Answer: carbon-containing compounds with covalent bonds
Explanation:
The term "organic compound" refers to the group of carbon-containing compounds such as glucose (C6H12O6), Propane (C3H8), ethyne (C2H2) etc, where the carbon atoms in them are covalently bounded to other atoms such as hydrogen, oxygen, phosphorus, nitrogen etc
Examples of organic compounds are ethanol (C2H5OH), ethylamine (C2H5NH2) etc.
Thus, organic compound are carbon-containing compounds with covalent bonds to other atoms.
Answer:
Explanation:
When there is difference between the concentration of the content of a cell and the solution surrounding the cell, there will be an Electrochemical gradient or Concentration gradient. Therefore, some solute will tend to move from the region of high concentration to the region of lower concentration through the cell membrane.
Such a movement is called Primary Active Transport
Water-rich solutions carrying metallic salts fill cracks and form <u>veins</u>.
Answer:
Fractional distillation is used for the purification of water as well as separating acetone and water.
Fractional distillation is used in several industries like oil refineries and chemical plants mainly for purification and separation of many organic compounds.
Answer:
The answer to your question is below
Explanation:
Propane = C₃H₈
Process
1.- Write the chemical reaction
C₃H₈ + O₂ ⇒ CO₂ + H₂O
balanced chemical reaction
C₃H₈ + 5O₂ ⇒ 3CO₂ + 4H₂O
Reactants Elements Products
3 C 3
8 H 8
10 O 10
b) Standard enthalpy
Propane -104.7 kJ/mol
Oxygen 0 kJ/mol
Carbon dioxide -393.5 kJ/mol
Water -241.8 kJ/mol
ΔH° = ∑ΔH° products - ∑H° reactants
ΔH° = 3(-393.5) + 4(-241.8) - [(-104.7) + 0]
-Simplification
ΔH° = -1180.5 kJ/mol - 967.2 kJ/mol + 104.7 kJ/mol
ΔH° = - 2042.5 kJ/mol
This reaction is exothermic because ΔH° is negative.
