Answer:
FALSE
Explanation:
The under-water deep ocean currents that are generated due to the differences in the water density are generally termed as the thermohaline circulation. It is mainly controlled by the two factors namely the temperature and the salinity. The word 'thermohaline' is directly derived from the temperature (thermo) and salinity (haline).
This thermohaline circulation is considered as the oceanic conveyor belt that allows the water to move under the surface of water at certain depths from the equator to the poles and back from the poles to the equator.
Thus, it is directly associated with the density of the water. It has no relation with the wind.
Hence, the above statement is False.
When given percents for an empirical formula problem, first consider all the percents as grams.
58.82% carbon —> 58.82 g carbon
27.45% nitrogen —> 27.45 g nitrogen
13.73% hydrogen —> 13.73 g hydrogen
Then convert the grams of all the elements to moles, based on their molar masses.
Carbon - 58.82 g / 12.01 g/mol = 4.898 mol carbon
Nitrogen - 27.45 g / 14.01 g/mol = 1.959 mol nitrogen
Hydrogen - 13.73 g / 1.008 g/mol = 13.62 mol hydrogen
Then divide all of the mole numbers by the smallest number of moles, which is in this case, the 1.959 mol of nitrogen.
Carbon - 4.898 / 1.959 = 2.5
Nitrogen - 1.959 / 1.959 = 1
Hydrogen - 13.62 / 1.959 = 7
You want whole numbers for all of your mole numbers, so multiply all of them by 2, since 2.5 isn’t a whole number.
Final answer: C5N2H14

Given what we know, we can confirm that if while setting up a beaker you notice that the stirring is erratic and unstable, you should immediately turn off the stirring mechanism.
<h3>Why turn off the stirring mechanism?</h3>
- The beaker is boiling a substance, making it very dangerous.
- Unstable and erratic stirring can cause spilling or even a broken beaker.
- The best course of action is to disable the stirring until the problem is fixed.
- This will ensure the safety of everyone involved.
Therefore, we can confirm that in order to ensure the safety of all participants, if while setting up a beaker you notice that the stirring is erratic and unstable, you should immediately turn off the stirring mechanism.
