Answer:
2NaOH + 2Al +2H2O = 2NaAlO2 +3H
Explanation:
Aluminum is an amphoteric element it reacts with both bases and acids to form a salt and hydrogen gas.The reaction is highly exothermic.
The answer is (3) its aqueous solution conducts an electric current. The definition of electrolyte is a substance that will ionize when dissolved in suitable ionizing solvents such as water.
Answer:
D. bonds holding together two atoms of the same kind of metal.
Explanation:
Metallic bonds are very special kinds of interatomic forces that holds metals together and confers such unique properties on them.
The formation of this bond type is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.
- The metallic bond is usually an attraction between the positive nuclei of all the closely packed atoms in the lattice and electron cloud jointly formed by all the atoms by losing their outermost shell electrons.
- This is as a result of low ionization energy.
C6H8 + 8O2 ===> 6CO2 + 4H2O ... balanced equation
moles hexane = 54.3 g x 1 mol/80 g = 0.679 moles
moles O2 = 78.5 g x 1 mol/32 g = 2.45 moles
Limiting reactant is Oxygen (O2) since need 8 x as much as C6H8
Theoretical yield of CO2 = 2.45 mole O2 x 6 mole CO2/8mole O2 = 1.84 moles CO2
1.84 moles CO2 x 44 g/mol = 80.9 g (answer to 3 sig figs)
depending on if your question possesses this values
<span>The wick merely transports some of the liquid up to where vaporizes.It is not part of reaction but it does affect the reaction rate greatly,so it is a sort of catalyst in that time.if you wrap the wick in the aluminum it will block the transport the wax and it will wither go out less or brightly</span>
