A chemical equation should be balanced so as to satisfy the requirements of the law of conservation of mass, as no matter is destroyed or created during a chemical reaction. The two popular methods of balancing are the hit and trial method and parti..
Balancing of Chemical Equations
If the number of atoms of an element on both sides of a chemical reaction is equal, then the equation is said to be balanced..
How to Balance a Chemical EquationDescription: This video discusses the proper way to balance a chemical equation. Content Area: Physical Science/Chemistry Instructional Objective: After viewing this video, the viewer will be able to properly use the steps described to balance an equation. They will also be able to indicate how the equation abides by the law of conservation of mass. Learner Description: This video is targeted at middle school or high school physical science and chemistry students, although at a general level, college students taking an introductory lab science could also benefit from viewing.

Balancing Chemical EquationsStudent made video about how to balance chemical equations.
Question : well i am not that good at writing a chemical equation nor balancing if someone could explain step by step how to start it and being balanced:
1. solid lead (II) sulfide reacts with aqueous hydrochloric acid to form solid lead(II) chloride and dihydrogen sulfide gas.
2. gaseous carbon monoxide reacts with hydrogen gas to form gaseous methane (CH4) and liquid water.
3.solid iron (III) oxide reacts with hydrogen gas to form solid iron and liquid water.
4. gaseous ammonia (NH3) reacts with gase..
Answer : The balanced chemical equations are: 1. PbS(s) + 2 HCl(aq) = PbCl2(s) + H2S(g) 2. CO(g) + 3 H2(g) = CH4(g) + H2O(l) 3. Fe2O3(s) + 3 H2(g) = 2 Fe(s) + 3 H2O(l) 4. 4 NH3(g) + 5 O2(g) = 4 NO(g) + 6 H2O(g)

Question : tell me step by step how you balance the following equations:
1.FeS + HCI --> FeCI2 + H2S
2. Na+ F2 --> NaF
3. HgO --> Hg + O2
i also need the type of reaction for each
Answer : 1. FeS + 2HCI --> FeCI2 + H2S double displacement reaction 2. 2Na+ F2 --> 2NaF synthesis/addition reaction 3. HgO --> Hg + O2 decomposition reaction (this is also a redox reaction) balancing chemical equations is supposed to be easy. Just look for which elements are present in different amounts on either side of the equation and don't touch the ones that appear with the same amount on each side.
