Which one is more reactive out of Fluorine and Chlorine? Why?
A small portion of Modern periodic table (Group 1) is given. Givet
hydrogen along with metals in this
group.
3. Elements of
group 1, 2, 13 are more reactive as we go down in the
table, why?
Modern periodic table is less defective than Mendeleev's periodic
to justify it.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
