2Na(s) + 2H2O(l) = 2NaOH(aq) + H2(g)
Answer:
OH−(aq), and H+(aq)
Explanation:
Redox reactions may occur in acidic or basic environments. Usually, if a reaction occurs in an acidic environment, hydrogen ions are shown as being part of the reaction system. For instance, in the reduction of the permanganate ion;
MnO4^-(aq) + 8H^+(aq) +5e-------> Mn^2+(aq) + 4H2O(l)
The appearance of hydrogen ion in the reaction equation implies that the process takes place under acidic reaction conditions.
For reactions that take place under basic conditions, the hydroxide ion is part of the reaction equation.
Hence hydrogen ion and hydroxide ion are included in redox reaction half equations depending on the conditions of the reaction whether acidic or basic.
Answer:
Li is more reactive then Be.
Explanation:
As you go to the farther left and down on the periodic table, the higher that element reactivity is.
The Earth's weather and climate is dependent on the angle at which a specific point is positioned in relation to the sun. Points angled towards the sun will experience higher temperatures, thus turning water to vapor that eventually returns to the ground as rain as it cools in the atmosphere. In points angled away from the sun, this water evaporates slower and returns to the ground as sleet or snow.
Answer:
The answer is Helium.
Explanation:
Scandium's atomic number is 21.
Sulfur's atomic number is 16
Lithium's atomic number is 3
Helium's atomic number is 2.
Therefore, the answer is Helium.
