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 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 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 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.
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.
Is it true to check that an equation is balanced count the number of atoms of each type on each side of the equation?
Pretty much. To make sure an equation is balanced you'll want to make sure there are the same number of each atom on each side of the equation. So: If there are 5 H's that are reactants, make sure there are 5 H's that are 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?
To balance the number of sulfate ions on each side of the equation, a coefficient of 3 should be placed in front of CaSO4. This will give a total of 3 sulfate ions on each side of the equation.
Is the equation 2NO O2 - NO2 balanced why or why not?
2NO + O2 --> NO2 is not balanced. There are two nitrogen atoms on the left and only one on the right. There are four oxygen atoms on the left and only one on the right. The correct balanced equation is 2NO + O2 --> 2NO2.
What number should be placed in front of HF to balance this chemical equation?
To balance the chemical equation HF, you would need to place the coefficient "2" in front of HF. This would give you 2HF on both sides, creating a balanced equation: 2HF = 2HF.
What is wrong with the balanced equation 2Zn solid plus 4HCl aquous yields 2ZnCl2 aquous plus 2H2 gas?
The equation is balanced, but it's not as simple as it can be. The correct equation is: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
How many atoms of hydrogen appear on each side of the equation?
To determine the number of hydrogen atoms on each side of the equation, you would need to balance the equation first. Once the equation is balanced, count the number of hydrogen atoms on both the reactant and product sides to compare. The number of hydrogen atoms should be the same on both sides of the balanced equation.
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.
Which coefficient should be placed in front of PCl3 to balance this equation?
The coefficient that should be placed in front of PCl3 to balance the equation depends on the specific chemical equation you are referring to. Can you please provide the chemical equation?
Is 0N2 0H2 0NH3 balanced?
No, the chemical equation is not balanced. It should be: N2 + 3H2 -> 2NH3.
