A hurricane will weaken after making landfall.
Unfortunately, we have not fully solved the 'nitrogen problem'. To do this, we must halve the amount of nitrogen we dump into the environment by mid-century or our ecosystems will face epidemics of toxic tides, lifeless rivers, and dead oceans. And that to do that will require, among other things, almost doubling the efficiency of nitrogen use on the world’s farms.
Answer:
29 L.
Explanation:
Hello!
In this case, considering that we are performing a conversion by which the time should be cancelled out to obtain liters, we first need to convert the seconds on bottom to hours and then the volume on top to liters, just a shown down below:

Which turns out 29 L with 2 significant figures.
Best regards!
Answer : Carbon tetrachloride,
will show the greatest freezing point lowering.
Explanation :
For non-electrolyte solution, the formula used for lowering in freezing point is,

where,
= lowering in freezing point
= molal depression constant
m = molality
As per question, the molality is same for all the non-electrolyte solution. So, the lowering in freezing point is depend on the
only.
That means the higher the value of
, the higher will be the freezing point lowering.
From the given non-electrolyte solutions, the value of
of carbon tetrachloride is higher than the other solutions.
Therefore, Carbon tetrachloride,
will show the greatest freezing point lowering.
