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 chemists use balanced equations?
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.
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
What is the name of the chemical law on which problems 6 and 7 are based?
We cannot help you - as we don't know what problems are detailed in your text book !
What problems coud occur while trying to collect gas from chemical reactions?
The most important is the loss of the gas.
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.
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.
Why is it essential to use balance equations in solving stoichiometric problems?
It is essential to use balanced equations when solving stoichiometric problems because each kind of atom has to be the same on both sides of the equation. The chemical reactions that take place are molar ratios.
How do you solve Hess's law problems?
To solve Hess's law problems, first write out the chemical equations for all reactions involved. Then calculate the enthalpy change for each reaction. Finally, add or subtract the enthalpy changes to obtain the overall enthalpy change for the desired reaction.

What can cause strong shaking of my 98 acura at 60 mph or above?
I would get the tires balanced first. If still having problems then check front axel shafts. I would get the tires balanced first. If still having problems then check front axel shafts.
What does it mean if an equation is simplified to 0 0 do all problems have exactly one solution?
An equation that is simplified to 0 0 is called a perfect equation. It usually have exactly one solution.
Do I need to have the wheels balanced after installing new rim and tire package?
You Should take it to have the wheels balanced at a mechanic to ensure that you care works properly. This will ensure that you do not have problems down the road.
