Why must a chemical equation be balanced to solve stoichiometry problems?
Because chemical reactions take place in molar ratios. The number of moles of each kind of atom has to be the same on both sides of the equation.
How do you solve this partial pressure stoichiometry problem?
Well, first you start with a problem . . .
How many kg of oxygen are consumed when sufficient ammonia NH3 is catalytically oxidized to produce nitric acid HNO3 and 402 kg of water?
You need to write a balanced reaction and then use stoichiometry to solve this problem.First write a balanced reaction. The reactants are O2 and NH3 and the products are HNO3 and H2O. For step-by-step instructions on how to balance a reaction, see the Related Questions link to the left.Then use stoichiometry to solve the problem. See the Related Questions to the left for step by step instructions on how to do that! And don't forget to convert the 402 kg of water into moles!
How many milliliters of 0.248M HCl are needed to react with 1.36 grams of zinc to produce hydrogen?
First, write a balanced equation for this reaction. The reactants are HCl and Zn and the products are ZnCl2(aq), and H2(g). For how to write a balanced equation, see the Related Questions to the left. Then, convert the grams of Zn into moles of Zn. To do that, see the Related Questions to the left. Then use stoichiometry to determine how many moles of HCl are necessary to react with that number of moles of Zn. See the Related Questions to the left for how to solve stoichiometry problems. Finally, determine how many milliliters of solution you need to get that many moles of HCl. To do that, use this equation: number of moles = number of liters * molarity
How do you solve stoichiometry?
You don't solve stoichiometry. The questions and answers that arise in stoichiometry are merely manipulations of permanent relationships between things (e.g. there are approximately 70.9 grams in one mole of chlorine gas). The conversions needed to report an answer of a stoichiometric problem are the part that take work to overcome mentally. One has to evaluate the units that a value starts with and the units the final answer requires and think about what conversions are needed in between.

How do you find a problem number in a equation?
You solve the equation.
How many grams of oxygen are produced when 11.5 grams NO2 is formed?
You can't answer this question unless you know the the NO2 was formed FROM. You need to write the balanced reaction for the reaction and then use stoichiometry to solve for the amount of oxygen produce.See the Related Questions to the left for how to write a balanced reaction and how to use stoichiometry to solve this type of problem.
In a math problem what is parenthesis?
Parentheses is when you are doing an equation, and you solve the problem.
What do you do before you solve a math equation?
State the problem
Which equation would you use to solve the following word problem?
There was no word problem, so it would be a null equation.
