In terms of Chemistry, such equation which obeys the law of conservation of mass are balanced equations since the mass is the same on both the reactants and the product side.
In simple words the no. of atoms on both sides are the same making the sum of the atomic masses the same too. Like in the equation:
CH4 + 2O2 --------------------> CO2 + 2H2O
notice that there is only one carbon on both sides, 4 hydrogen atoms and 4 oxygen atoms on both sides. If we sum their atomic masses it will be equal to 80 on both the reactant and the product side satisfying the "Law of Conservation of Mass" which says the initial and final weight of the system remains the same.
No, the chemical equation is not balanced. The correct balanced equation is 2SO2 + O2 → 2SO3.
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
No, the equation is not balanced. The balanced equation is 2CaSO3 → CaO + SO2 + O2.
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.
Balanced Chemical equation
Its NOT a balanced Equation ,but a FORMULA. Al2(SO4)3 NB A balanced equation is for two or more reacting substances and their respective products.
The balanced equation for the combustion of magnesium is 2Mg + O2 -> 2MgO.
Proteins have a very complicate chemical formula but not a "balanced chemical equation".
To determine if an equation is balanced, compare the number of each type of atom on the reactant side to the product side. Make sure there is an equal number of each type of atom on both sides of the equation. If the number of atoms is balanced, the equation is balanced.
The balanced equation for lithium carbonate is Li2CO3.
The balanced equation for caesium and chlorine is 2Cs + Cl2 -> 2CsCl.
CaCl2 + N2 --> ? They will not react with each other, so there is NO (balanced) equation at all.
