Chemical Equations

The chemical equation for the reaction between sodium hydrogen carbonate (NaHCO3) and limewater (Ca(OH)2) is:

NaHCO3 + Ca(OH)2 → CaCO3 + NaOH + H2O

This reaction produces calcium carbonate (CaCO3), sodium hydroxide (NaOH), and water (H2O).

The chemical equation for the reaction of sulfur and oxygen to form sulfur trioxide is:

2S + 3O2 -> 2SO3

The chemical equation for the reaction when copper is added to aluminum sulfate is:

3Cu + 2Al2(SO4)3 -> 3CuSO4 + 2Al

2SiO2+2C-->Si2+4CO

NH4NO3(s) + H2O(l)--> NH4OH(aq) + HNO3(aq) --> NH4+(aq) + NO3-(aq) + H2O(l)

The intermediate step (with ammonium hydroxide and nitric acid) doesn't really happen, it pretty much goes directly into the ion states. But that is how it would be rearranged for product formation.

1. ( S(s) + O_2(g) → SO_2(g) )
2. ( 2S(s) + 3O_2(g) → 2SO_3(g) )

aluminum bromide = AlBr3

the reason why there is 3 Br atoms is that aluminum is in group 3

chlorine gas exists as a diatomic Cl2 molecule

AlBr3 + Cl2 <------> AlCl3 + Br2

this type of reaction is a subsitiution reaction where chlorine and bromine ate both group 7 gas's and are interchangable

to balance this you'll notice that we lose 2 Br atoms, but have 3 at the start. This can look a bit confusing, so we need a number that both 3 and 2 go into to balance the Br atoms

These both go into 6 so if we use 2AlBr3 that gives us 6 Br on the left hand side and if we generate 3 Br2 on the right hand side we have the bromines balanced

now we've balanced the bromines, you noticed that we unbalanced the Al, so, to balance them again we need to form 2 AlCl3 on the right hand side and the Al is balanced

finally, by balancing the Al we unbalanced the Cl

there are 6 Cl on the right hand side but only 2 on the left hand side, so if we use 3 Cl2 on the left hand side then we have balanced the Cl's

your complete equation looks like this;

2AlBr3 + 3Cl2 <------> 2AlCl3 + 3Br2

The chemical equation for the reaction between stomach acid (hydrochloric acid, HCl) and calcium carbonate (CaCO3) is:

CaCO3(s) + 2HCl(aq) -> CaCl2(aq) + CO2(g) + H2O(l)

Al(s) + 3CuF(aq) -> AlF3 + 3Cu(s) Assuming it's Copper (I) Fluoride 2Al(s) + 3CuF2(aq) -> 2AlF3 + 3Cu(s) Assuming it's Copper (II) Fluoride (s): solid phase (aq): aqueous (dissolved) phase

First we need to determine whether this is a combination, combustion, or decomposition reaction.

It's classified as a combination.

Next we need to determine the correct formulas for the reactants.

These would be Al(s) and Br2(l)

Next, we need to identify the product of this reaction, which would be AlBr3

Lastly, we need to balance the equation.

Your final answer will be:
2Al(s) + 3Br2(l) --> 2AlBr3(s)

Pb(NO3)2(aq) + 2NaI(aq) → PbI2(s) + 2NaNO3(aq) Aqueous lead II nitrate reacts with aqueous sodium iodide to form solid lead II iodide precipitate and aqueous sodium nitrate.

The chemical equation for hydrated copper sulfate is CuSO4 • 5H2O. This indicates that each copper sulfate molecule is associated with 5 water molecules in its crystal structure. When heated, these water molecules are driven off, leaving anhydrous copper sulfate (CuSO4).

The chemical equation for sulfate (or sulphate) is SO42-

Oxygen exists as O2 in its diatomic form in nature. In chemical reactions, oxygen is typically found as a diatomic molecule because it is more stable that way. Writing it as O2 in a chemical equation accurately represents how oxygen exists and behaves in reactions.

The chemical equation for the formation of table salt from sodium and chlorine is:

2 Na + Cl2 -> 2 NaCl

The reaction between phenol and calcium hydroxide results in the formation of calcium phenolate and water. The chemical equation for this reaction is:

C6H5OH (phenol) + Ca(OH)2 (calcium hydroxide) → Ca(C6H5O)2 (calcium phenolate) + H2O (water)

An organic acid with the chemical formula CH3CH (OH). COOH. Lactic acid is a product of anaerobic glycolysisLactic acid system An anaerobic energy system in which ATP is manufactured from the breakdown of glucose to pyruvic acid. The acid is then converted to lactic acid. High-intensity activities lasting up to about two or three min use this energy system during which the reduction of nicotinamide adenine dinucleotide (NAD) is coupled with a net production of two ATP molecules for each glucose molecule metabolized.

acetone does not react with potassium dichromate

The chemical equation for isopropanol, also known as isopropyl alcohol, is C3H8O or CH3CHOHCH3. It is a colorless, flammable chemical compound commonly used as a solvent, cleaning agent, or disinfectant.

Potassium chlorate can be decomposed into potassium chloride and oxygen gas when heated. The chemical equation for this reaction is 2KClO3(s) → 2KCl(s) + 3O2(g).

I'm sorry. I'm not quite clear on what you want here. Do you want to know what charge is present on the reactants or the products of a chemical equation?

In most cases, I'd say check your periodic table of the elements for the charge of the individual atoms, then add them all up.

Are you asking about Ionic Charges where one atom has a number of possible charges on it, such as Fe(2)O(3) and you don't know if the Iron is +2 or +3 kind?

Just remember that it has to balance out to a net charge of 0 (unless your teacher's being sneaky, and that should be noted in the formula with a + or - at the end). With my example above, since Oxygen is always a -2 charge, that's a total of -6, so for the Iron to balance it out it needs to be +6 total. Since there are 2 Iron atoms each one has a charge of +3.

Hope that helps.
