Question

4) Combustion Reaction: -C.H..(g) + __02(g) → _C02(g) + H20 (9) Procedure: This is the reaction that occurs in the Bunsen Burner. You do not need to do this reaction. (C. Ho is the chemical formula of butane.) Write a balanced chemical equation. a. Include the physical state on each species. b. Write element, covalent compound or ionic compound under cach species. Write a word equation. What did you see that indicated a reaction occurred or did not occur?

Answer 1

(a) All these compounds are gases, which is indicated in given equation... Like C4H10(g)

(b) Covalent Compound: that contains covalent bond, whch is formed by sharing of electrons. All given compounds in reaction are covalent compounds.

C4H10(g) + Q (g) C018) + HOlg) reactant side to 2 → C-atoms, from First Balance product side, since there reactant has 4c-atom (C4H10) so should be 400 in product side a Balance H-atoms, from reactant side to product side, since there are 10 H-atoms (C4H10) in reactant side, so product should also have 5HO. 3) The Balance of atoms, from product side to Reactant side, since there are 13 0 -atoms ( 4 C0₂ + 5 0 ) . in product side, so reactant side should also have 132 CAH10 (9) + 12 2 2 4 Co (g) + 54. Olg. . It is even a at which combustion normal is occur reaction conditions.

Ionic Compound : that contains ionic bond, which is formed by attraction forces between cation and anion. Examples NaCl, Kbr etc, None of the given compounds are ionic.

For Balancing Please go through attached image, which had detailed explanation about balancing.
