it is not possible for ethers.
3. When comparing ethers and alcohols of similar molecular weights, ethers have lower boiling point than alcohol. This is because of the presence of hydrogen bond in alcohols.
Answer:
Explanation:
Hello there!
In this case, since the equation for the calculation of dilutions is:
Whereas M is the molarity and V the volume, because the final concentration is lower than the initial. Thus, since we are asked to calculate the final volume, we solve for V2 as follows:
Best regards!
The first step is to establish a goal and write it down. This adds commitment and you are declaring your intentions.
The second step is write down your daily plan of action. A plan without action is as useless if you had never written the goal at all.
The third step is to share your goal with someone who will hold you accountable. They can share your victories , failures, and provide encouragement.
The final step is to act on that plan. You must take action now that you have all the tools.
