Answer : The correct option is (c)
Explanation :
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 3 moles of react to give 2 mole of
So, 1 mole of react to give
moles of
Thus, the conversion factor needed to convert the number of moles of to the number of moles of
produced is
Hence, the correct option is (c)
Thus 174 protons would make at most 6 copper atoms. However, it would take 174 extra electrons (29 per atom) and even more neutrons than that to construct neutral copper atoms with stable nuclei.
Answer:
Observe odor, determine pH, determine density, determine boiling point
Explanation:
The correct procedures that would be best to use to determine whether a beaker contains only distilled water would be to observe the odor of the liquid in the beaker, determine the pH of the liquid, determine the density, and then determine the boiling point of the liquid.
<em>Water is generally odorless and has a pH of approximately 7 with a density of 1 kg/m3 and a boiling point of 100 </em><em>. If the liquid in the beaker ticks all these conditions, then it can be established to be only distilled water.</em>
