C16H32O2(aq) --> 16CO2(g) + 16H2O(l) ... said its wrong though?
This is because you haven't added any oxygen needed for the combustion, so your equation does'nt balance. Also a solution in water [aq] doesn't burn! 
Try C16H32O2(s) + 23O2(g) --> 16CO2(g) + 16H2O(l)

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Work is being done in which of these situations? All motions are at a constant velocity (including velocity = zero).

tigry1 [53]

Answer:

None of the above

Explanation:

Work is defined as the force that moves an object through a particular distance:

Workdone = force x displacement

At constant velocity, the force on a body is zero because such a body is not accelerating.

Force is a product of mass and acceleration. Acceleration occurs only when velocity changes with time. If no change in velocity, acceleration does not occur. Therefore, no force is being applied.

From all the situations given, the condition is set at constant velocity. At constant velocity, there is no acceleration. This implies that no work is done.

Rank the ions in each set in order of increasing size, and explain your ranking:

Paha777 [63]

Explanation:

Lithium, sodium and potassium are all group 1A elements and when we move down a group then there occurs an increase in atomic size of the elements. As lithium is the smallest and potassium being the largest so, when each of them will lose an electron and obtain a positive charge then size of lithium will further decrease.

Therefore, ions are ranked according to their increase in size as follows.

$Li^{+} < Na^{+} < K^{+}$

When an atom tends to gain electrons then it acquires a negative charge. This means that size of the atom increases.

So, more is the negative charge present on an atom more will be its atomic size. Therefore, correct order of increasing size for $Se^{2-}, Rb^{+}, Br$ is as follows.
