Answer:
There would be 25 moles
Explanation:
This is the equation for water (synthesis):
2H₂ + O₂ → 2H₂O
Since there are 25 moles of water, the moles of hydrogen gas will have 25 moles.
Answer:
B) A Mg atom donates two electrons to a Cl atom.
Explanation:
During the formation of magnesium chloride, magnesium loses two electrons to form a stable cation. One chlorine atom requires one electron to form a stable anion. Hence, two chlorine atoms combine with one magnesium by accepting one electron each.
Answer:
Your Answer is C (all chemical reactions occur at different rates)
Explanation:
Where’s the chart and scientists?
The conclusion that was drawn from the results of the
gold foil experiment is that electrons in an atom are located in specific
