First, we can see that the output is a salt and water which means that the reactants were an acid and a base. Since the given reactant is a base, thus, NH4OH is excluded as it is also a base.
Now, examining the outputs of the reactions, we will find that they are composed mainly of sodium, hydrogen, oxygen and carbon. This excludes H3PO4 as it contains phosphorus.
The last step is to compare between the number of moles of each element in the output with those in the input. The output has 1 sodium mole, 2 carbon moles, 5 hydrogen moles and 3 oxygen moles.
The given input (NaOH) has 1 sodium, 1 oxygen and 1 hydrogen moles. Therefore, the other input (reactant) should have 2 carbon, 4 hydrogen and 2 oxygen moles.
Based on this, the right solution is CH3COOH.
Answer:
<u><em>neurons</em></u>
Explanation:
The long-axoned cells, called principal neurons, transmit information over long distances from one brain region to another (Sheperd,1979). Principal neurons provide the pathways of communication within the nervous system.
Weeks = 6 x 4 = 24
Mass leak rate of freon = 41.60 g/week
Mass leak rate of fluorine
Fluorine mass in Freon
= —————————————- X leak rate
M.M. Of Freon
19 x 3
——— X 41.60 = 20.010 gm/week
118.5
Total leaked in 6 months
= 24 x 20.010 = 480.24 gm = 0.480 Kg
the 3rd one is the answer
