you have to know the conentrations fo at least two of yourcompaunds or it is not posible to answere this.
This is a physical change, not a chemical one, but you can write anequation. CO2(g) --> CO2(l) However, make sure you write the 2's as subscripts.
Formula, not equation. An equation describes a reaction, not achemical. Lecithin is a mixture of a lot of different chemicals, mostlyphospholipids.
A chemical equation is a written symbolic representation of achemical reaction. The reactant chemical(s) are given on theleft-hand side and the product chemical(s) on the right-hand side.The law of conservation of mass states that no atoms can be createdor destroyed in a chemical reaction, so the...
A chemical equation represents a reaction--a change of something from one state to another. For example, the burning of hydrogen to form water: 2H 2 + O 2 => 2H 2 O A chemical formula represents a compound, such as H 2 O for water. However, muddy water is not a compound. It is water with a...
it must be cleared that while writing a chemical equation... itmust be in symbols of that element then the numbers of the atoms used in the reaction must be equatedto both the sides that is it must be equal to right hand side aswell as left hand side... we need to remember the symbols of thatelement
It means that the reaction is reversible, such as that in the production of ammonia in the haber process
K2HPO4 + NaHCO3 --> K2NaPO4 + H2O + CO2 is the balanced equation for the reaction of dipotassium hydrogenphosphate and sodium bicarbonate. (All numbers should besubscripts). Dipotassium phosphate does not exist. Tripotassium phosphate, K3PO4does, but it's not acidic and therefore does not react with...
Vinegar is acetic acid: CH3COOH Baking soda is sodium bicarbonate: NaHCO3 Mixing the two is simply and acid base reaction. CH3COOH + NaHCO3 ---> CH3COONa + H2CO3 That last product is carbonic acid which quickly decomposes into carbon dioxide and water: H2CO3 ---> H2O + CO2
Pb(NO 3 ) 2 + 2KOH --> Pb(OH)2 + 2KNO3
A chemical equation tells you what substances are reacting, whatsubstances are produced and, in a balanced equation, provides thecoefficients to tell us in what ratio the substances react or areproduced.
2HCl + CaCO3 -> CO2 + H2O + CaCl2 You should probably refer to muriatic acid as hydrochloric acid, asthis is a much more well know name for it, and also the IUPAC name.
Since NaOH is easily water-soluble, complete dissociation willoccur, and you will only have ions. Adding manganese ions (in theform of either manganese chloride or manganese nitrate) will giveyou the net ionic equation Mn+2(aq) + 2OH-(aq) --> Mn(OH)2(s).
Due to the law of conservation of mass and matter, all particlesmust have an equal number on both sides of a chemical equation. Anequal number of atoms of each element involved must be on each sideof the equation.
Law of conservation of mass is satisfied whenbalancing chemical equations. By the way, the conservation of (the kind and number of) elements and charge is also satisfied.
Yes, chemical equations describe chemical reactions. A chemicalequation tells you what substances are reacting, what substancesare produced and, in a balanced equation, provides the coefficientsto tell us in what ratio the substances react or are produced.
Sodium Carbonate is the disodium salt of the carbonate anion.Sodium is a +1 cation while carbonate is a -2 anion. It is a basicsalt when dissolved in water. Sodium carbonate doesn't have aequation itself, but when dissolved in water (deionization), itlooks like this: Na 2 CO3(s) 2 Na + (aq) + (CO3...
The general form is: "Reactants" ----> "Products" Therefore theright hand side of the equation are the products. Any catalysts,conditions, or reaction times may be listed over the arrow.
Balancing a chemical equation can often require a whole-numbercoefficient placed in front of a chemical formula. This upholds theLaw of Conservation of Matter, which says that matter cannot becreated or destroyed. These coefficients must be in the lowestpossible ratio.
Na 2 CO 3 + ZnCl 2 -------> 2NaCl + ZnCO 3

