When propane is burned in air in a process known as combustion it produce carbon (IV) oxide and water
the word equation is as follows,
propane + oxygen--->carbon (IV) oxide + water
chemical equation is as follows
2C3H8 +7O2---> 3CO2 + 8 H2O
hence 2 moles of propane reacted with 7 moles of oxygen to give 3 moles of CO2 and 8 moles of H2o
Answer:
True.
Explanation:
The Hund's Rule states that all orbitals must be singled occupied before any orbital is doubly occupied, and all the electrons at the singly occupied orbitals have the same spin number. By doing that, the electrons filled the lowest energy orbitals first.
The 2p level has 3 orbitals: 2px, 2py, and 2pz. So, when filling it, first put an electron in the 2px, then in the 2py, then and the 2pz (all with the same spin). After that, the remains electrons can be paired up.
Metalloids show both metal and non metal properties
Starch, proteins and nucleic acids have different quantity
of monomers each. Starch has got 5 monomers and they are maltose, cellobios,
sucrose, trehalose and sucrose. There are 20 monomers present in proteins and
they are mainly amino acids of different kinds. Nucleic acids on the other hand
again has 5 monomers. The 5 monomers present in nucleic acid are adenine, uracil,
thymine, cytosine and guanine. Various kinds of organic molecules like the proteins,
lipids, carbohydrates etc. are made up of monomers.
