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
2Na + 2H2O -------> 2NaOH + H2
It is impossible to balance AL CI H2 because it is an incomplete equation. There are products missing from this chemical equation. If your query was how do you balance 2 HCI + 2AL then the answer would be 2 HC1 + 2 AL = 2 ALCI + H2.
The balanced chemical equation for H2 plus Br2 produces 2 HBr.
The balanced equation for Na + HNO3 is: 2Na + 2HNO3 -> 2NaNO3 + H2
The chemical symbol (not equation) of hydrogen is H; the diatomic molecule is H2.
The balanced chemical equation is 2HBr + H2 + Br2 + N2O → N2 + O2 + HBr + H2 + Br2. The equation provided in your question doesn't appear to balance correctly, so I attempted to balance it based on the chemical species presented. It's essential to ensure that the number of atoms of each element is the same on both sides of the equation.
2Na + 2H2O -> H2 + 2NaOH
2Na + 2H2O -------> 2NaOH + H2
This simple equation is: 2H2 + O2 = 2H2O
The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
The balanced chemical equation for the reaction of sodium with water is: 2Na + 2H2O -> 2NaOH + H2
The chemical equation is not balanced. It should be balanced as follows: H2 + Cl2 → 2HCl
It is impossible to balance AL CI H2 because it is an incomplete equation. There are products missing from this chemical equation. If your query was how do you balance 2 HCI + 2AL then the answer would be 2 HC1 + 2 AL = 2 ALCI + H2.
Balanced :2 K + 2 H2O ----> 2 KOH + H2
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
The balanced chemical equation for H2 plus Br2 produces 2 HBr.
To balance the equation Zn + HCl → ZnCl2 + H2, you need to ensure that the number of each type of atom is the same on both sides of the equation. To balance it, you would need to write it as Zn + 2HCl → ZnCl2 + H2. This equation balances the number of zinc, hydrogen, and chlorine atoms on both sides.