Stoichiometry uses relationships between reactants and/or productsin a chemical reaction to determine desired quantitative data.
The net ionic equation for this process is: Ni(s) + Cu(+2)(aq)--> Ni(+2)(aq) + Cu(s). This is an oxidation-reduction reaction,where nickel is oxidized and copper is reduced.
BaCl2(aq) + Na2CO3(aq) --> 2NaCl(aq) + BaCO3(s). Or, the netionic: Ba(+2)(aq) + CO3(-2)(aq) --> BaCO3(s).
KCl + Ba(SO 4 ) â NR (no reaction) Potassium and chloride don't react, and BaSO 4 does not dissolve. Only the opposite reaction would take place: Sulfate and barium from other sources are precipitating to solid. SO 4 -2 (aq) + Ba 2 + (aq) â BaSO 4(s)
Ca24(aq) + 2HCO-3(aq) ----> CaCO3 + H2O(l) + CO2 (g)
4HCl(g) + O 2 (g) -> 2Cl 2 (g) +2 H 2 O
You use mole ratios for two reasons. One: To balance the number of moles to get the correct answer. Two: To finalize the cancellations of the measurements to get the answer.
A suitable test chemical could be sodium chloride. Sodium chloride(NaCl) is easily water soluble, which means the ions willdissociate from each other. The lead(II) ions will then react withthe chloride ions to produce the insoluble salt lead(II) chloride(PbCl2). Because it's insoluble, you'll get a...
the subscript refers to how many atoms of each element are in the molocule. for instance, H 2 O means two hydrogen molecules and one oxygen molecule.
Study island answer: C 3 H 8 + 5O 2 3CO 2 + 4H 2 O
Both sides of a chemical equation must balance due to the law of"Conservation of Mass" which states that in a reaction no matter iscreated or destroyed. The mass of the reactants must equal the massof the products. Eg. Methane (CH4) combustion (reaction with oxygen) CH4+2O2 = 2H2O+CO2 Reactants ...

The chemical equation for hydrogen to water vapor is not possible as stated. In order for hydrogen to form water in any physical state, it must combine with oxygen. The following are the word equation and the chemical equation for hydrogen and oxygen combining to form water. Hydrogen gas plus...
The substances on the left side of a chemical equation are the reactants . The right hand side substances are the products. i.e. A + B -------> C + D (reactants) (products)
2O means two molecules of oxygen involved in the reaction and O2means two atoms of oxygen which are ready to form a bond after achemical reaction
C6H12O6 + 6O2 = 6CO2 + 6H2O + (Energy) Just add the 6 at the beginning of H20, so it makes Hydrogen 12 and Oxygen 18. Balancing both sides. .
To balance a chemical equation, you can change the coefficients (number of molecules). Remember: You cannot change the subscripts. When we balance an equation we change the number of atoms on one or both sides of the equation by means of simple mathematical calculation. That is, we change the...
Stoichiometery is the use of math in chemistry to determine numerical values for chemical equations, using molecular formulas and molar masses. The stoichiometric ratio for an added reactant (reagent) is the amount required to fully complete the reaction with another reactant, such that there is...
This is because according to the law of conservation of mass mass can neither be created nor destroyed in a chemical reaction. to prove this statement correct a chemical equation should be balanced
2Li+ 2H2O => 2Li(OH) + H2
When a substance melts, like sugar, the chemical structure does not change. It is still sugar. Whether it is crystaline, solid (as in a lollipop), or melted, it still has the same equation - c12 h22 o11.
Sulfuric acid just adds a proton to ammonia to give ammonium: H+ + NH3 -> NH4+ or H2SO4 + NH3 -> NH4+ + HSO4-

Potassium is in group one, so according to solubility rules, it will aways be soluble and therefore a spectator ion. That means that it will not take part in the chemical reaction and in a net equation it would not have to be included. HgCl 2 + K 2 S yields HgS + 2KCl(aquious)
You are doing: Magnesium + Oxygen -> Magnesium Oxide So replace the words with symbols to make the equation more advanced: Mg + O2 -> MgO And to balance it: 2Mg + O2 -> 2MgO
