Can the number of moles of a substance be found by looking at a balanced equation?
yes the number of moles is the the number before the substance for example if the equation is balanced and you want to find H2O and it appears like 3H2O in the equation then their are 3 moles of H2O
How do you find the amount of precipitate in a saturated solution?
first you need to know the number of liters and moles and the equation. you do someting then multiply the liters times the moles. first you need to know the number of liters and moles and the equation. you do someting then multiply the liters times the moles.
What is balanced in chemical equation?
the moles of the reactants and products
How many moles of carbon and hydrogen are there in 5 moles of octane?
Balanced equation. 2C8H18 + 25O2 -> 16CO2 + 18H2O 5.5 moles C8H18 (25 moles O2/2 moles C8H18) = 68.75 moles O2 needed
How many moles of carbon dioxide are produced when 84.4 moles of hexane is burned?
Balanced equation first, 2C6H14 + 19O2 >> 12CO2 + 14H2O 84.4 moles hexane (12 moles CO2/2 moles C6H14) = 506.4 moles of CO2
What information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction?
The information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction is the number appearing immediately before the formula for the reactant in question in the chemical equation. This number is called a "coefficient".
How do you solve this question?
Titration equation can be solved by following the steps below: 1. write a well balanced equation. 2. Calculate number of moles of standard solution that is in the solution. 3. User molar relationship to convert moles of standard solution to that of unknown solution. 4. Find the number of moles of unknown solution.

Use the following balanced equation to answer these question n2h4 plus 2h2o2--n2 plus 4h2o how many moles of h2o are produced from 1.5 moles of n2h4?
N2H4 + 2H2O2 -> N2 + 4H2O 1.5 moles N2H4 (4 mole H2O/1 mole N2H4) = 6.0 moles water produced
What is balanced in chemical equation?
the moles of the reactants and products
How many moles of Cu must react to produce 4 moles of NO?
3Cu + 8HNO3 ----> 3Cu(NO3)2 + 2NO + 4H2O is the equation if it is dilute nitric acid. In concentrated nitric acid the equation is different. So 3 moles of copper produce 2 moles of NO. Therefore it requires 6 moles of copper to produce 4 moles of NO.
Which is the limiting reactant when 3.00 moles of calcium are reacted with 8.00 moles of water in the following equation?
H2o
How many moles of NH3 are produced when 1.4 moles H2 reacts?
Balanced equation. N2 + 3H2 --> 2NH3 1.4 moles H2 (2 moles NH3/3 moles H2) = 0.93 moles NH3 produced =======================
How many moles of carbon and hydrogen are there in 5 moles of octane?
Balanced equation. 2C8H18 + 25O2 -> 16CO2 + 18H2O 5.5 moles C8H18 (25 moles O2/2 moles C8H18) = 68.75 moles O2 needed
How many moles of SO3 will be produced by 1.32moles of O2?
Balanced equation. 2S + 3O2 --> 2SO3 1.32 moles O2 (2 moles SO3/3 moles O2) = 0.880 moles sulfur trioxide produced ========================
