When chemicals react, atoms cannot be either created or destroyed. So there must be the same number of each type of atom on the reactants side of a chemical equation as there are on the products side. A symbol equation is a shorthand way of describing a chemical reaction. It shows the ...
cWrite a balanced equation for the reaction. As 1 mole of propane produces 3 moles of carbon dioxide, there must be 3 moles of carbon atoms in one mole ofpropane. C3Hx + 5O2 --> 3CO2 + yH2O The 5 moles of oxygen molecules are used to react with both the carbon a...

Consider the combustion of propane (C_3H_8) in the presence of oxygen: C_3H_8 + 5O_2 to 3CO_2 + 4H_2O. How many grams of O_2 are required to react completely with 3 moles of propane? Using the balanced reaction equation for the complete combustion of propan...
The Cl ratio is 1:2, which means that we need to increase (double) the number of Cl molecules on the reactant side. To do this, we place a coefficient of 2 in front of HCl, so the new equation looks like this:Zn + _2_ HCl <---> ZnCl2 + ___ H2 Now, we just have to ...
Volume is a dependent variable and its dependence on mole numbers is taken into account by solving a nonlinear equation (the volume balance equation) for pressure at each iteration level. By analyzing the block structure of the Hessian matrix in the constrained minimization of the Helmholtz free ...
