Yes HYDROGEN can be produced from chemicals in a small scale by reacting Zinc and Dilute sulphuric acid .
EQUATION: Zinc + Sulphuric Acid = Zinc Sulphate + Hydrogen
Zn(s) + H2SO4(aq) -----> ZnSO4(aq) + H2(g)
DESCRIPTION:
- Dilute sulphuric acid is added to the granulated zinc in the flask via the thistle funnel.
-The hydrogen gas is collected by downward displacement of water
PROPERTIES: Colourless, odourless gas almost insoluble in water.
Far lighter than air (lightest gas in fact).
Burns readily in air. Is a reducing agent.
TEST: Explodes with a pop in the presence of air (oxygen) when a flame is introduced.
Water is the only product 2H2 + O2 = 2H2O
It may not be produced by reacting aluminium with lime .

I don't think that combination is strong enough to produce sufficient Hydrogen.
In my high school science classes, we would put some small pieces of Zinc in a test tube and then pour HydroChloric Acid over it (HCl). That reaction will release plenty of hydrogen gas.

It cant be produced by reacting aluminium with lime.it can be produced by reacting any metal with any acid for eg.
Aluminium + vinegar--> Aluminium acetate + Hydrogen

degree some ice cubes, calculate the quantity of each physique upload the volumes jointly to get the entire quantity of ice. permit all the ice cubes soften so as that there is not extra ice left---there is in uncomplicated terms water. place a funnel right into a graduated cylinder. Pour the water into the funnel. do away with the funnel. study the quantity of water. Is the quantity of water extra suitable or below the quantity of ice??? by ability of what proportion % What does this mean with regard to density?
