Question

For each of the following reactants, predict the products and complete and balance the equations with formulas, symbols, and coefficients. Write the correct physical state (g), (l), (s), (aq). State the type of reaction. a. Calcium is added to water Equation: _____ Type of reaction: _____ b. Metallic aluminum reacts with Fluorine gas Equation: _____ Type of reaction: _____ c. Hexane gas (C_6H_14) burns in oxygen Equation: _____ Type of reaction: _____ d. Barium oxide is added to water Equation: _____ Type of reaction: _____ e. Lithium carbonate is heated Equation: _____ Type of reaction: _____

Explanation / Answer

A)

Calcium + Water

Ca(s) + 2H2O(l) -- >Ca(OH)(aq) + H2(g)

This is a redox reaction

B)

Al(s) + 3/2F2(g) --> AlF3(s)

this is combination + redox

C)

C6H14 + O2(g) --> CO2(g) + H2O(l)

C6H14 + 19/2O2(g) --> 6CO2(g) + 7H2O(l)

this is combsution, i.e. a redox reaction

D)

BaO + H2O --> Ba(OH)2(aq)

this is recombination reaction

E)

Li2CO3+ heat --> Li2O + CO2

This is decomposition reaction
