Answer:
C2H5OH(l) +3O2(g) → 2CO2(g) + 2H2O(l)
it is combustion reaction and heat is also produced.
Explanation:
This is oxidation reduction reaction which is also called redox reaction.
C2H5OH is reducing agent while O2 is oxidizing agent.
Chemical equation:
C2H5OH + O2 → CO2 + H2O
Now we will balance the equation. In given chemical equation two carbon atoms on the left side and one carbon atom on the right side. While six hydrogen atoms are present on the left and just two hydrogen on right side. We will write coefficient two with carbon dioxide and and three with water molecules.
C2H5OH + O2 → 2CO2 + 3H2O
now we will balance the oxygen atoms. we can see there are three oxygen atoms on the left and seven on right side. we will write coefficient three with oxygen on left and equation becomes balance.
C2H5OH + 3O2 → 2CO2 + 3H2O
Complete chemical equation with physical states:
C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)
Answer:
Oxygen atoms form two double bonds in silicon(IV) oxide.
Silicon(IV) oxide has a high melting point.
Explanation:
Silicon dioxide is structurally analogous to carbon dioxide in the sense that it also contains two oxygen atoms that are double bonded to silicon the central atom in the molecule.
Silicon dioxide has a very high melting point of about 1710 degrees centigrade because of its large macromolecular structure which requires much energy to break such intermolecular interactions.
When amino acids are linked together, they form a peptide bond. When it joins two amino acids, it forms a dipeptide bond. When a long chain of amino acids are joined by peptide bonds, it becomes a protein. As shown in the picture, it loses H-OH molecules.
So, it will appear in the product side as a H₂O molecule.
The independent variable is the exercise.
The dependent variable is the weight they gained.
The controlled variable is the groups, and how long(a month).
Hope it's correct, sorry if it's wrong.
