Balancing equations and reactions?
think of slightly: for combustions, they continually ensue interior the presence of oxygen. and oxygen continually has tow molecules (O2). the consequence of combustions is likewise continually carbon dioxide and water (offering that there is sufficient capability, which i'm assuming there is by the fact it wasn't stated different clever) In synthesis reactions that 2 aspects are purely mixed. Mg is a plus 2 value, and peroxide is a -2, so which you do not have lots of a difficulty there. Decompositon, you purely wreck it aside. Copper and carbonate. basic. single alternative you could desire to insure that zn is extra lively than H and that's can replace it. If no longer the reaction can wade through. Double alternative. replace the climate. AB + CD ----> advert + CB
Types of chemical reactions/balancing equations?
1) To balace an equation, you have to have the number of the element atoms equal. That means there must be the same number oxygen atoms on both sides, same number of carbon atoms, etc. When there is a coefficient in front of a compound, you have to multiply it to all the exponents througout the compound to get the number of the atoms. 2) An exothermic reaction is when an atom releases energy, usually in the form of either heat or light, and an endothermic reaction is when an atom gains or takes in energy. Exothermic (example): When a light bulb is turned on, it gives off heat and light. Endothermic (example): When you set an ice cube out, it is taking in the air's energy, which results in it melting. Hope this helped!
Yes, but only simple fractions that are not difficult to understand.For example, for the burning of carbon monoxide you write:2CO + O₂ → 2CO₂but you can also write:CO + (1/2)O₂ → CO₂As a general rule, I would suggest that fractions will be accepted if they just render molecules to atoms or multiples of molecules to molecules, but nothing more complicated.So, for 4 Fe + 3O₂ → 2 Fe₂O₃you may write 2 Fe + (3/2)O₂ → Fe₂O₃but not Fe + (3/4)O₂ → (1/2)Fe₂O₃
Balancing chemical equations/reactions?
Hi, I'm working on my chemistry homework where I have to balance equations and sometimes classify the type of reaction. Any help? 1.Complete and balance this decomposition reaction: SF(6) in a gaseous state yields: 2. Write the equation for the complete combustion of hexane: C(6)H(14) + O(2) yields CO(2) + H(2)O Write and balance the equation, if possible, for the following: silver + sulfur --> silver sulfide potassium chloride + silver nitrate --> carbon + oxygen --> carbon monoxide hydrogen + Fe(3)O(4) --> iron + steam (just wondering on this one, is there no reaction since H(2) is lower on the reactivity scale than Fe?) I know this is a lot, but if you can help out on any, I'd really appreciate it. Thanks!
Plz chem help with balancing equation?
27. calcium oxide Ca + O2 ===> CaO 28. don't understand the question. 29. Aluminum chloride 2Al + 6HCl ===> 2AlCl3 + 3H2 30. potassium chloride + iodine 2KI + Cl2 ===> 2KCl + I2 31. Barium sulfate + sodium chloride BaCl2 + Na2SO4 ===> BaSO4 + 2NaCl 32. Silver steel Cu + 2AgNO3 ===> Cu(NO3)2 + Ag 33. Barium sulfate + water Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O 34. Zinc sulfide + ammonium sulfate ZnSO4 + (NH4)2SO4 ===> ZnS + (NH4)2SO4 35. Sodium hydroxide + hydrogen 2Na + 2H2O ===>2NaOH + H2 36. Magnesium sulfate + hydrogen Mg + H2SO4 ===> MgSO4 + H2 37. i will basically assume which you somewhat decide to warmth mercuric oxide. Mercury + oxygen gas. 2HgO + warmth ==> 2Hg + O2
Chemistry balancing help? net ionic equations?
ok so i did a lab where we combined alot of compounds with eachother, some having reactions and some not. The one that had reactions, i have to balance them and make net ionic equations for them. So for example the first one, NiCl2 +NaOH ------> NiOH + NaCl2 (if thats right). how do i balance this???? i didnt pay attention really in class and i have a ton of stuff due monday, i need to balance each compound, and then how do i make a net ionic equation for this?? u will be my hero if u answer
More Help balancing a Chemistry Equation?
I believe thy has asked to balance the equation of the formation of strontium nitride from elemental strontium and atmospheric nitrogen Sr + N2 ---> Sr3N2 3Sr + N2 ---> Sr3N2 2) Iron (III) oxide will react with CO to give CO2 and Iron Fe2O3 + CO ----> Fe + CO2 Fe2O3 + 3CO ----> 2Fe + 3CO2 (on balancing) More Info : Iron (III) oxide is called ferric oxide with formula Fe2O3 Iron (II) Oxide is called ferrous oxide with formula : FeO Iron (II, III) oxide is the mixture of the above iron oxides called ferro-ferric usually represented by Fe3O4 Additional info. for help : If you want to balance equations you can visit : http://www.webqc.org/balance.php To see an example visit: http://www.webqc.org/balance.php?reactio...
(2)HCl + (2)NaOH→ (2)NaCl + (2)H2OH total left = 4, Cl total left = 2, Na total left = 2, O total left = 2H total right = 4, Cl total right = 2, Na total right = 2 O total right = 2first balance the Cl and Na, then hydrogens, then oxygens. always balance the oxygens last.total = 8
Help with Balancing a chemistry equation?
I need to write two equations based on the following information and i also need these formula's to be balanced, can someone whose very smart in chemistry pleeease help. here it goes; 1st one as follows; "Magnesium Nitrate and water are the products of a neutralization reaction" 2nd one as follows; Aluminum Chloride + Magnesium, i need the formula and balanced. Thanks if you can help!
Chemistry Balancing Equation Help (Basic)?
once you decompose NH4NO3(s), you will get N2O and H2O. The NH4+ ion does not choose to run around via himself... like the Mercury dimer. NH4NO3 (s) + warmth ----> N2O(g) + 2H2O(g) CaCl2(s) will ionize becuase this is soluble into ---> Ca 2+ (aq) + 2Cl- (aq) in simple terms such as you wrote it. HTH!
