A solution.
Mass-mass problems can be solved in various ways. You should start by writing a balanced equation for chemical reaction involved and eventually change the mass into moles which will facilitate the comparison and allow you to calculate the number of moles required.

For example, if you have the formula C3H6 + 9/2O2 --> 3CO2 + 3H2O, then usually it's a reduced balanced equation to find the (delta)H (standard molar enthalpie) of a molecule, which in this case would be for the C3H6. To find the original balanced equation, just multiply everything by 2 (since the denominator of 9/2 is 2). It should be C3H6 + 9/2O2 --> 3CO2 + 3H2O to 2C3H6 + 9O2 --> 6CO2 + 6H2O. I hope this helps
A number sentence has a letter as its solution while a number model has the solution. I remember this by thinking of a number model as a model of what the full equation should be and a number sentence being the opposite of that.

A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
A balanced chemical equation is when both the products and the reactants are balanced, or have the same number of atoms on each side of the equation. For example: 2H20 --> 2H2 + O2 This means there are 2 water molecules as the reactants (before reaction) and 4 hydrogen and 2 oxygen atoms as the products (after reaction). Technically the equation wouldn't work in real life if it weren't correctly balanced.
A balanced equation is that equation which obeys the law of conservation of mass.(Added: also the law of conservation of (the kind of) elements should be obeyed).In such an equation the number of atoms for each elementin the reaction and the net or overall charge is same for the reactants and products.

No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.

H2 + F2 ____HF Answer: 2 (APEX)
To correctly determine the balanced chemical equation, one must make sure that the products are appropriately relating to the reactants and make sure that the equation is balanced with the lowest coefficients. That should help.
Be + 2 HCl -> BeCl2 + H2, in which the second and third instances of the number 2 should be subscripts when that font is available.

Mass number and atomic (/proton) number. Electric charge should also be preserved, although this is often accounted for by the atomic number, and electrons (beta-minus particles) are often assigned an atomic number of -1 (and a mass number of 0) for this purpose.
This is a Chemistry symbol. It is used in a balanced symbol equation and represents 6 carbon dioxide molecules. It is normally written as just CO2. But in this case, it should be part of a balanced symbol equation.
