Chemical Equations

First, calculate the molar mass of C12H26 (dodecane) by multiplying the molar masses of carbon and hydrogen and summing them up. Then determine the moles of C12H26 in 3.73 kg by dividing the mass by the molar mass. As the balanced equation shows a 1:12 ratio between C12H26 and CO2, multiply the moles of C12H26 by 12 to find the moles of CO2 produced. Finally, determine the mass of CO2 by multiplying the moles by its molar mass.

The first ionic equation is: OH- (aq) + NH4+ (aq) -> NH3 (aq) + H2O.

The change upon heating described in the question is physical only and does not involve ions; the dissolved ammonia simply passes from the aquated state to the gas phase, because the solubility of gases in liquids decreases with increasing temperature.

:A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.An equation is balanced by changing coefficients in a somewhat trial-and-error fashion. It is important to note that only the coefficients can be changed, NEVER a subscript.

The balanced chemical equation for the reaction between magnesium and copper(II) nitrate is: Mg + Cu(NO3)2 -> Mg(NO3)2 + Cu

The balanced chemical equation for heating magnesium metal is:

2Mg(s) + O2(g) -> 2MgO(s)

a coefficient is the number that falls before the chemical formula.so,in 3Mg N2 - Mg3N2 there are 3 coefficients in that chemical equation.

These are present on the reactants side.

I2(l) + H2O(l) -> OI-(aq) + 2H+(aq) + I-(aq)

To find the grams of NaCl with 2.34 moles of Cl2, you need to consider the molar ratio. For every 1 mole of Cl2, there are 2 moles of Cl in NaCl. So, 2.34 moles of Cl2 would be equivalent to 4.68 moles of Cl in NaCl. Using the molar mass of NaCl (58.44 g/mol), you can calculate that 4.68 moles of NaCl would be approximately 273.64 grams.

Ca(OH)2 + (NH4)2SO4 --> CaSO4 + 2NH3 + 2H2O

Calcium Hydroxide + Ammonium Sulphate --> Calcium Sulphate + Ammonia + Water

Residue or ash is left behind after combustion because not all the fuel is completely burned during the process. Incomplete combustion can occur due to insufficient oxygen supply, poor fuel-air mixture, or low combustion temperatures. The residue can also contain unburnt carbon, which is a byproduct of incomplete combustion.

CO2 has 1 carbon atom and 2 oxygen atoms. Carbon has an atomic mass of about 12 and oxygen 16. The total for carbon dioxide is 12 + 16 + 16 = 44. The make 88gms you would need the same proportion in grams as the proportion of atomic masses. The answer is therefore 64 grams of oxygen. For each tonne of carbon burnt the oxygen from 15000 cubic metres of atmosphere is needed.

No - they are usually balanced by changing the numbers before the molecules.

The dissociation equation for Pb(NO3)2 in water is:

Pb(NO3)2(s) → Pb2+(aq) + 2NO3-(aq)

There is no equation for Sulfur, it is an element with the symbol S and that is all. Equations are used to represent chemical reactions and formulas are used to represent chemical compounds. Elements just have a symbol because they only contain one sort of atom.

The chemical equation for a toxic chemical will depend on the specific chemical in question. Could you please provide the name or formula of the toxic chemical you are referring to?

The chemical equation for the presence of alkali soil is typically seen as high levels of sodium carbonate (Na2CO3) and bicarbonate (NaHCO3) in the soil, which increase the pH level. Excessive levels of these compounds can affect plant growth by interfering with nutrient uptake and causing toxicity. Agricultural practices like soil amendments or proper irrigation management can help neutralize the soil.

The chemical equation for the formation of stainless steel, known as inox, is typically: iron (Fe) + chromium (Cr) + nickel (Ni) + carbon (C) + other elements → stainless steel. The specific proportions of each element can vary depending on the grade and type of stainless steel being produced.

Drain cleaners typically contain sodium hydroxide (NaOH) or sulfuric acid (H2SO4) as the active ingredient. The chemical equation for sodium hydroxide acting as a drain cleaner is: NaOH + H2O -> Na+ + OH- + H2O. Sulfuric acid's equation as a drain cleaner would be: H2SO4 + H2O -> H3O+ (hydronium ion) + HSO4- (bisulfate ion).

Compound formula:

Al2O3 + C --> Al + CO2

Make it balanced:

2 Al2O3 + 3 C --> 4 Al + 3 CO2

The balanced chemical equation for the reaction between cesium hydroxide solution (CsOH) and phosphoric acid (H3PO4) is: 3 CsOH + H3PO4 → Cs3PO4 + 3 H2O

This equation is balanced because there is an equal number of atoms of each element on both sides of the equation.

In the bank space for the burning of fossil fuels, you would typically see oxygen (O2) as the reactant needed for combustion to occur. The balanced equation would be: Fossil fuel + O2 → CO2 + H2O + energy.
