When the equation nacn plus h2so4 equals na2so4 plus hcn is balanced the coefficient of the hydrogen cyanide hcn is?
To balance the equation, you need 2 molecules of HCN on the reactant side. This will give you the balanced equation: NaCN + H2SO4 -> Na2SO4 + 2HCN.
What is the reactant in the equation C8H18 plus O2CO2 plus H20?
The reactants are C8H18 and oxygen.
What is the reactant in 2H2O equals 2H2 plus O2?
There is no limiting reactant in that equation, it's balanced. Four hydrogens on the left, 4 on the right, 2 oxygens on the left, 2 oxygens on the right. If it was 3H2 then it would be oxygen.
What are the reactant in this equation K2SO4 plus Pbl2 PbSO4 plus 2Kl?
K2SO4 + Pbl2 are the reactants.
Is copper sulphate a reactant or a product in the following equation copper sulphate plus sodium hydroxide equals copper hydroxide plus sodium sulphate?
In the balanced equation CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4, copper sulfate (CuSO4) is a reactant. It reacts with sodium hydroxide (NaOH) to form copper hydroxide (Cu(OH)2) and sodium sulphate (Na2SO4).
Equation that can be expressed in the form of the equation y equals ax2 plus bx plus c?
A quadratic equation.
What is the limiting reactant of NaHCO3 plus HCl NaCl plus CO2 plus H2O?
In this reaction, the limiting reactant is whichever reactant is completely consumed first and limits the amount of product that can be formed. To determine the limiting reactant, you would need to compare the stoichiometry of the reactants. The reactant that provides the least amount of product based on the balanced equation is the limiting reactant.
What does the plus sign indicate in a chemical equation?
The plus sign in a chemical equation indicates the presence of more than one reactant or product. It separates individual chemical species on either side of the equation.
What is the equation for -d plus 7 equals 3?
That's the equation.
