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:
theoretical yield is 12.6f
91.3%
Explanation:
11.5 ÷ 12.6 = 91.3
Answer:
0.8017 pounds
Explanation:
Considering,
1 μg =
1 mg =
Given that:
5.5 μg of the riboflavin is present in 1 g of cheese
Or,
of the riboflavin is present in 1 g of cheese
Requirement = 2.00 mg =
So,
1 g of the riboflavin is present in of cheese
Thus,
of the riboflavin is present in of cheese
Amount of cheese = 363.6364 g
Also,
1 g =
So,
Amount of cheese =
Answer:
density =mass/ volume
Explanation:
isn't this physics ...
so is the mass is 19 g and volume = 25 ml first convert to same units (g/cm3)
1ml = 1cm3
same units so no need to convert
19 divided by 25 = 0.76
0.76 g/cm3
pls give me brainliest
Answer:
propanoic acid forms hydrogen bonded dimers and 1-butanol does not.
Explanation:
Propanoic acids will have a higher boiling point because it forms dimers.
The two compounds have hydrogen bonds as their predominant intermolecular bonds. The intermolecular determines a lot about the physical properties of a substance such as it's viscosity, boiling point, melting point etc.
The two compounds have hydrogen bonds which are bonds that occur between between hydrogen and a more electronegative atom. The electronegative atoms are usually oxygen,nitrogen and fluorine.
In a compound of 1-butanol, we have just a single hydrogen bond between the hydrogen on one compound and the oxygen on the hydroxyl group of another one.
For, propanoic acids, dimerization occurs. Here, we have two hydrogen bonds. The alkanoic acid functional group furnishes the bond. This bond forms between the carbonyl group and hydrogen on a compound and the hydroxyl group and another hydrogen on the same compound.
