Mass mass problems?
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.
Where should addition signs be placed between digits of the number 987654321 to get a total of 90?

What is 9/2o2?
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
What is the difference between a number sentence and a number model?
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.

What is a balanced chemical equation . why should chemical be balanced?
A balanced chemical equation has correct placed coefficients and a representative chemical equation need these coefficients.
What is a balanced chemical equation why should the chemical equation be balanced?
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.
What is the equations is 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.
What number should be placed in front of CaSO4 to give the same total number of sulfate ions on each side of the equation?
3
Is the equation C3H6 plus O2 yields CO2 plus H20 balanced?
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.
What is a balancing equations of chemical reactions?
coefficients
What number should be placed in front of HF to balance this chemical equation?
H2 + F2 ____HF Answer: 2 (APEX)
How do you use chemical equation in a sentence?
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.
What is the balanced equation fo HCl plus Be?
Be + 2 HCl -> BeCl2 + H2, in which the second and third instances of the number 2 should be subscripts when that font is available.
Which coefficient should be placed in front of PCl3 to balance this equation?
4
What two items must be balanced to achieve a balanced equation for radioactive decay?
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.
What does 6CO2 stand for?
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.
