N2 + 3H2 -> 2NH3
3 moles hydrogen gas. You should know that because of the formula of ammonia.
The chemical equation is:2 NaHCO3---------------------Na2O + 2 CO2 + H2O
the balanced equation is N2 + 3H2 = 2NH3
2Na + 2H2O -> 2NaOH + H2
Co + 2h2 -> ch3oh
2 H2O2 → 2 H2O + O2 Check out Wikipedia's entry on Hydrogen Peroxide
No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.No, the equation is not balanced. On the left side there is no hydrogen (H), on the right side there is.
Balanced:2 HI ----> H2 + I2
H2 + Cl2 --------> 2HCl
No equation, it is not a chemical reaction.
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
balanced equation:- AgNO3(aq) + HBr(aq) ----> AgBr(s) + HNO3(aq)
Balanced:H2 + I2 ----> 2 HI
Cl2 + 2H = 2HCl
The balanced symbol equation for copper II oxide reacting with hydrogen is Cu + H2O. This reaction will create copper and water as a result.
Note, hydrogen chloride is usually known as hydrochloric acid. The equation is extremely simple. H2 + Cl2 = 2HCl.
Make sure that the number of atoms on the left side of the equation is the same as the number of atoms on the right side.For example: -H + O2 --> H2O This is not a balanced equation because there is more oxygen and less hydrogen on the left side of the equation then is needed on the right side.4H + O2 --> 2H2O This equation is balanced because there is 4 hydrogen atoms and 2 oxygen atoms on both sides of the equation.
Sodium hydroxide does not react with hydrogen gas.
