Ag2S3 + H2-------> Ag + H2S ( Write Out) Ag2S3 + 3H2-------> 2Ag + 3H2S ( Balanced) Reaction= single replacment
The equation as given can not be balanced, because it is incomplete: When hydrogen peroxide decomposes to produce water, it also produces oxygen. A proper, balanced equation for the reaction is 2 H2O2 -> 2 H2O + O2.
2Na(s) + 2H2O(l) ---> 2NaOH (aq) + H2(g)
The equation is H2 + F2 -> 2 HF.
When sodium and water react, they will produce aqueous sodium hydroxide and hydrogen gas. Here's the balanced equation for that reaction: 2Na + 2H2O --> 2NaOH + H2 This reaction is violently exothermic and should be done under very safe and controlled conditions. The hydrogen gas will likely ignite, which itself is a different reaction: 2H2 + O2 --> 2H2O
2Na + Cl2 -> 2NaCl
3h2 + n2 = 2nh3
The equation as given can not be balanced, because it is incomplete: When hydrogen peroxide decomposes to produce water, it also produces oxygen. A proper, balanced equation for the reaction is 2 H2O2 -> 2 H2O + O2.
The product is water:2 H2 + O2 = 2 H2O
2Na(s) + 2H2O(l) ---> 2NaOH (aq) + H2(g)
The equation is H2 + F2 -> 2 HF.
Do not try this! 2Na +2HCl --> 2NaCl + H2 The last 2 should be a subscript.
This is not a correct question.
N2 + 3H2 -> 2NH3 The stoichiometric equation (or balanced equation) for the formation of ammonia from this we can read off the mole ratio between hydrogen and ammonia; 3M H2 needed to produce 2M NH3 times each by 9 (so the ratio remains the same and 18M NH3 is formed) 27M H2 needed to produce 18M NH3
When sodium and water react, they will produce aqueous sodium hydroxide and hydrogen gas. Here's the balanced equation for that reaction: 2Na + 2H2O --> 2NaOH + H2 This reaction is violently exothermic and should be done under very safe and controlled conditions. The hydrogen gas will likely ignite, which itself is a different reaction: 2H2 + O2 --> 2H2O
No. The amount of hydrogen produced is dependent on the amount of hydrogen in the reactants. Refer to the following examples. Notice that each equation is balanced so that there are the same numbers of each element on both sides of the equation. 2Na + 2H2O --> 2NaOH + H2 2Al + 3H2O(g) --> Al2O3 + 3H2 2H2O + electricity --> 2H2 + O2
2Na + Cl2 -> 2NaCl
When balancing a chemical equation the reactants need to be balanced with the non-reactants. If you don't the formula will be produce negative results and you'll get the wrong answer.
