Balance this chemical equation?
okay so you know the products, write them down in a chemical equation and balance it. x + x ----> CaSO4 + CO2 You know the reactants as well, they're in the questions. sulfur dioxide = SO2 and calcium carbonate = CaCO3, and oxygen (in air oxygen is O2) if you have time just look up this names on wikipedia it tells you the molecular formula. Now just write the equation, then balance: SO2 + CaCO3 + O2 -----> CaSO4 + CO2 in the right side you have 1 S = left in the right side you have 7O, left =6 1Ca = right 1C = right, so play around until you balance the equation. 2 SO2 + 2 CaCO3+ O2 -----> 2 CaSO4 + 2 CO2 Now count how many atoms of each type on each side.... they match, equation is balanced. As you can see, the mol ratio is 2SO2 for every 2CaSO4, so for every 2mol of one, you need 2 mol the other = a 2:2 ratio = 1:1 ratio. Ten points, thanks.
How do u balance this chemical equation?
with combustion reactions, think "CHO" so first balance the carbons C2H7OH + O2 --> 2CO2 + H2O next hydrogens C2H7OH + O2 --> 2CO2 + 4H2O then oxygen C2H7OH + (7/2)O2 --> 2CO2 + 4H2O multiply everything by 2 to get a whole number for oxygen 2C2H7OH + 7 O2 --> 4CO2 + 8H2O Hope that helped edit: true, C2H7OH is a highly improbable compound because oxygen will not form 4 bonds. Thus, the compound is probably either ethanol (C2H5OH) or propanol (C3H7OH) Balance the same way "CHO" for either.
How do i balance this chemical equation?
its very simple 2KMnO4 + 5KNO2 + 3H2SO4 = 2MnSO4 + 3H2O + 5KNO3 + K2SO4
How do you balance this chemical equation? H2O2--> H2O+O2?
H2O2 yields H2O + O2 2H2O2 yields H20 + O2 2H2O2 yields 2H20 + O2
Balance this chemical equation...?
well, we have two hydrogens... that's balanced now, let's look at the carbons... 2 on the left, one on the right meaning that now we have 2CO2 so then we have five oxygens on the right, and 2 on the left so the left double oxygen gets multiplied by 5/2 and to make sure that we don't have any fractions we multiply everything by 2 so 2C2H2 + 5O2 --- 4CO2 + 2H2O
How do I balance this chemical equation?
ok...so ur given c2h5oh + oxygen which is always represents as O2 since its a diatomic species. Acetic acid is always represented as CH3COOH and water is H20 So ur balanced equation is... C2H5OH + O2 -> CH3OOH + H2O There's no set method..u would have to memorize. That or use wikipedia. It usually tell u the chemical break down
How do i balance this chemical equation?
Paraffin wax is actually a mixture of hydrocarbons. If we assume one of the hydrocarbons compounds has the formula C25H52, write a balanced equation to represent the burning reaction in this lab. This is talking about a burning/melting candle. Products are supposed to be carbon dioxide and water vapor or CO2 and H20
How do I balance this chemical equation: MnO4- + H2O2 + H+ = Mn++ + H2O + O2?
Manan,As you can see that the reaction is a redox reaction and we cannot balance the equation just by the hit and trial method. So in order to give a solution to your problem , I am going to balance the reactants and products by using HALF OXIDATION/REDUCTION REACTION.Just look up to what i do :)As you can see the reaction is almost balanced and we just need to balance the number of oxygen atoms and hydrogen atoms.And the final equation will be:Hope that you find this useful!Goodluck!
How do you balance this chemical equation? C7 H17 + O2 = CO2 +H2O?
Are you sure you did not make a typo? A Hydrocarbon with the formula C7H17 would be very hard to find. Usually, the number of Hydrogens in a ["normal"] Hydrocarbon can be determined by doubling the number of carbons and adding two. In the case we have something that looks like Heptane (7 carbons), so I would expect there to be 16 Hydrogens (7*2 + 2). If you align all the carbons in a row and single bond them to eachother to allow for the maxmium number of C-H bonds, where would you place the 17th Hydrogen atom? If you did mean C7H17, then the balanced reaction would be, 4 C7H17 + 45 O2 = 28 CO2 + 34 H2O However, if you did indeed mean Heptane (C7H16), the balanced reaction would be, C7H16 + 11 O2 = 7 CO2 + 8 H2O
