Answer:
In a voltaic cell (one that happens spontaneously), electrons flow from a negative electrode to a positive electrode (anode cathode). The reaction that happens is a redox reaction where the anode is oxidized (goes from a solid to an ion) and the cathode is reduced (going from an ion to a solid).
Explanation:
Yes your answer is correct the answer is 1.26
solution is moles=mass/molar mass =98.3/78=1.26

Answer:
The answer to your question is 14.3 %
Explanation:
Data
volume of ethanol = 50 ml
volume of water = 300 ml
volume percent = ?
Formula
Percent by volume = (volume of solute/volume of solution) x 100
Volume of solute = 50 ml
volume of solution = 300 + 50 = 350
Substitution
Percent by volume = (50/350) x 100
Simplification and result
Percent by volume = 14.3 %
Explanation:
Neon is an element that has 10 electrons, 10 protons, and most of the time has 10 neutrons in each neon atom. Nitrogen is an element that has 7 electrons, 7 protons, and most often has 7 neutrons in each nitrogen atom. So the Bohr model of a neon atom would be slightly larger than a nitrogen atom.
