(1) it can be seen from the conditions of full combustion of fuel that the more honeycomb coal holes in domestic coal stove, the larger the contact area between coal and oxygen, and the more full combustion. Therefore, fill: increase the contact area between coal and air to make coal burn fully
(2) the reason why aluminum can be made into foil as packaging material is that aluminum has good ductility. Aluminum reacts with acid to generate salt and hydrogen, such as aluminum chloride and hydrogen
therefore: aluminum has good ductility; 2Al + 6hcl = 2alcl3 + 3H 2 ↑.
(3) the chemical equation of the reaction between calcium hydroxide and carbon dioxide is: Ca (OH) 2 + CO 2 ↓ CaCO3 ↓ + H 2O; So fill in: Ca (OH) 2 + CO 2 ↓ CaCO 3 ↓ + H 2O
