2Na + 2H2O -------> 2NaOH + H2
This reaction is:2 Li + 2 H2O = 2 LiOH + H2
The reaction of Na (sodium) with H2O (water) produces NaOH (sodium hydroxide) and H2 (hydrogen gas). So, the equation would be 2Na + 2H2O → 2NaOH + H2.
First off, you decide the product (becomes easier after a while of doing chemistry). The product is H2O (water). O2+H2=>H2O, but this is not stochiometrically balanced, so you have to change the amount of H2O's on the right side of equation and then to balance the amount of hydrogens. If you add a 2 in front of both, you get O2 + 2H2 => 2H2O
C2H5MgBr + H2 = C2H6 + MgBr2
It's a chemical reaction.
The reaction between Li and H2O produces lithium hydroxide (LiOH) and hydrogen gas (H2). The balanced chemical equation for this reaction is 2Li + 2H2O -> 2LiOH + H2.
lithium, hydrogen, oxygen
2Na + 2H2O -> H2 + 2NaOH
2Na + 2H2O -------> 2NaOH + H2
LiOH (Apex 2021)
This reaction is:2 Li + 2 H2O = 2 LiOH + H2
This simple equation is: 2H2 + O2 = 2H2O
Balanced :2 K + 2 H2O ----> 2 KOH + H2
k+h2o>koh+h2
HCl + NaOH = H2O + NaCl is already balanced.
H2 - hydrogen.
