When flame is applied to ethanol (C2H5OH), it undergoes combustion, a chemical reaction where it reacts with oxygen (O2) in the air to produce carbon dioxide (CO2), water (H2O), and heat. The balanced chemical equation for the combustion of ethanol is:
C2H5OH + 3O2 → 2CO2 + 3H2O
In this reaction, the ethanol molecule breaks apart, and its carbon and hydrogen atoms combine with oxygen atoms from the air to form carbon dioxide and water vapor, respectively. This reaction releases a significant amount of heat energy, which is why ethanol is used as a fuel in alcohol burners, stoves, and engines.
When you observe a flame applied to ethanol, you will see a blue-colored flame, indicating complete combustion. The heat produced by the combustion of ethanol can be used for various purposes, such as heating, cooking, or powering engines.
The chemical formula for reduced iron depends on the oxidation state of iron. In its reduced form, iron typically exists as ferrous ions (Fe^2+). Therefore, the chemical formula for reduced iron is simply Fe^2+.
However, if you're referring to a specific compound containing reduced iron, such as ferrous sulfate (FeSO4) or ferrous gluconate (Fe(C6H11O7)2), then the formula would be different depending on the specific compound.
Yes, we can mix oil and ethanol. This is because oil can dissolve in ethanol.
1. Gaseous Solution- includes gases or vapors dissolved in one another. Two or more gases can form a solution. Air is an example of a gaseous solution. When dry is made up of oxygen gas dissolved in nitrogen gas.
2. Liquid Solution- contain a liquid solvent in which gas, liquid, or solid is dissolved. Water is the most common liquid solution. Many things can be dissolved in it. Table salt is an example of a solid dissolved in a liquid. A liquid and a gas can also be dissolved in a liquid solution.
3. Solid Solution- is a mixture of solids spread equally throughout one another. Metal is an example of a solid solution at room temperature.
As the elemental metal sodium has 11 (eleven) electrons; the same number as the protons, and the atomic no.(Z).
However, sodium will readily lose one(1) electron to form the sodium cation (Na^(+)) .
When it is the sodium cation it has 11 protons, but only 10 electrons.
SO2 = Sulphur dioxide
SO3 = Sulphur trioxide
H2SO3 = Sulphurous acid
H2SO4 = Sulphuric Acid
H2S = Hydrogen sulphide.
CH3CH2SH = Ethanthiol ( The sulphur equivalent of ethanol).
The insulin molecule in the himan organism has a R-S-S-R bridge.
FeS = Iron sulphide.
There are thousands more sulphur (compounds) molecules. . The above is just a selection.
Firdt oh all qrite down the balanced reaction equation.
S(s) + O2(g) = SO2(g)
Note all the molar Ratios are 1:1 ::1
Next calculate the moles of sulphur
moles(S) = 0.5 / 32 = 0.015625 moles. (Equivalent to '1' ratio).
Moles(O2) = 0.015625 ( Equivalenbt to '1' ratio).
Hence mass of oxygen is
mass(g) = moles X Mr
Me( Relative Molecular Mass) of oxygen (O2) is 16 X 2 = 32
Hence mass = 0.015625 X 32 = 0.5 g (mass of oxygen(O2) required).
They are both acidic gases. Reason, when dissolved in water they form carbonic acid(H2CO3) and sulphurous acid(H2SO3)
No such compound as Sodium Chlorine. If you mean sodium chloride, then it is an IONIC Crystalline compound.
For copper, it is an element. It could be both reactant and product. While purifying copper will be the product. But copper would be the reactant in case of preparing hydrogen or copper sulphate salts.
No such substance as 'NaCl2'. However, NaCl (sodium chloride or common table salt) has two atoms viz. 1 x sodium(Na) and 1 x chlorine(Cl).
No compound forms phosphorus. Phosphorus is an element in its own right, and found in the Periodic Table.
Phosphorus is a constituent element in such compounds as phosphorus oxide, phosphoric acid.
Assuming that what the questioner meant (but perhaps did not have sufficient typing flexibility to write) was actually Ca(C2H3O2)2, the chemical name is "calcium acetate" or "calcium ethanoate".
Most of the early molecules play a critical role in living organisms, but the primary three building blocks are carbon, hydrogen, and oxygen (the essential components of a carbohydrate). Nitrogen is a necessary component for life as well, but it's primary use is held to be for the proper usage of the body's electrical discharges (the reason why nitroglycerine is used for people with heart troubles)
First of all , I think you mean AgNO3 , which is Silver Nitrate.
It is NOT a medal/metal .
It is a chemical salt, composed of the nitrate anion (from nitric acid) and the silver cation ( from ??? silver oxide).
Both sand and quartz have the elements silicon and oxygen.
It is a crystalline structure.
The crystalline structures of sand and quartz are slightly different.
Brimstone (burn stone) is also known as "Sulphur" and occurs naturally as a pure element - sulphide. It can commonly found as a by product of removing unwanted sulphur contaminants from natural gas and petroleum.
No, it is the last member of Carbon family.
